Fire Alarms

1. The ICS was developed so that each person has only one supervisor, eliminating the confusion that can result when you are given orders from more than one boss. It also ensures that every member on the emergency scene is accounted for. Notify the Division D supervisor that you are assigned to Division C. (page 837)

2. When the fire is too large or too dangerous to extinguish with an offensive attack, the IC will implement a defensive strategy. A defensive strategy is required when the IC determines that the risk to fire fighters’ lives is excessive, as in situations where structural collapse is possible. The IC who adopts a defensive strategy has determined that there is no property left to save or that the potential for saving property does not justify the risk to fire fighters. (page 845)

1. Class A foam increases the effectiveness of water as an extinguishing agent by reducing the surface tension of water. This allows the water to penetrate dense materials instead of running off the surface and allows more heat to be absorbed. Class B foam extinguishes f lammable-liquid fires by separating the fuel from the fire. When a blanker of foam completely covers the surface of the liquid, the release of f lammable vapors stops. (page 869)

2. The indicators of a possible building collapse include (student should identify 5): (1) visible indication of sagging f loors or roof supports, (2) indication that the roof assembly is separating from the walls, such as the appearance of fire of smoke near the roof edges, (3) cracked, crumbing, or bulging walls, (4) smoke or water coming through masonry walls, (5) structural failure of any portion of the building, even if it is some distance from the fire fighters, (6) heavy fire conditions below any interior operation, (7) sudden increase in the intensity of the fire from the roof opening, (8) high heat indicators on a thermal imaging camera. (page 858)

3. Class A foams are usually formulated to be mixed with water in ratios from 0.1 percent (1 gallon of concentrate to 999 gallons of water, or 1 liter of concentrate to 999 liters of water) to 1 percent (1 gallon of concentrate to 99 gallons of water, or 1 liter of concentrate to 99 liters of water).

varying the percentage of foam concentrate in the mixture and the application method. It is possible to produce “wet” foam that has good penetrating properties, for example, or “drier” foam that is more effective for applying a protective layer of foam onto a building. (page 870)

4. S.L.I.C.E.-R.S. is an acronym that was developed as a tool to assist fire fighters and officers during scene size-up. The seven components stand for; S – size up, gather and analyze information to help develop the IAP, L – locate the fire, determine the location and extent of the fire inside a building, I – identify and control the f low path, if possible, C – cool the space from the safest location, E – extinguish the fire fully, including overhaul of void spaces, R – rescue, conduct search and rescue operations as indicated by a risk/benefit analysis, S – salvage – protect property from further damage. (page 859)

5. The five major categories of Class B foam are; (1) protein foam, (2) f luoroprotein foam, (3) film-forming f luoroprotein foam, (4) aqueous film-forming foam (AFFF), (5) alcohol-resistant foam. (page 871)

Fire Alarms

1. Ensure that the integrity of the cylinder has been inspected from a distance before making an attempt to approach and close the discharge valve. If the container is damaged or the discharge valve is missing, the fuel should be allowed to burn off, while hose streams continue to cool the tank from a distance. Approach a f lammable gas fire with two 1 ¾-in. (45-mm) hose lines working together. When approaching, always approach from the sides using a straight stream to cool the tank from a distance. Carefully approach the tank while continuing to adjust the nozzle to a wide fog pattern. The officer/team leader should be located between the two nozzle operators. On the command of the officer, the crew should move forward, remaining together at all times. Upon reaching the discharge valve, the fire fighter in the center can close the discharge valve, stopping the f low of gas. Any remaining fire may then be extinguished by normal means. Continue the f low of water as a protective curtain and to reduce sources of ignition. If the fire is extinguished prematurely, the discharge valve should be closed as soon as the team reaches it. Always approach and retreat with water f lowing, in case of reignition. (page 865)

2. Perform this technique by directing the foam steam onto the ground in front of the product involved. The stream is moved back and forth is a slow, steady horizontal motion to push the foam gently until the area is covered. It is important to push the foam slowly and gently so that the foam blanket is not disturbed. Avoid aiming the nozzle down toward the surface of the spill to prevent splashing fuel. You may need to move to different positions to ensure that the entire surface of the fuel is covered by the foam blanket. (page 876)

3. Gradually adjust the nozzles to a wide fog pattern as you approach the side of the tank. Make sure the fog streams overlap as you reach the tank.

5. After the burning gas is extinguished, the fire fighters continue to apply water to the cylinder to cool the metal, with the goal of preventing tank failure and a subsequent BLEVE.

4. When the cylinder is reached, the two nozzle teams isolate the discharge valve from the fire with their fog streams while the leader closes the discharge valve, eliminating the fuel source.

6. As cooling continues, fire fighters slowly back

away from the cylinder while adjusting the nozzles to a straight stream as they retreat. (page 867)

Skill Drill 23-3: Operating an In-Line Foam Eductor Fire Fighter II, NFPA 1001: 5.3.1 Test your knowledge of this skill drill by filling in the correct words in the photo captions.

1. Don all PPE. Make sure all necessary equipment is available, including an in-line foam eductor and the correct

nozzle. Ensure that enough foam concentrate is available to suppress the fire. Deploy an attack line, remove the nozzle, and replace it with the foam nozzle.

2. Place the foam concentrate container next to the eductor, check the percentage at which the foam concentrate should be used (found on container label), and set the metering device on the eductor accordingly.

3. Place the in-line eductor in the hose line according to the manufacturer’s instructions and your department’s SOPs.

4. Place the pickup tube from the eductor into the foam concentrate, keeping both items at similar elevations to ensure sufficient induction of foam concentrate. Charge the hose line with water per your department SOPs or as directed by the manufacturer.

5. Flow water through the hose line until foam starts to come out of the nozzle. The hose line is now ready to be advanced onto the fuel. Apply foam using one of the three application methods (roll-in method, bounce-off method, or rain-down method) depending on the situation. (page 874)

Skill Drill 23-7: Performing an Annual Service Test on a Fire Hose Fire Fighter II, NFPA 1001: 5.5.5 Test your knowledge of this skill drill by placing the photos below in the correct order. Number the first step with a “1,” the second step with a “2,” and so on.

1. Don turnout gear. Connect up to 300 ft (91 m) of hose to a hose test gate valve on the discharge valve of a fire department pumper or hose tester.

3. Open the nozzles to purge air from the hose, discharging the water away from the test area. Close the nozzles once the air is purged. Measure and record the length of each section of hose.

2. Attach a nozzle to the end of each hose. Slowly fill each hose with water at 50 psi (345 kPa), and remove kinks and twists in the hose.

4. Mark the position of each hose coupling on the

hose. This will help determine if slippage occurs during the test (Step 7). Check each coupling for leaks. If leaks are found behind the coupling, remove the hose from service. If the leak is in front of the coupling, tighten the leaking coupling. If the leak continues, replace gaskets if necessary after shutting down the hose line.

5. Close each hose test gate valve.

1. The four general functions of gaining access and disentangling a victim are: (1) Stabilize or hold an object or vehicle: An example is stabilizing a vehicle with cribbing to keep it from moving. (2) Bend, distort, or displace: An example is bending a vehicle door back to get it out of the way. (3) Cut or sever: An example is cutting a roof. (4) Disassemble: An example is removing a vehicle door by unbolting the door hinges. (page 908)

2. The five types of alternative-fuel vehicles include: (1) battery electric vehicles, which use an electric motor only; (2) hybrid electric vehicles, which use both a battery-powered electric motor and a liquid-fueled engine; (3) blended liquid fuel-powered vehicles, which use a blend of liquid fuels such as gasoline and methanol or ethanol; (4) compressed gas-powered vehicles, which use one of three types of compressed gas, CNG, LNG, or LPG; (5) fuel cell–powered vehicles, which use fuel cells to generate electricity through a chemical reaction. (page 890)

3. Safety tips for using rescue-lift air bags include the following (Students should list five of the following): (1) Never stack high-pressure lift air bags more than two high. (2) Do not use a rescue-lift air bag to pull a steering column. (3) Do not use a rescue-lift air bag as the sole means to stabilize a vehicle; cribbing must be the primary stabilizer. (4) Never operate the rescue-lift air bag system without having been properly trained and fully understanding how the system works. (5) When stacking rescue-lift air bags, the largest size should be on the bottom and the smallest on top. The bottom rescue-lift air bag should be inf lated first. (6) Place a sheet of plywood or other protective material on the ground under the air bag to protect it. (7) Refer to your department SOPs and the manufacturer’s instructions on proper use. (8) Clean rescue-lift air bags by following the recommendations of the manufacturer. (9) Test rescue-lift air bags regularly. (10) Never store a lift air bag near gasoline. (page 900)

Fire Alarms

1a. Protecting the scene from approaching traffic: Whenever possible, place emergency vehicles in a manner that will ensure safety and does not disrupt traffic any more than necessary. However, do not hesitate to request that the road be closed if necessary. Remember: Safety first! Position large emergency vehicles so that they provide a barrier against motorists who fail to heed emergency warning lights. Many departments place apparatus at an angle to the crash. This position helps to push the apparatus to the side of a crash in the event that the emergency apparatus is struck from behind. Traffic cones or flares can be placed to direct motorists away from the crash. If needed, call for law enforcement to assist in traffic control. Fire fighters need to be readily visible at a crash scene. Personal protective equipment (PPE) must be worn at all MVAs. Unless you are exposed to or are likely to be exposed to fire conditions, you must wear a high-visibility safety vest that is compliant with the appropriate standards.

1b. Scene size-up: (1) Position the emergency vehicle so as to protect the scene and take any additional actions needed to prevent further MVAs. (2) Perform a quick initial assessment as you arrive on scene, establish command, and give a brief initial radio report. (3) Establish fire suppression protection. (4) Perform a 360-degree walk-around to identify potential hazards; look for hazards above and below the vehicle and determine the stabilization equipment needed to prevent further movement of the vehicle(s) involved in the accident. (5) Determine the number of patients, the severity of their injuries, and the amount of entrapment. (6) Give an updated report and call for additional resources if needed. (7) Establish a secure working area and equipment staging area. (8) Direct personnel to perform initial tasks. (pages 892–895)

2a. Equipment to use for vehicle stabilization: (1) Cribbing; (2) Step chocks; (3) Wedges; (4) Rescue-lift air bags 2b. Steps to stabilize the vehicles: (1) Don PPE. (2) Chock both sides of one tire to prevent the vehicle from rolling. (3) Use

additional step chocks and cribbing as needed. (4) Consider def lating the tires for added stability. (5) Place the gear shift in park and apply the parking brake. (6) Lower all automatic windows if possible. (7) Turn off the ignition and remove the key or fob. (pages 897–900)

Skill Drill 24-1: Disable the Electrical System of an Electric Drive Vehicle Fire Fighter II, NFPA 1001: 5.4.1 Test your knowledge of this skill drill by filling in the correct words in the photo captions.

1. Immobilize the vehicle by chocking the wheels. Set the parking brake, and place the vehicle in park, if you can

access these controls.

2. Lower all automatic windows, if possible. Disable the low-voltage system by shutting off the vehicle’s ignition (power button or conventional key) and disconnecting or cutting the 12-volt battery cables. Cut the 12-volt negative cable first, and then cut the positive cable. Double cut each cable to remove a short section. This will prevent the cables from accidentally touching. For vehicles equipped with a proximity key, move the key as far away from the vehicle as possible to prevent the possibility of unintentional restart. Because it may take up to 10 minutes for the high-voltage system to discharge, use caution while performing extrication operations. (page 891)

(page 921)

Fire Alarms

1. Safety is of paramount importance when approaching a trench or excavation collapse. Walking close to the edge of a collapse can trigger a secondary collapse, so stay away from the edge of the collapse and keep all workers and bystanders at a distance from the site. Vibration from equipment and machinery can also cause secondary collapses, so shut off all heavy equipment. Likewise, vibrations caused by nearby traffic can cause collapse, so it may be necessary to stop or divert traffic near the scene. Make verbal contact with the trapped person, if possible, but do not place yourself in danger while doing so. If you plan to approach the trench at all, do so from the narrow end where the soil will be more stable. It is best not to approach the trench unless absolutely necessary. Stay out of the trench unless you have been properly trained in trench rescue techniques. (page 939)

2. Respond safely to the emergency scene. Place the emergency vehicle in a safe position that protects the scene, parking at least one utility pole span away. Watch for falling utility poles. Perform a size-up to assess for hazards. Do not rush to assist victims who have come in contact with energized electrical equipment. Secure the scene and call for needed assistance. Don the appropriate personal protective equipment (PPE). Do not touch any wires until they have been de-energized by the power company. Use appropriate devices to establish a barrier, following the IC’s orders. (pages 928–929)

2. The three fire suppression systems are (1) automatic sprinkler systems, (2) standpipe systems, and (3) special hazard suppression systems. (page 970)

3. The four categories of sprinkler systems are (1) Wet sprinkler system: The piping in a wet system is always filled with water. When activated, water is immediately discharged; (2) Dry sprinkler system: The pipes are filled with pressurized air, which keeps water out until the air pressure is released. The system utilizes accelerators and exhausters; (3) Preaction sprinkler system: This system is similar to a dry sprinkler system except that a secondary device (pull alarm, smoke detector) must be activated before the water is released; and (4) Deluge sprinkler system: In this type of dry sprinkler system, all of the sprinkler heads are activated as soon as the system is activated. The sprinkler heads are always open. (pages 979–981)

4. The three categories of standpipes are (1) A Class I standpipe is designed for use by fire department personnel only. Each outlet has a 2½-inch (64-mm) male coupling and a valve to open the water supply after the attack line is connected. The connection is often located inside a cabinet, which may or may not be locked. Responding fire personnel carry the hose into the building with them, usually in some sort of roll, bag, or backpack. A Class I standpipe system must be able to supply an adequate volume of water with sufficient pressure to operate fire department attack lines. (2) A Class II standpipe is designed for use by the building occupants. The outlets are usually equipped with a length of 1½-inch (38-mm) single-jacket hose preconnected to the system. These systems are intended to enable occupants to attack a fire before the fire department arrives, but their safety and effectiveness are questionable. (3) A Class III standpipe has the features of both Class I and Class II standpipes in a single system. This kind of system has 2½-inch (64-mm) outlets for fire department use, as well as smaller outlets with attached hoses for occupant use. (pages 983–984)

5. The variations that are different in a residential sprinkler system compared to a commercial system include: (1) the primary objective of a residential system is to protect egress routes so occupants can evacuate safely; (2) quick response residential sprinkler heads are used; (3) smaller piping and sprinkler heads with smaller orifices that discharge less water are used; (4) plastic pipe may be used instead of metal pipe; (5) residential systems typically only protect high-risk areas; (6) usually only wet pipe systems are used; (7) there is no fire department connection (FDC); (8) they are not connected to a fire alarm system, unless required by the local jurisdiction. (page 982)

Fire Alarms

1. Carbon dioxide extinguishes a fire by displacing the oxygen and creates a dangerous situation. Fire fighters must use extreme caution as oxygen levels will be dangerously low. Full protective equipment (PPE) and SCBA are required. (page 989)

2. From a safety standpoint, fire fighters need to understand the operations and limitations of fire detection and suppression systems. A building with a fire protection system will have very different working conditions during a fire than an unprotected building will. Fire fighters need to know how to fight a fire in a building with a working fire suppression system, and how to shut down the system after the fire is extinguished. From a customer service standpoint, fire fighters who understand how fire protection systems work can help dispel misconceptions about these systems and advise building owners and occupants after an alarm is sounded.

(page 1046)

Fire Alarms

1. After the investigator identifies the area of origin, fire fighters could be asked to assist in digging out the fire scene. “Digging out” is a term used to describe the process of carefully looking for evidence within the debris. Sometimes the entire fire scene must be closely examined to determine the cause of the fire and gather evidence. The fire investigator will take extensive photographs of the fire scene as it first appears. He or she will then begin to remove and inspect the debris, layer by layer, working from the top of the pile down to the bottom. Removing and inspecting the layers of debris enable the investigator to determine in what order items burned, whether an item burned from the top down or from the bottom up, and how long it burned. Systematically digging through the debris often can uncover the exact point of origin and cause of both accidental and deliberate fires. The investigator will explain generally what to look for, how to search, and what to do with any potential evidence. (page 1045)

2. Take photographs of each piece of evidence as it is found and collected. If possible, photograph the item as it was found, before it is moved or disturbed. On the fire scene, sketch, mark, and label the location of the evidence. Place evidence in appropriate containers to ensure their safety and prevent contamination. Unused paint cans with lids that seal automatically when closed are the best containers for transporting evidence. Glass mason jars sealed with a sturdy sealing tape are appropriate for transporting smaller quantities of materials. Plastic containers or bags should not be used to hold evidence involving petroleum products. Soak up small quantities of liquids with either a cellulose sponge or cotton batting. Tag all evidence at the fire scene. The evidence container should be labeled with the date, time, location, and investigator’s name. Record the time the evidence was found, the location where it was found, and the name of the person who found it. Keep a record of each person who handled the evidence. Keep a constant watch on the evidence until it can be stored in a secure location. Evidence that must be moved temporarily should be put in a secure place accessible only to authorized personnel. Preserve the chain of custody in handling all the evidence. A broken chain of custody may result in a court ruling that the evidence is inadmissible. (page 1048)
