• EVALUATE when it is safe to fight an
“early-stage” vehicle fire, and;

Trash Truck fires usually
start in one of three places:
• CAB
– Electrical shorts under dash, often caused by
improperly installed (unauthorized ) accessories
– Discarded cigarettes igniting trash or upholstery
• ENGINE COMPARTMENT
– Fuel or oil system leaks onto hot engine
• Pre-trip inspection, and proper maintenance
• CARGO AREA - COMPACTOR
– Hot ashes discarded in household refuse
– Hazardous Material reactions in collected refuse

IMMEDIATE ACTION:
If vehicle catches fire during operation:
•
IN A SAFE LOCATION !
– PULL ENTIRELY OFF THE ROAD
– Into a paved parking lot, or open field
– NEVER at a gas station!
• CONTACT YOUR DISPATCHER

FIRE IN CAB:
• TURN OFF THE IGNITION!
Stops flow of current to equipment
• EXIT THE CAB!
Identify the source of smoke or fire
• EXTINGUISH THE FIRE ONLY IF:
1) You know what is burning, and fire is small / contained.
2) Extinguisher is available and you have been trained
