Flashcards in ECH Chapter 4-6 Deck (21):
The company officer’s responsibilities at a structure fire can be broken into the three basic phases, what are they?
Responding to, on arrival, and suppression.
The officer has several options for securing a water supply, name 6
1) tank water; 2) lay-in wet; 3) lay-in dry; 4) lay-out; 5) split lay; 6) hand-jack.
S- Size of building H- Height of building O- Occupancy type C- Conditions of the fire K- Kinds of actions being taken E- Exposures R- Resources needed
The engineer has three basic responsibilities during fire operations
delivering the crew and apparatus safely to the scene; pumping operations; and securing a water supply
The engineer of an engine company has five means of water supply connection
5" supply line laid from the hose bed; a 30-foot 5" supply line with Storz couplings; a 50-foot 5" supply line with Storz couplings; two 30foot pre-connected 3" hose “shorties” with 2½" couplings; and a 10-foot hard suction length
While responding to a fire, what is the one key piece of information the nozzle FF should be concerned about?
What are the 3 phases of firefighting?
Phase 1—Locate the fire; Phase 2—Confine the fire (head it off and surround it); Phase 3—Extinguish the fire.
What are the 3 fire attack methods
Indirect, direct, and combination
How many lines can an engine company effectively stretch?
When life safety is not a factor, then the first hose line is placed.....
between the fire and the most severe exposure
What are the 3 fundamentals that must be followed every time a hose line is stretched?
1. Determine the location of the fire
2.Determine the hose size
3.Estimate the amount of hose needed
NFPA Standard on Training for Initial Emergency Scene Operations
NFPA Standard for the Organization and Deployment of Fire Suppression Operations, Emergency Medical Operations, and Special Operations to the Public by Career Fire Departments
A. Advanced fire conditions on arrival D. Defensive operations U. Unable to determine seat or location of the fire L. Large, uncompartmentalized area (supermarket, tilt-up, warehouse, etc.) T. “Tons of water.” Any time you need to deliver 250 gpm or more. S. Standpipe operations
The general rule for estimating the number of lengths in a fire building is:
1 length for setback (engine to front door) • 1 length per floor (interior stairwell) • 1 length for the fire floor (50' or working line at door) • 1 length per three floors (exterior or well-hole stretch) • 1 length per residential property line to property line width
What is the most important decision that the engine company officer will make after determining the location of the fire?
Where should the two out line be stretched to?
How much working line should you have at the front door for a 1 ¾”, a 2 ½”?
If it is determined there is no life hazard in the building, the first hose line should be positioned between the fire and the
Most severe exposure
Department SOGs allow the advancement of the 2OUT hose line in situations where:
An additional attack hose line is needed. • Pressure loss to the attack hose line is experienced. • Nozzle team is trapped by fire. • Truck company members’ egress is cut off.
