check in with IC for verification of assignments and perform safety officer duties.
what shall the safety officer do with his grace accountability box?
bring the accountability base and a t pass repeater to crew staging if established for a spare. if crew staging is not established leave the grace accountability base with lobby control for future deployment.
who shall establish crew staging and where shall it be established?
the company designated by IC shall be responsible for establishing crew staging two floors below the fire. it may be necessary to locate crew staging on a lower floor due to smoke or availability of space.
what is the minimum number of reserve companies that should be in crew staging?
the level of reserve companies maintained by the crew staging officer should be at least one company for every company engaged on the fire floor. the optimal number should be 2 companies per company engaged.
where should reserve companies be requested from?
the resource group will work under who?
the resource group will be under the direction of the lobby control
who does the resource group communicate with when requesting additional equipment?
the lobby control
who will clear the elevators at lobby level before being used?
lobby control and the fire attack group
who will approve the use of elevators?
describe the process of use of the elevator by the fire attack group?
fire attack group along with lobby will clear the elevator before use.
firefighters will proceed to the fifth floor below the fire.
if the elevator functions properly then firefighters may proceed to the second floor below the fire.
what needs to be done if the elevator fails to stop at the fifth floor below the fire?
the elevator emergency stop/run switch or key will utilized to stop the elevator. as a last resort use any necessary means to stop the elevator, such as opening the inner car doors.
what should be done if firefighters find themselves locked in an elevator at lobby level?
utilize the pull station which should unlock the elevator lobby doors.
what is the preferred method in supplying the fdc?
the preferred method is to use one high pressure engine to supply the fdc
how should a fdc be supplied if a high pressure pumper is not immediately available?
a two engine tandem pump operation will be established to supply the fdc.
what is the procedure for supplying the fdc with a high pressure pumper
connect dual 3" lines to fdc and lay to a safe location near a hydrant
a second engine will hook up to the hydrant and supply the high pressure engine through dual 4" lines
what is the procedure for supplying the fdc with a two engine tandem pump?
one engine will connect dual 3" linesto the fdc and lay to a safe location near a hydrant
a 2nd engine will hook up to the hydrant and supply the 1st engine through nore than 100ft of dual 4" lines
the supply engine will pump 250 psi into the high pressure engine. the supply engine must cap the discharge relief valve
what must the supply engine cap when pumping 250 psi into the high pressure engine?
the supply engine must cap the 4 " discharge relief valve.
