Building Construction
How many classes of building construction does the fire service use?
5
DOT Placard 1075
LPG (Liquified Petroleum Gas such as Propane or Butane)
What types of materials do Class B fires involve?
Combustible liquids and gases
Applying water to a fire is an example of what type of extinguishment method:
Temperature Reduction (cooling)
The RIC/UAC on the RIT PAK is the preferred method of air transfer to a firefighter in distress, who is still breathing. True of False?
True
Trusses, I-Joists, and laminated beams are all components of this form of wood construction
Lightweight Construction
With a vapor density of 1.55 propane will settle or rise?
Settle, heavier than vapor density of air (1.00)
Class C fires involve:
Energized electrical equipment
Directing short bursts of water into the hot gas layer will do what?
will cool the gas layer and reduce chances of the gases igniting.
When the contents of a room reach a certain temperature and spontaneously combust, resulting in extreme, unsurvivable, heat.
Flashover
This construction type has exterior walls and structural features made of non-combustible materials, usually masonry, or limited combustible materials. The roof, interior walls, floors and ceiling can be constructed of wood.
Type 3 (Ordinary Construction)
A responder at the Hazardous Materials Operation level can take some action to contain a spill. This can include absorption, and these three methods of containment.
Damming, Diking, and Diverting
What is the PASS method stand for?
Pull the pin, Aim the hose/nozzle, Squeeze the nozzle, Sweep at the base of the fire.
What is a transitional attack?
Water is applied from the exterior first to transition the fire from ventilation-limited to fuel-limited
Assign the tip sizes of the smoothbore nozzle stack tip for the 2.5" handline with the appropriate gallons per minute
1"-approx. 200 GPM
1 1/8"-approx. 250 GPM
1 1/4"-approx. 300 GPM
A major difference between fire-resistive construction and noncombustible construction is...
...in fire resistive construction, the structural steel must be protected from the fire's heat.
What are the four gases monitored on Company 2's 4 gas meter?
Oxygen
Carbon Monoxide
Hydrogen Sulfide
Lower Explosive Limit (pentane, combustible gases)
A water can extinguisher carries this much water when properly filled
2.5 gallons
Notches or grooves cut into hose coupling lugs to identify by touch or sight the exact location of the thread starting point is referred to by this name.
Higbee cut or indicator
The three methods of heat transfer (in order)
1) Transfer of heat through and between solids 2) Transfer of thermal energy by circulation of liquid or gases 3)Transmission of energy as an electromagnetic wave
Conduction, Convection, Radiation
What is the main difference between platform and balloon framing?
Exterior wall studs are constructed with one continuous piece of lumber.
Recent DEEP Guidance only wants a fire department to notify them of leaks resulting from routine motor vehicle accidents only when the leak exceeds this many gallons
5 gallons
Extinguishers filled with monoammonium phosphate, (also known as multi-purpose dry chemical). are used for these classes of fire
ABC
The tip diameter of a smoothbore nozzle for a 1.75" hardline is
15/16"
When all the water carried on all Co.2 apparatus’ booster tanks is tallied up it equals this number of gallons?
3,280 gallons
Engine 6-1,000 gallons
Tanker 5-2,000 gallons
Brush- 200 gallons
Ranger- 80 gallons
