This list represents the rtwmbership at the time the Committee was balloted on the text of this edition. Since that time, changes in the membership may have occurred. A key to cktssifications is found at the front of the book.

Committee Scope: This Committee shall have primary responsibility for documents on the installation, maintenance and use of portable fire extinguishers and equipment. Does not apply to permanently installed fire extinguishing systems even though portions of those systems are portable, such as hose and nozzles which may be attached to a fixed supply of extinguishing agent.

The Report of the Technical Committee on Portable Fire Extinguishers is presented for adoption in 2 parts.

Part I of this Report was prepared by the Technical Committee on Portable Fire Extinguishers, and proposes for adoption amendments to NFPA 10-1994, Standard for Portable Fire Extinguishers. NFPA 10-1994 is published in Volume 1 of the 1996 National Fire Codes and in separate pamphlet form.

The material currently in NFPA 10R will be incorporated into the document as Appendix F, as NFPA 10R is being withdrawn at this time.

Part I this Report has been submitted to letter ballot of the Technical Committee on Portable Fire Extinguishers, which consists of 22 voting members; of whom 20 voted affirmatively, and 2 ballots were not returned (Messrs. Fiedler and Miller.)

Mr. Scheffey voted affirmative and provided the following comments:

"Proposal 10-58 (Table 3-2.1). I do not believe sufficient technical justification has been provided to require an increase in ratings for dry chemical extinguishers. The technical documentation provided with this Proposal emphasized that there is a 95.3 percent effective rate with portables, i.e., the current ratings appear to b e adequate, and there is no demonstrated need to revise tiae ratings. No documentation was provided to revise the extra-high hazard requirement. If minimum discharge time is an issue, then this should be addressed; however, ULI and ULC did not indicate that this was a problem, and NFPA 10 does not specify minimum discharge times.

Proposal 10-111 (New Chapter 6, Portable Extinguishers for Marine Applications). This chapter was submitted and approved with a minimum of review and discussion. The approval by the Committee was made on the assumption that it was appropriate to include this for public comment, recognizing that changes could be made in the public comment period. As currently drafted, the chapter is not ready editorially or technically for inclusion in NFPA 10. Editorially, the chapter contains its own scope, purpose, and definitions, which should be reformatted (e.g., definitions to ,Section 1-3). "Semi-portable" is not defined. Technically, the chapter introduces an A, B, C, and D classification system which is inconsistent with the remainder of NFPA 10. For example, a Type B, Size I extinguisher is equivalent to a 2-1b dry chemical extinguisher (see proposed Table 6-4.3). Yet, Table A-2-1 indicates that a 2-1b stored-pressure dry. chemical unit might be traditionally rated anywhere from 9 to 10BC~

It was not clear that there has been correlation with other appropriate technical committees, e.g., NFPA 302 and the Committee on Merchant Vessels.

I am voting affirmatively on the entire document on the assumption that Chapter 6 will be substantially improved during the public comment period and receive the appropriate, formal correlation with the marine-related committees."

Mr. Carey voted affirmative and provided the following comment: "While we are voting affirmatively on the ballot for NFPA 10,

because of the many improvements to the Standard overall, we do not agree with the Committee's Action on Log #43. We believe the revision proposed in Log #43 is technically accurate and should be accepted by the Committee."

Mr. Lion voted affirmative andprovided the following comment: "I feel that the Committee er redin rejecting ROP 10-22 on

Section 1-4.3, Log #43, the issue shouldbe reviewed at the next Committee meeting."

Mr. Lonabaugh voted affirmative and provided the following comment:

"I disagree with the rejection of Proposal 10-22 on Section 1-4.3, Log #43 because of the difference in requirements between ULC and ULI."

Mr. Huston voted affirmative and provided the following comment:

"I do not agree with the "Reject" decision in the Committee report for Proposal 10-22 on Section 1-4.3, Log #43.

The Proposal to recognize only ANSI/UL extinguishers for USA compliance applications was rejected. The reason for rejection was: No reported problems in the field relative to the differences of rated extinguishers. There are Y..ed2/..fg~ ULC listed extinguishers used for com. pliance requirements in the USA. The. purpose, of the Proposal is to avoid future problems due to the verified differences in the ULC and ULI test programs. The final proposal will also

include the following: Exception: ULC listed extinguishers installed in the USA before June 30, 1996, may continue in use.

Halon 1211 and Halon Replacement Agent Halotron I Data from Underwriters Fire Protection Equipment Directory 1995, and Underwriters Laboratories of Canada List of Equipment and Materials 1995, and Buckeye Fire Equipment Company Sales Brochures Form 300 and Form 400, 1996.

There is an obvious, significant difference in the demand these two test fire systems put on an extinguishing agent. Extinguishers with equal ratings from the two systems are not truly equal.

ULI for Class A testing requires a Vertical Panel Test, a Crib Test, and an Excelsior Test. T h e Panel Test is the most demanding.

ULC requires only a Crib Test. The ULC Crib Test is harder to extinguish than the ULI Crib Test but not as hard as the ULI Panel Test.

Comparing the two different fire rating systems (ULC to ULI) by using dry chemical test results is not valid. Each manufacturer's dry chemical is a proprietary formulation and is different from any other manufacturer's dry chemical."

Mr. Nerat voted affirmative and provided the following comments: "10-11 (1-3) Log #29). Training experience with end-users

indicates, that. a new. Class "K" fire classification for cooking grease fire apphcauons wll only serve to further confuse the general public, which still only has a limited comprehension of the existing portable fire extinguisher classification system and symbols° Many other special fire hazard applications exist without the implementation of a special or new fire classification and symbol. Any new forms of hardware or agents developed for special fire hazards can be tested, listed, and marketed utilizing instruction labels which specifically identify the products intended use, applications and limitations.

10-44 (2-2.1.3) Log #CP4. I feel the existing Class "G" portable fire extinguisher rating test criteria may no longer adequately address NFPA 10 operator safety concerns with the newer forms of wet chemical agents if they are utilized on or about energized electrical equipment. The large quantity of agent expelled through extended metal discharge wands, over longer duration's of time may now present new "agent pooling conditions" where electrical shock hazards to an unsuspecting operator might be possible.

Reference: NFPA 10, 1994 Paragraph (1-3) Class "C" Fires. "...where the electrical conductivity of the extinguishing media is of importance.

Paragraph (1-4.3) Class "C" Rating. No fire test. Agent must be a non-conductor of gl.e,.qd~.Lq,~.

"10-50 (2-3.2.1) Log #39. This verbiage is limiting and may require the replacement of existing types of similar warning placards already being used in the field.

"10-101 (4-5.3.8) Log #58. It was my understanding that the new "halocarbon" agent formulations which were EPA acceptable did not mandate the use of closed recovery systems, listed or otherwise.

"10-105 Chapter 5 Log #CPI 6. No technical information or data was provided that ensured all existing non-compressed gas/low pressure extinguisher cylinders in the field, designed to UL/ANSI specifications would safely meet or pass these new CGA visual inspection recommendations. Various types of extinguisher cylinder materials which have been utilized where the "wall thickness" on the smaller sizes of portable extinguisher cylinders often varies along different points of the vessel. The ability of field service personnel to accurately measure or determine these extremely small limitations is questionable. Visual cylinder inspection limitation recommendations may vary from extinguisher cylinder model to model and any acceptance criteria shouldbe based upon the specific material and construction characteristics known to and provided by the manufacturer."

Mr. Wright voted affirmative and provided the following comment:

"Log #39 (2-3.2.1) Placard should be located adjacent to "means of manual activation of fixed fire extinguishing system" not "_.near each extinguisher".

Part II of this Report was prepared by the Technical Committee on Portable Fire Extinguishers, and proposes for adoption a withdrawal to NFPA 10R-1992, Recommended Practice for Portable Fire Extinguishing Equipment in Family Dwellings and Living Units. NFPA 10R-1992 is published in Volume 10 of the 1996 National Fire Codes and in separate pamphlet form.

Part II this Report has been submitted to letter ballot of the Technical Committee on Portable Fire Extinguishers, which consists of 22 voting members; of whom 19 voted affirmatively, 1 negatively after circulation of negative ballots (Mr. Wright), and 2 ballots were not returned (Messrs. Fiedler and Miller.)

Mr. Wright's negative vote is as follows: "Deletion of residential hose cabinets eliminates the use of proven

fire fighting equipment."

Mr. Huston voted affirmative and provided the following comment:

"The NFPA 10 Committee has not provided adequate information on the protection for oven and stove fires in the residential fire protection section of the proposed revision."

Mr. Petersen voted affirmative and provided the following comment:

"A considerable amount of effort was expended in developing NFPA 10R in transferring it into NFPA 10. A lot of good material has been omitted. There is no indication what happens to it (i.e., the listed cabinet containing a fire extinguisher and hose.)

PART I

(Log #7) 10- 1 - (Entire Document): Accept in Principle SUBMITTER: Nancy E. Frazier, Clarksville, TN RECOMMENDATION: Delete "grease," replace with "flammable liquids." SUBSTANTIATION: The word grease is misleading to the public and ultimately the consumer.

NOTE: Supporting material is available for review at NFPA Headquarters. COMMITTEE ACTION: Accept in Principle. COMMITTEE STATEMENT: The Committee has delineated between Class B hazards and cooking grease (see Committee Proposal 10-8 (Log #CPla for Section F-3.1). They also created a new Class K Classification. Also, see Committee Proposal 10-134 (Log #CP14).

(Log #17) 10- 2 - (Entire Document): Accept in Principle SUBMITTER: Stephanie R. Skaggs, Pacific Scientific RECOMMENDATION: Change the word halon, when used genetically, to halogenated agent. (Sections which this applies includes 1-3, 1-4.3, 3-2.1.1, 4-3.3.3, 4-4.1.4, 4-5.3.7, 4-5.3.8) SUBSTANTIATION: Since halons are no longer in production and halogenated agents are being commercialized to replace halons, these halon replacement agents should be considered for inclusion in NFPA 10. With the provision of certain specific information and by changing the word halon, when used generically, to halogenated agent, the inclusion of halon replacement agents will be accomplished. COMMITTEE ACTION: Accept in Principle. COMMITTEE STATEMENT: See Committee Action on Proposal 10-59 (Log #52), 10-72 (Log #55), 10-78 (Log #56), 10-100 (Log

, #119), and 10-101 (Log #58).

COMMITTEE ACTION: Accept in Principle. Add the following as A-2-3.2: "Portable fire extinguishers for Class K fires are intended to be

used only after the fixed automatic fire extinguishing system has actuated."

Since the fixed fire extinguishing system will automatically shut-off the fuel source to the cooking appliance, it is preferential to activate the fixed system before using a portable fire extinguishers. In this instance, the portable fire extinguisher is supplemental protection. COMMITTEE STATEMENT: The suggested text is advisory and is therefore appropriate for the appendix.

(Log #33) 10- 6 - (1-3): Accept in Principle SUBMITTER: Jack Nicholas, FEMA RECOMMENDATION: Add the following text:

"Halogenated agents also included hydrofiuorocarbon (HFC), hydrochlorofluorcarbon (HCFC), perfluorocarbon (PFC), and fluoroiodocarbon (FIC), halocarbon-type (halon replacement) agents. SUBSTANTIATION: Other halogenated agents are now commercially available and should be included in this standard. COMMITTEE ACTION: Accept in Principle. COMMITTEE STATEMENT: See Committee Action on Proposal 10-13 (Log #41).

Exception: Portable fire extinguishers for cooking grease fires are intended to be used only after the fixed automatic fire extinguishing system has actuated. SUBSTANTIATION: Siv ce the fixed automatic fire extinguishing system will automatically shut-off the fuel source to the cooking appliance, it is preferenti:d to activate the fixed automatic system before using a portable fire extinguisher. In this instance, the portable fire extinguisher is supplemental protection.

(Log #CPla) 10- 8 - (1-3, Appendix F): Accept SUBMITTER: Technical Committee on Portable Fire Extinguishers RECOMMENDATION:

1. Add the following definitions to section 1-3: Automatic Residential Fire Extinguisher Unit. A fixed

extinguishing device, fitted with an automatic means of operation and designed, tested, and listed for use on a particular type of hazard as identified o n its label

Carbon Dioxide. Carbon dioxide is a colorless, odorless, electrically nonconductive inert gas that is a suitable medium for extinguishing Class B and C fires. Liquid carbon dioxide forms dry ice snow when released directly into the atmosphere. Carbon dioxide gas is 1.5 times heavier than air. Carbon dioxide extinguishes fire by reducing the concentrations of oxygen, the vapor phrase of the fuel, or both in the air to the point where combustion stops.

Hydrostatic Testing. Pressure testing of the extinguisher to verify its strength against unwanted rupture.

Residential Fire Extinguisher, General Use. A fire extinguisher that has been specifically investigated, tested, and listed for use only in and around the home (one- and two-family dwellings and living units within multifamily structures) for the purpose of suppressing or extinguishing a fire.

Residential Fire Extinguisher, Special Purpose. A fire extinguisher designed, tested, and listed for a particular type of hazard as specified on its label.

9. Replace Appendix F with the following: Appendix E Selection of Home Fire Extinguishing Equipment

This Appendix is not part of the requirements of this NFPA document but is included for informational purposes only.

The provisions of this appendix section apply to the selection, installation, and maintenance of fire extinguishing equipment for one- and two-family dwellings and living units within multifamily structures. The fire extin~u.ishing equipment is intended as a first line of defense to cope with fires of limited size. This equipment is needed even though the dwelling or living unit is protected by an automatic sprinkler system, fire or smoke alarm systems or both, single station smoke detectors, or other fixed fire suppression or detection systems. The recommendations given herein are MINIMUM. Depending upon the conditions existing in each living unit, additional extinguishers or ones of larger capacity may be advisable.

193

N ~ ' P A 1,0 - - F 9 7 R O , P

NOTE: For more information on automatic sprinkler systems for the home, see NFPA 13D, Standard for the Installation of Sprinkler Systems in One- and Two-Family Dwellings and Mobile Homes, and NFPA 13R, Standard for Installation of Sprinkler Systems in Residential Occupancies up to and Including Four Stories in Height. For more information about fire or smoke alarm systems or both and single station smoke detectors, see NFPA 72, Natioanl Fire Alarm Code.

The purpose of this appendix section is to provide, guidance, for the owners and occupants of one- and two-family dwelhngs and living units within multifamily structures in selection, use, installation, and maintenance of fire extinguishing equipment.

F-1 General Recommendations. Selection of a fire extinguisher for home use should be made with the understanding of an extinguisher's capacity (or its rating) along with the potential fire hazards in the home. Depending on the conditions existing in each living unit, additional extinguishers or ones of larger capacity may be advisable.

Minimum recommendations per floor level are: (a) A single extinguisher rated 2-A:10-B:C or higher, or (b) One extinguisher rated 2-A or higher and a second

extinguisher rated IO-B:C or higher, or 17-1.1 Extinguishers installed in the home should meet the

requirements of Section 1-4. F-1.2 Attached Garages. One extinguisher rated 2-A:10-B:C or

higher should be provided toprotec t an attached garage that is under the home or connectedto the home by a common wall.

F-1.3 Detached Garages. Where provided, extinguishers for detached garages should have a ra t ingof 2-A:10-B:C or higher.

F-l-4 Due to the volume of flammable liquids normally present in garages (associated with automobiles, lawn mowers, snow blowers, workshops, etc.). A larger extinguisher than those meeting the minimum recommendations should be specifically installed for protection.

17-2 Fire Extinguisher Types. F-2.1 The following types of fire extinguishers are recommended

for installation and use in family dwellings and living units: (a) Dry chemical (b) Water, AFFF, FFFP, antifreeze (c) Halogenated agent (d) Carbon dioxide. F-2.2 The following types of fire extinl.guishers are NOT

recommended for installation and use m family dwellings and living units:

(a) Inverting types (soda acid, cartridge operated water/antifreeze, foam).

(b) Vaporizing liquid (carbon tetrachloride, chlorobromomethane, methyl bromide).

(c) Extinguishers rated prior to 1955 and marked B-I,C-1 on the nameplate.

(d) Fire extinguishers not listed or labeled. F-3 Application for Specific Hazards.

, F-3.1 Cooking Grease Fires. Cooking grease fires require the use of extinguishers that will extinguish the fire from a safe distance, not causing splashing of the burning grease and not permitting reignition of the fire. This can be achieved by a special purpose home fire extinguisher listed for residential grease fires or an automatic fire extinguisher unit listed for residential range top Pdrotection. Other agents may have limited effectiveness. An ABC

ry chemical extinguisher is not the extinguisher of choice because of the possibility of reignition.Water, AFFF, or FFFP may cause dangerous splashing of burning grease and may cause fire to spread. WARNING-do not attempt to pick up a pot or pan containing burning greasel To avoid personal injury and to avoid spreading the fire, fight the fire inplace. Shut off the heat source as soon as it is safe to do so to avoid fire reflash.

F-3.2 Electronic Equipment Fires. Where provided, extinguishers for the protection of delicate electronic equipment, such as TVs, computers, and stereos, should have a 1-B:C rating or higher and be of the carbon dioxide or halogenated agent types.

F-3.3 An automatic residential fire extinguisher unit is designed and listed for the protection of a specific hazard. It shall only be utilized in accordance with the manufacturers' specifications.

F-4 Extinguishing Equipment Guidelines F-4.1 Minimum Placement. A minimum of one portable fire

extinguisher, meeting the general requirements of Section F-l, should be provided per floor level of a living unit, with a maximum of 40 ft (12 m) traveldistance to the equipment.

F-4.2 Installation. Before installing any fire extinguishing equipment, read and understand the installation and use instructions, including the limitations, cautions, and warnings contained on the equipment and in the owner's manual.

F-4.2.1 Portable fire extinguishers should be installed as follows:

(a) In an accessible spot, free from blocking by storage and equipment, and near room exits that provide an escape route. (b) So that the top of the fire extinguisher is not more than 5 ft

(1.5 m) above the floor and not less than 4 in. (10.2 cm) above the floor. The extinguisher should be easy to reach and remove and should be placed where it will not be subject to damage or tampering.

(c) On hangers, or in the brackets supplied by the manufacturer, mounted in cabinets or placed on shelves.

(d) Placed so that the operating instructions on the extinguisher face outward.

F-4.3 Safety Precautions. For personal safety, observe the following precautions for locating and using fire extinguisher:

(a) Most f i resproduce toxic decomposition products of combustion, andsome materials may produce highly toxic gases. Fires may also consume available oxygen or produce dangerously

I high exposure to convected or radiated heat. All of these may affect the degree to which a fire can be safely approached with extinguishing equipment.

(b) Discharging portable fire extinguishers from too close a distance on cooking grease fires may cause splashing of the burning grease or oil and spread the fire. The recommended distance for operating portable fire extinguishers is shown on the label (see F-3.1).

(c) Portable fire extinguishers should not be installed adjacent to the location of a potential fire hazard but should be accessible to the hazard.

(d) Halogenated agent extinguisher labels contain information as to the minimum volume of room that can be properly and safely protected. When using these extinguishers, avoid breathing the discharged agent or the gases produced by the thermal decomposition of the agent Evacuate and ventilate the area immediately after use.

(e) The use of a carbon dioxide extinguisher(s) in an unventilated space can dilute the oxygen supply. Prolonged occupancy of such spaces can result in loss of consciousness due to oxygen deficiency.

(f) Extinguishers not classified for Class C hazards present a shock hazard if used on fires involving energized electrical equipment.

(g) Dry chemical extinguishers, when used in a small unventilated area, may reduce visibility for a period of up to several minutes.

F-4.4 Procedures Following the Use of Fire Extinguishers. For personal safety and proper operation, it is essential that the instructions on the extinguisher label and contained in the manual be followed. It is also essential that once the extinguisher is used, it must be refilled or replaced prompdy. Even if only a short burst of agent is released, the extinguisher may lose the rest of its )ressure. F-5 Inspection, Maintenance, and Servicing of Home Fire

~xtinguishing Equipment F-5.1 General. F-5.1.1 This chapter is concerned with the inspection,

maintenance, andservicing of fire extinguishers. F-5.1.2 The homeowner or occupant is responsible for assuring

hat inspection, maintenance, and servicing of fire extinguishers is )erformed in a timely manner by competent individuals. 17-5.2 Inspections. F-5.2.1 Inspections should be performed when the fire

.~xtinguisher is initially placed in service and thereafter at approximately 30-day intervals. Inspections should be performed in accordance with the owner's manual supplied with the fire extinguisher.

F-5.2.2 Inspection procedures should include a check of at least the following:

(a) The equipment is in its designated place, and its operating instructions face outward.

(b) Access to the fire extinguisher is not obstructed. (c) Operating instructions are legible. (d) Any seals or tamper indicators are not broken, missing, or in

need of replacement. (e) Pressure gage or indicating devices, if provided, are in the

operable range or position. (f) There is no evidence of corrosion or physical damage. F-5.2.3 f f the inspection of the fire extinguisher reveals any

deficiency under 5-2.2(a) and (b), immediate corrective action should be taken by the homeowner or occupant. Deficiencies related to 5-2.2(c) thru (f) indicate the need fo r immediate maintenance and servicing.

F-5.3 Maintenance and Servicing. F-5.3.1 Maintenance and servicing of fire extinguishers should be

)erformed by fire extinguisher servicing companies that have the

194

N F P A 10 m F 9 7 R O P

proper tools, recharge materials, lubricants, manufacturer 's servicing instructions, and rep lacement parts.

F-5.3.2 Manufacturer 's instructions specify servicing of rechargeable fire extinguishers after any use. The frequency of internal maintenance and hydrostatic testing is specified in the owner's manual and in Table 17-5.3.2.

1. Nonrechargeable dry chemical extinguishers do not require a 6-year internal inspection but should be removed from servme 12 years after the date of mmaufacture.

2. Nonrechargeable haiogenated agent extinguishers do no t require an internal inspection but should be removed f rom service 12 years from the date of manufacture. The extinguishers should be re tu rned to the manufacturer or the manufacturer 's designated agent for reclaiming of the halogenated agent.

F-6 General Recommendat ions . F-6.1 Fire Extinguishers. F-6.1.1 Fire extinguishers should be mainta ined in a fully charged

and operable condit ion mad kept in their designated places at all times when they are no t being used.

F-6.1.2 Inverting-type fire extinguishers are n o t r e c o m m e n d e d and should be removed f rom service.

F-6.2 Owner 's Manual. Am owner's manual is provided by the manufacturer of listed equipment , giving instructions and cautions necessary to the installation, operation, inspection, maintenance, and disposal or recharging of fire extinguisher(s). The manual refers to this s tandard a n d N F P A 10, Standard for Portable Fire Extinguishers, as appropriate , as a source of detailed instructions. The manual s h o u l d b e carefully read and kept in a convenient place for future reference.

F-6.3 Principles of Fire Extinguishment. Many fires are small at origin and may be exting~lished by the use of fire extinguishers or small hose streams. The fire depa r tmen t should be notified as soon as a fire is discovered. This alarm should no t be delayed awaiting results of application of home fire extinguishing equipment .

Portable fire extinguishing equipment can represent an important segment of a home f i repro tec t ion program. If a fire starts in your home, get people out o f the house and call the fire depar tment ; then use a fire extinguisher. In fighting a residential fire:

(a) Keep near a door that can be used as an escape route. (b) Stay low. Avoid breathing the heated smoke, vapors, or fumes

as much as possible, as well as the extinguishing agents. (c) If you feel conf ident in attacking the fire, use the appropriate

fire f ight ing equipment . [f the fire is no t quickly extingut~shed -, get o u t o f the building, closing door(s) beh ind you, and do no t reenter.

F-6.4 Responsibility. The h o m e o w n e r / o c c u p a n t has an obligation for the care and use of the fire extinguishing equipment at all times. The nameplate(s) and instruction manual should be read and thoroughly unders tood by all persons who may be expected to use the equipment . The instruction manual should be kept in a safe place and periodically reviewed.

The presence of an extl'nguisher in the home is no t worthwhile unless the homeowner is willing to:

(a) Unders tand how to use the device properly, (b) Instruct family merabers who may Iaave to use it, and (c) Maintain and recharge it according to the manufacturer 's

instructions. The owne r /occupan t must see that everyone unders tands how to call the fire depar tment and stress that they should do so for every fire, no matter how small it may be.

Homeowners/occupant. , ; should recognize fire hazards on his or he r proper ty and plan in advance exactly how, and with what, a fire will be fought. It is impor tant for homeowners to unders tand that extinguishers of the sizes discussed have a discharge time of only 8 to 60 sec; in actual use, no time can be wasted de termining the best way to use the device. Instructional help on fire extinguisher use may also be obtained from local fire depa r tmen t personnel . SUBSTANTIATION: The fact that only a relatively small number of copies of NFPA 10R have been sold since its inception is an indication that it is no t being used as it should. Certainly, anyone

who is buying all of the Fire Codes will have a copy but that is not necessarily an indication of its actual use. On the other hand, NFPA 10 is used widely and is on the bookshelf of every one involved in portable fire extinguisher selection, distribution, and use. Accordingly, to gain maximum exposure, it would seem preferable to have NFPA 10R included as an Appendix of NFPA 10. NFPA 10R is generally an advisory documen t ra ther than mandatory and is very appropriate as appendix material in NFPA 10. COMMITTEE ACTION: Accept.

(Log #CP17) 10- 9 - (1-3 Carbon Dioxide): Accept SUBMITTER: Technical Commit tee on Portable Fire Extinguishers RECOMMENDATION: Add the following definition for "Carbon Dioxide" to section 1-3 as follows:

Carbon Dioxide. Carbon dioxide is a colorless, odorless , electrically nonconduct ive inert gas that is a suitable med ium for extinguishing Class B and C fires. Liquid carbon dioxide forms dry ice snow when released directly into the atmosphere. Carbon dioxide gas is 1.5 times heavier than air. Carbon dioxide extinguishes fire by reducing the concentrat ions of oxygen, the vapor phase of the fuel, or both in the air to the point where combust ion stops.

(Log #41) 10- 13 - (1-3 Halogenated Agents): Accept SUBMITTER: Paul O. Huston, Paul Huston & Assoc. RECOMMENDATION: Change the definition of Halogenated Agents to read as follows:

Halogenated Agents. Halogenated (clean) agents referenced in this standard are the following types:

(a) Halons~ Bromochlorodifluoromethane (Halon 1211), bromotrifluoromethane (Halon 1501), and mixtures of Halon 1211 and Halon 1301 (Halon 1211/1301).

Note: Halon 1211 and Halon 1301 are included in the "Montreal Protocol on Substances that Deplete the Ozone Layer," signed September 16, 1987. In compliance with national regulations, production of halons ceased on January 1, 1994.

(b) Halocarbons. Halocarbon agents include hydrochlorofluorocarbon (HCFC), hydrofluorocarbon (HFC), perfluorocarbon (PFC), and fluoroiodocarbon (FIC), type agents.

Note: See NFPA 2001, "Standard on Clean Agent Fire Extinguishing Systems," for more information of halocarbon agents. SUBSTANTIATION: The production of balons was cut back to 1986 levels by E.P.A. regulations in 1992o Further cutbacks occurred in 1995; and on January 1, 1994, government regulations required that Halon 1211 and Halon 1301 production stop. Environmentally friendly Haion 1211 replacement (streaming) agents have been under development since 1990. Several types of agents are available in ULI andULC listed fire extinguishers. It has been difficult, and sometimes impossible, to adequately meet the fire protection needs of the growing use of electronic devices in commercial, industrial, and business applications. Adding recognition of these new proven (halogenated) Halon 1211 replacement agents will allow the fire protection industry to satisfactorily meet those needs. It will also provide guidance for installation, use, and maintenance of the halon replacement agents in accordance with the requirements of NFPA 10. COMMITTEE ACTION: Accept.

SUBSTANTIATION: Reference to halogenated agents rather than balon will encompass the new halogenated agents and will be consistent with the defnit ion of halogenated agents. The addition

of an ODP limit for listed recovery systems is to conform with U.S. EPA requirements. COMMITTEE ACTION: Accept.

Revise the first paragraph as shown and the second paragraph remains but change "halon" to "agent":

"The system's supply or recharge and recovery container shall be capable of maintaining the agent in a sealed environment until it is reused or returned to the agent manufacturer."

SUBSTANTIATION: The Canadian Regulations and Authorities only recognize portable fire extinguishers which are listed and labeled to Canadian fire test and performance standards. Equ ipment approved to American National Standards Institute ANSI /UL standards are not acceptable for compliance to Canadian regulations. Canadian fire test and performance standards are different than the ANSI /UL standards. For example: the amount of clean agent needed to extinguish a Canadian class 1A fire can vary by a factor of 2 with respect to the amount needed to extinguish an ANSI/UL 1A fire with the same agent.

By separating the Canadian and ANSI standards into two specific jurisdictions, each jurisdict ion can adjust the standard's requ i rement to comply with its close-at-hand exper ience commensura te with its own national laws and regulations without compromis ing the other jurisdict ion's requirements .

Exception: Original manufacturer 's labels or labels that specifically relate to the extinguisher's operation or fire classification. COMMITTEE STATEMENT: 1. The "warning information" phase in the exception, was originally in tended to provide the extinguisher manufacturers with a means to address the min imum area /volume decomposi t ion warning requirements for halon 1211 extinguishers.

2. The p lacement of this addit ional information on the f ront of an extinguisher might h inder or delay an operator f rom putt ing the uni t into operation.

3. The main funct ion of HMIS information on the extinguisher is for addressing the after use exposure problems sometimes requested by medical personnel , not to prohibi t or direct the extinguishers use or application.

(Log #6) 10- 29 - (1-7): Accept in Principle SUBMITTER: Charles R. Higgins, Briston-Myers Squibb Company RECOMMENDATION: My concern is that we are put t ing too many labels on extinguishers which may confuse the novice user. My suggestion would be to place labels only to the back side of extinguishers so that only the necessary information is shown to the user when the uni t is hanging on a wall or in a cabinet. SUBSTANTIATION: I am writing to you with some concern about NFPA 10, Section 1-7 dealing with "Identification of Contents" using a label, tag stencil, or similar manner or identification.

In the past it has been the practice to put only the most vital information for operat ion on a fire extinguisher in order n o t to confuse the novice operat ion of which the majority of the users come from.

I have in f ront of me an older fire extinguisher which has a band with recharge instructions, maintenance, UL lab approvals, ID#, wts, FM approval, and manufacture name. Also on this 1 3 / 4 in. wide x approximately 14 in. long band is the "To Use Directions" and the old "diamond, Square, and Circle" marking system. Through the years the new sticker symbol system has been placed along with a six (6) year main tenance and twelve (12) hydrotester sticker. In the last year or so, we have had to place a DOT sticker and a large HMIS label which you address in NFPA 10, Section 1-7. This does not end here in that we have also affixed a small company inventory label with a name and number on it. COMMITTEE ACTION: Accept in Principle.

(Log #100) 10- 30 - (1-7(0): Accept SUBMITTER: Norber t W. Makowka, NAFED RECOMMENDATION: Delete the word "as shown on the Material Safety Data Sheet" from this section. SUBSTANTIATION: This phrase has cause much confusion in the field because there is more than one MSDS sheet provided for a fire extinguisher. One MSDS is provided for the pressurizing gas and this sheet is usually issued by the gas manufacturer . Another MSDS is provided for the recharge agent and this sheet may be issued by the fire extinguisher manufacturer or the manufacturer of the agent. Also, most HMIS labels in use contain the name and address of the service agency that pe r fo rmed the recharge of the extinguisher and the service agency does no t issue any MSDS. COMMITTEE ACTION: Accept.

(Log #129) 10- 31 - (1-7(f)): Reject SUBMITTER: Dale B. Nason, Statewide Fire Protection RECOMMENDATION: Delete "or service agency's." SUBSTANTIATION: The problem with the code as it's currently written, is that only the manufacturer of the chemicals used to refill fire extinguishers belong on the label. The service agency did no t manufacture the chemicals and therefore should no t be on the M.S.D.S. The code calls for the name as shown on the M.S.D.S. to be on the label, this can only be the manufacturer . COMMITTEE ACTION: Reject.

Fires. Fire extinguisher provided for the protection of cooking grease fires shall be only of the following types:

(a) sodium bicarbonate or potassium bicarbonate dry chemical type. Installation shall be in accordance with table 3-3.1 for extra "high" hazard.

(b) potassium, acetate bases, potassium, carbonate, based, or potassium citrate based wet chemical type, hsted and labeled for cooking grease fires.

(See NFPA 96, Standard for Ventilation Control and Fire Protection of Commercial Cooking Operations.) SUBSTANTIATION: Wet chemicals have been used in pre- engineered restaurant systems for many years and have been shown to be superior to dry chemicals for extinguishing cookinggrease fires. This differentiation has been reinforced by the fact that no dry chemical systems have been listed to the more rigorous fire test requirements of UL 300, whereas numerous wet chemical systems are now listed. Thus, wet chemicals have been shown to be safe and effective on cooking grease fires, and are particularly suited to the increased hazard resulting from the use of high efficiency cooking equipment and vegetable shortenings. Wet chemicals are now available in portable extinguishers for cooking grease fires. Units from two manufacturers are now listed, and Underwriters Laboratories (UL) has developed a draft test protocol for listing these units.

N F P A 10 - - F 9 7 R O P

To substantiate the effectiveness of wet chemical portable extinguishers on cooking grease fires, FEMA recently conducted a series of tests of wet chemical and dry chemical portable extinguishers on cooking grease fires, in cooperation with UL. Results in die form of a written report and video tape were submitted to NFPA on December 20, 1995 and reviewed by the NFPA 10 Technical Committee on April 1-2, 1996. These tests clearly show that wet chemical portable extinguishers are consistendy more effective than dry chemical extinguishers on cooking grease fires.

The proposed TIA incorporates wet chemical portable extinguishers into NFPA 10. As currently written, paragraph 2-3.2 excludes wet chemicals by allowing only dry chemical types. Since wet chemical type extinguishers are improved technology, commercially available and listed, there is an immediate need to amend NFPA 10.

In summary: 1. Wet chemicals are an advancement in technology. 2. Wet chemicals have been shown to surpass dry chemicals on

cooking~rease fires in a thoroughly documented and widely witnessect test program.

3. Wet chemicalportables are commercially available from multiple manufacturers.

4. Wet chemical portables are currently listed and are labeled for cooking grease fires.

5. The hazard presented by cooking grease fires has significantly increased with the advent of high efficiency, cooking, equipment and the use of vegetable shortening, and reqmres a hlgherlevel of protection.

6. To avoid restriction on the use of this new, superior, and available technology, wet chemical type portable extinguishers need to be added to NFPA 10 immediately. "COMMITTEE ACTION: Accept in Principle.

Replace 2-3.2 with the following: 2-3.2 Fire extinguishers provided for the protection of cooking

appliances that use combustible cooking media vegetable or animal oils and fats shall be listed and labeled for Class K fires.

Exception: Extinguishers installed specifically for these hazards prior to June 30, 1998.

(See NFPA 96, Standard for Ventilation Control and Fire Protection of Commercial Cooking Operations.) COMMITTEE STATEMENT: The Committee feels that there should be new listing criteria specifically for cooking media fires. Additionally the exception permits sodium bicarbonate and potassium, bicarbonate extinguishers installed before June 30, 1998 to remain in lieu of Glass K listed extinguishers. Also, see Committee Action on Proposal 10-64 (Log #38).

must be listed for the intended use. (see NFPA 96, Standard for Ventilation Control and Fire Protection of Commercial Cooking Operations.)" SUBSTANTIATION: The written and video documentation separately provided to you by FEMA as part of their substantiation for the above proposal, more than adequately demonstrates the superiority of the wet chemical portable extinguishers over the dry chemical portable extinguishers, and the appropriateness of their inclusion in the standard now, even ahead of the refinement of their testing protocol and rating. Not only the 40BC, but also the 60BC and 80BC rated dry chemical portable extinguishers proved unreliable in suppressing fires in deep fat fryers, depending on chemical and use. Clearly the ratings developed for the current portables from N-Heptane fires has no applicability with the restaurant fires. The one rated wet chemical extin~{uisher received only a 1BC rating and yet it was always successful wth the restaurant fires, as were the other wet chemical extinguishers that were not rated with N-Heptane. The test data facts supplied by FEMA dearly demonstrate the need for a separate testing protocol for portables to be used on restaurant fires, and a separate identification for this, (I suggest an "R" identification for restaurant use, even though it changes the alphabetical sequence used to date). This protocol should be based on large, high efficiency deep fat fryers, minimally as used in the new UL300 standard. This protocol must also be applied to the dry chemical portables so it can be clearly identified which of them is appropriate for the restaurant fires and which are not. (Even me current use of Extra (high) hazard in Table 3-3.1 of NFPA 10 is obviously not adequate as demonstrated by the FEMA data, and provides only a false sense of security in too many cases). I believe the NFPA 10 Committee should strongly support the development of this protocol, and then incorporates the results in its standard in a separate section for portables applied to restaurant applications. This section should also include the caution not to use any gas type extinguishers (CO 2 and Halon) on restaurant applications, nor any AFFF, nor any FFFP, as the former will not saponify to keep the fire out, and the latter will actually combust in the hot shortening. Samples of each of portable currently found in restaurants should be tried against the new protocol to establish their appropriateness or not, so these can be adequately commented on in the revised NFPA 10 Standard.

The placard shall identify the primary means of cooking surface protection as the fixed fire extinguishing system installed over the appliances in the exhaust hood. It shall identify use of a portable fire extinguisher as secondary backup protection. SUBSTANTIATION: The use of a portable extinguishe r before activation of the fixed automatic system in a cooking grease fire could create a greater hazard since the fuel to the appliance will not be automatically shut down. This placard is necessary to communicate the need to activate the system before using the

ortable extinguisher. OMMITTEE ACTION: Accept in Principle. Revise to read as follows: 2-3.2.1 A placard shall be conspicuously placed near the

"Each fire ext inguisher shall have a tag or label securely a t tached that indicates the m o n t h and year. The ma i n t enance was pe r fo rmed and tha t identifies the person pe r fo rming the service. An electronic record keep ing system (i.e. bar coding) may be used in lieu of tag or label providing that the system chosen includes the same informat ion? ' S U B S T A N T I A T I O N : We are a large Heal thcare Inst i tut ion a n d use an electronic bar ccde system for inspect ions and annua l ma in t enance . This system provides a file for each ext inguisher and permi ts record ing ex t inguisher weight. T h e Federal agency HCVA will no t accept the electronic record because NFPA 10, 4.4.3 asks for a tag or label. Install ing a n d chang ing tags is a t ime consuming and costly opera t ion that in itself does no t keep files updated . A sample repor t f rom Loyola's bar code system was included.

Note: Suppor t ing material is available for review at NFPA Headqua r t e r s . COMMITTEE ACTION: Accept in Principle.

Add the following at the end ofA-4-4.3: "As stated in Section 1.-2 of this s tandard , no t h i ng in this s tandard

shall be cons t rued as a ~:estriction on new technologies or alternative a r rangements , provided tha t the level of protect ion as here in descr ibed is no t towered and is acceptable to the author i ty having jur isdict ion.

(Log #91) 10- 93 - (4-4.3.1.1): Accept SUBMITTER: Ernest E. Horvath, Reliable Fire Equipment Co., TG on Internal Maintenance RECOMMENDATION: Delete NFPA 10 Portable Fire Extinguishers 1994 Edition Errata. SUBSTANTIATION: The concept of an "internal legible marking" to indicate that a 6 year internal maintenance was ~erformed has no t been very effective. It requires the authority

avingjurisdict ion to depressurize and empty a fire extinguisher to verify if the 6 year internal maintenance was per formed plus refilling and pressurizing the fire extinguisher. Very few authorities having jurisdiction have the equipment necessary to perform this procedure, consequently, the verification of 6 year internal maintenance is rarely pe r fo rmed .

If a label is used for the "internal legible marking" on the syphon tube, the label must be "component-l is ted for that purpose". No labels have been submit ted to a testing laboratory. Therefore, many of the distributors who use a label are in violation of the NFPA 10 standard. COMMITTEE ACTION: Accept. COMMITTEE STATEMENT: See Commit tee Action on Proposal 10-94 (Log #92) for replacement text.

(Log #92) 10- 94 - (4-4.3.3 (New)): Accept in Principle SUBMITTER: Ernest E. Horvath, Reliable Fire Equipment Co., TG on Internal Maintenance RECOMMENDATION: Add the following new text:

4-4.3.2 Verification of Service (Maintenance or Recharging). Each extinguisher that has undergone maintenance which includes internal examination or that has been recharged (see 4-5.5) shall have a ' 'verification of Service" collar located a round the neck of die container. The collar shall contain a single circular piece of un in ter rupted material f o r m i n g a hole of a size that will no t permit collar assembly a round the neck of the container unless the valve is completely removed. The collar shall no t interfere with the operation of the fire extinguisher. The ' 'verification of Service" collar shall include the following information:

i a) Month and year die service was per formed indicated by a I perforation such as by a hand punch.

b) Name of agency performing the service. I Exception No. 1: Fire extinguishers undergoing maintenance

before (date to be de t e rmined ) Exception No. 2: Cartr idge/cyl inder-operated fire extinguishers

do not require a verification of service collar. SUBSTANTIATION: The concept of the external "Verification of Service" (Maintenance or Recharging) collar is a significant improvement over the internal tag or marking.

Since 1979, state fire marshals have seen the need to combat the "rag and tag" m e thod of service and provide a positive me thod to prove that a fire extinguisher valve had been removed and the shell given an internal examination. For this purpose , a label affixed to the s iphon tube of s tored pressure dry chemical fire extinguishers was the preferred me thod for service agencies to prove and for the authority having jurisdict ion to enforce the internal examination port ion of the six-year maintenance.

The 1994 edit ion of NFPA 10 was the first step to make national what was being done in many states by adding the requ i rement for an internal marking on the s iphon tube. As an alternative, the internal marking could be made on a self-adhesive label affixed to the s iphon tube. However, without any means in place to test and prove that a label material was capable of remaining at tached to the s iphon tube, concerns were expressed that inferior quality labels could become de tached inside the fire extinguisher shell with the potential for blocking the flow of dry chemical agent during discharge in the course of f ighting a fire.

One alternative is to provide an equally effective, externally located, means of proving that the extinguisher has rece ived the Pthroper internal examination dur ing the six-year procedure. Like

e internal maintenance label the "Verification Of Service" (Maintenance or Recharging) collar was des igned to accompany and verify die information that is recorded on the six-year maintenance label affixed to the shell. This collar can only be at tached when the valve is completely removed f rom the fire extinguisher shell. COMMITTEE ACTION: Accept in Principle.

[ Add text without item (b) (Exceptions to remain).

COMMITTEE STATEMENT: For small companies, a requi rement to include the name of agency performing the service might be an unnecessary expense. Other service tags provide this information.

4-5.5 Recharge Recordkeeping. Each fire extinguisher shall have a tag or label securely attached that indicates the month and year recharging was performed and that identifies the person performing the service. A Werification of Service' (Maintenance or Recharging) collar in accordance with paragraph 4-4.3.2 shall also be attached to the extinguisher.

Exception: Liquefied Gas, Halogenated Agent, and Carbon Dioxide extinguishers which havebeen recharge without valve removal and cartridge operated fire extinguishers are not required to have an existing Werification of Service" (Maintenance or Recharging) collar containing the last date of maintenance, replaced by a new collar containing the date recharging was performed.

SUBSTANTIATION: A "Verification of Service" (Maintenance or Recharging) collar is required as part of the recharging recordkeeping.

Fraudulent recharging o.f fire extinguishers by unscrupulous fire equipment companies currently is undetected. They charge their clients for recharging fire extinguishers even though the fire extinguishers were in operating condition at the time of annual maintenance. Fire inspectors are aware of the fraudulent service being performed by many fire equipment companies. The general public, quite ofte~ is not capable of evaluating a fire equipment company's professionalism and integrity. The "Verification of Service" collar can only be attached when the valve is completely removed from the fire extinguisher shell. This is a viable means of proving that a fire extinguisher was recharged and mitigates a common fraudulent practice by dishonest fire equipment companies. COMMITTEE ACTION: Accept.

A-4-4.3.2 "Verification of Service" (Maintenanceor Recharging) collar

A number of states have regulations requiring an internal marking of an extinguisher which is used to verify if the extinguisher was depressurized, the valve was removed and a complete maintenance was performed. The ''Verification of Service" collar design also requires that the valve be removed before the collar can be attached to the extinguisher. The collar provides the Authorities Having Jurisdiction with a more convenient visual proof that the extinguisher was disassembled and maintenance was performed.

This standard does not specifically require a "verification of Service" collar when a hydrostatic test is performed on a fire extinguisher cylinder. All extinguishers must have the valve removed for hydrotesting and must be subsequently recharged before returned to service. To be valid, the date on the ''verification of Service: collar must always be the same or more recent than the date on the hydrotest label.

C-3.5.X The trifluoroiodomethane (Triodide TM) extinguisher has an agent that is similar to Haion 1211 in that it is suitable for cold weather installation and leaves no residue. Trifluoroiodomethane (Triodide TM) is at least as effective as Halon 1211 on a weight-of- agent basis. When discharged, the agent is dispelled in a gas/mist form with about the same throw range as Haion 1211. To some extent, windy conditions or strong air currents may make extinguishment difficult by causing the rapid dispersal of the agent. SUBSTANTIATION: Triodide TM has been listed as an acceptable streaming agent for replacement of Halons 1211 and 1301 under the Significant New Alternatives Policy (SNAP) Program (Federal Register, Vol. 61 No. 1OO, Wednesday, May 22, 1996, pp. 25585- 25594) and is being commercialized for this purpose.

Larger models of Halocarbon fire extinguishers are listed for class A as well as class B and class C fires which makes them quite suitable for use on fires in electronic equipment. Compared to carbon dioxide on a weight of agent basis, Halocarbon agents are at least twice as effective. When discharged the agent is in a combined form of a gas/mist with about twice the range of carbon dioxide. To some extent, windy conditions or strong air currents may make extinguishing difficult by causing a rapid dispersal of agent.

These fire extinguishers have ratings of 1 B:C and 2A:I- B:C, respectively and also have been found suitable for Class K hazards. The extinguishing agent is a solution of water and potassium acetate, potassium carbonate, potassium citrate, or a combination of the aforementioned chemicals. The liquid agent typically has a p H of 9.0 or less. On Glass A fires the agent works as a coolant. On Class K fires (cooking oil fires), the agent forms

I a foam blanket to prevent reignition The water content of the i agent aids in cooling and reducing the temnerature of the hot oils I and fats below their auto ignition point. Tl~e agent is discharged as a fine spray which reduces the possibility of splashing hot grease.

In recent years the development of high efficiency cooking equipment with high energy input rates and the under spread use of vegetable oils with high auto ignition temperatures highlighted the need for a new Glass K fire. The wet chemical extinguisher was the first extinguisher to qualify to the new Class K requirements.

In addition to offering rapid fire extinguishment, a thick foam blanket is formed to prevent reignition while cooling both the appliance and the hot cooking oil. Wet chemical extinguishers also offer improved visibility during fire fighting as well as

minimizing clean-up afterwards.

D-4.2.1 AFFF and FFFP. Fire extinguishers of this type are usually available in hand portable models of 6 liter and 2 1/2 gal (9.46-L) and in wheeled models having a liquid capacity of 33 gal (125 L). These fire extinguishers have ratings of 2A:10-B, 3-A~20B, and 20- A:160-B, respectively. The extinguishing agent is a solution of film forming surfactant in water that forms mechanical foam when discharged through an aspirating nozzle. On Class A fires, the agent acts as both a coolant andpenet ran t to reduce temperatures to below the ignition level. On Class B fires, the agent acts as a barrier to exclude air or oxygen from the fuel surface.

Grades of these agents are also suitable for the protection of water-soluble flammable liquids (polar solvents) such as alcohols, acetone, esters, ketones, etc. The suitability of these fire extinguishers for polar solvent fires must be specifically referenced on the nameplate. These agents are not suitable for use on pressurized fuel fires or cooking grease fires.

Specific information on the properties and limitations of AFFF and FFFP are contained in NFPA 11, Standard for Low-Expansion Foam.

The hand portable models closely resemble stored-pressure water fire extinguishers except for the special types of nozzles. [See Figure D-4.2.1 (a)]. Wheeled types are operated by a separate nitrogen cylinder containing the expellent gas which, when released, pressurized the agent container. The discharge is controlledby a special aspirating shut-off type of nozzle at the end of the hose assembly. These types of fire extinguishers can be used only in locations not subject to freezing conditions unless special measures areprovided to prevent the agent from freezing as recommendedby the manufacturer.

Although the liquid is retained under pressure in a liquid state and is self-expelling, a booster charge of nilxogen is added to ensure proper operation. Upon actuation, the vapor pressure causes the agent to expand so that the discharge stream consists of a mixture of liquid droplets and vapor. The smaller sizes have horizontal stream range of 9 to 15 ft (~.7 to 4.6 m) that is not affected by wind as much as carbon dioxide or Halon 1301o Deep-seated Class A fires need to be broken apart to effect complete extinguishment. On Class B fires, the discharge is applied in a side-to-side motion gradually progressing towards the back of the fire. The fire extinguisher should be discharged initially from not closer than 8 ft (2.4 m) to prevent splashing when applied to depths of flammable liquid.

"Class B Fires Fires in flammable liquids and flammable gases. Examples of

flammable liquids are grease, gasoline, paint, solvents, fuel oil and kerosene. Examples of flammable gases are acetylene, natural gas (methane), propane and butane." SUBSTANTIATION: Ewe make mention in the definition of Class B fires, that it includes flammable gases. The examples cited above can surely be found in many homes/residential settings. I think that it would be prudent if we maintained a continuity with the definition that appears in Section 1-3 of NFPA 101L COMMITTEE ACTION: Reject. COMMITTEE STATEMENT: Although technically Class B fires could include flammable gases, the Committee feels this type of fire takes special knowledge and skills, and therefore hesitates to add it to this example.

A-3-2.1 Experience indicates that most dwelling fires start in the living room and kitchen. Thus, at least once extinguisher should be located where it can be quickly reached from both of these rooms. It is best to locate each extinguisher near the path of exit travel so that if the fire cannot be readily controlled with the device, a quick escape can be made. In bedrooms, the extinguisher should be located in a convenient handy closet or cabineL In basements, the top of the basement stairs is preferred except when a basement workshop may dictate otherwise. It is important that the location of each extinguisher be known to each member of the family who is able to use the device. A permanently mounted bracket on which to hang the extinguisher will help to ensure that it remains is place and is not tucked away in a closet or other place which may be difficult to reach."
