3.3 Miscellaneous Fire Suppression Flashcards
If class A foam is used on a flammable liquid fire, what needs to be pout in place ASAP and what needs to be communicated?
Class B hoseline and that class A foam is being used
On a working vehicle fire, the Incident Commander (IC) ensures the following:
. Attack crews wear full personal protective equipment, including self-contained breathing apparatus.
b. Attack line(s) should be at least 1¾-inch in size.
c. Vehicles are stabilized.
d. A patent water supply and other extinguishing agents are available as needed.
e. Run-off fuel and/or contaminated water is accounted for and their effects minimized.
During size-up for these dumpster fires, consideration should be given to:
a. hazardous, toxic and/or reactive materials
b. occupancy of nearby structures and associated use
c. possible exposures
d. upwind approach
e. possible containment of run-off
What must be worn for dumpster fires?
Full PPE, including SCBA
After a dumpster fire, 2 things should happen:
- Investigation if necessary
2. RP contacted if possible
When CO levels above 15 parts per million (PPM) are detected:
Captain should ask 100 to call the appropriate utility company to respond. The crew should evacuate occupants and don SCBA before further investigation
When CO is present and the utility company has an extended response time the Captain may decide to go available on scene or clear the scene. Some requirements should be met before we go available:
a. The source of the CO has been found or limited to an appliance
b. The utility company is responding with an ETA
c. A peak level of CO has been found
d. Mitigate the leak and ensure levels are dropping
e. RP has been informed of hazards of CO
f. RP has a safe/warm place to wait for the utility company
g. RP contact information has been gathered
h. The Captain follows up with RP to make sure the utility company has mitigated the issue
Engines with a standard hose bed shall carry the following hose complements:
- 800 feet of 5-inch supply hose. The top 100 feet (first to deploy) is two 50-foot sections of high-pressure (green) hose.
- 800 feet (minimum) of 3-inch supply hose
- 300 feet of 2.5-inch hand line
- 400 feet of 1.75-inch hand line
- 200 feet (2x100 feet) of 1.75-inch high-rise hose
- 100 to 200 feet of selected hose in the bumper compartment
- 200 feet of booster line
- 1 short section (25 feet) of 5-inch supply hose
- 1 short section (25 feet) of 2.5-inch supply hose
- 2 short sections of 3-inch hose attached to the 5-inch wye
The standard hose load configuration shall be (looking from the back of the engine):
- The far left hose compartment is 200 feet of 1.75 inch hand line. Bottom 100’ is to be in a flat load configuration with two dump loops. The top 100’ is to be loaded in a minuteman configuration that is < 7’ in length and tied with 6mm cordage and fitted with a TFT dual pressure automatic fog nozzle.
- The compartment second from left is 800 feet of 5-inch supply hose, loaded in a flat configuration. A 5-inch hydrant/swivel adapter is attached to the top section in the hose bed.
- The compartment third from left is a minimum of 400 feet of 3-inch supply hose in a flat configuration with the top 100 feet in a minuteman configuration. The hose is loaded in a reverse manner (male coupling on top). Begin the load with the female end extended beyond the rear of the hose bed from the far right side of the third bed. End the load with the male coupling on top.
- The compartment fourth from left is a minimum of 400 feet of 3-inch supply hose in a flat configuration. The hose is loaded in a reverse manner (male coupling on top). The top male coupling is connected to the female coupling at the base of the third compartment. The loads carried in hose compartments three and four make up double reverse loads. This arrangement allows for a long reverse lay in an interface or rural situation or allows the load to be split to supply dual lines for automatic sprinkler/standpipe connections, appliances or other engines.
- The compartment fifth from the left is 300 feet of 2 ½” hose. Bottom 100’ is to be loaded in a flat configuration with one dump loop with the male coupling at the rear (back of the engine) of the hose bed. Middle 100’ is to be loaded with the first female coupling exposed and creating a dump loop so it can be either connected to the outlet or used as a dump loop. The top 100’ is to be loaded in a minuteman configuration that is < 7’ in length and tied with 6mm cordage and fitted with a smooth bore nozzle with a stacked tip including 1 1/8” and 1 ¼”.
- The far right hose compartment is 200 feet of 1.75 inch hand line. Bottom 100’ is to be in a flat load configuration with two dump loops. The top 100’ is to be loaded in a minuteman configuration that is < 7’ in length and tied with 6mm cordage and fitted with a TFT dual pressure automatic fog nozzle.
Max length of bumper line:
100 feet
Bumper line shall be used for _____ ops only
Exterior
The type and amount of hose stored in the station for re-supply should include the following:
- 400 feet of 3-inch supply house
- 300 feet of 2.5-inch hose
- 400 feet of 1.75-inch pre-connect hose
- 200 feet of 1.75-inch high-rise hose
The rule of thumb on single engine aircraft crash response is to:
Only fight the fire that interferes with the rescue
Size-up for single engine aircraft crash should include an evaluation of the following conditions:
- Determine whether buildings, vehicles, power lines, or people are involved, extraneous to the aircraft itself
- Determine if it is safe to approach the aircraft –propeller rotation has stopped
- Determine whether rescue or a recovery of patients is needed
- The amount of fuel that is (or may) be on fire
- Size of the area involved (debris field)
Strategic Considerations for single engine aircraft crash:
- Rescue vs. Recovery operation
- Offensive or defensive operations for fire attack
- Apparatus placement considerations often include; space for extrication equipment, placement of Foam 10 for adequate reach with foam streams, and wind direction
