OPERATION basics
AO will put spreaders down where he wants equipment set up.
About 16’ from working area (32’ hoses).
Watch for high sign before dumping compartment. Start up and hook up tools we need. Stay on power units and wait for commands.
Cribbing and chock blocks NOT near posts we’ll be cutting.
Lift and sit down on cribbing.
Everyone’s jobs
Top/Inside: Empty compartment, monitor equipment
Tiller: Cribbing
Noz/Hyd: Pt care
CI: Triage MCI and/or oversee pt care
Engineer: 1.5” loaded line and dry chem (and monitor)
Rescue: MCI: open comms with hospitals to find open beds
CII: Incident Commander
SAFETY points
Full PPEs No axe Chock/crib before working Consider battery d/c if fuel leaking or airbags not deployed Apply Secunet if airbags not deployed Dry chem and 1.5” hand line (engineer) Stay out from between tool and vehicle
VEHICLE notes
Nader bolt: 5000lbs of force to cut, since 1981
Shoulder harness brackets: 3-4” square, located at roofline, avoid cutting here
Windshield is safety (laminated) glass; all others are tempered glass
Capacitors: some newer vehicles have back up power for up to 30mins.
Beware of gas struts flying off in fire conditions.
Batteries can be located anywhere.
MAINTENANCE daily
Check fuel, oil levels, starting positions, visueal check
MAINTENANCE weekly
Start and warm up (15 mins), attach tools and operate, check functions, check starter cords
