Training Blueprint — Fire Safety
Preventing vehicle fires
Second to maintaining your fleet, the best way to prevent loss and injury due to fires is to make sure your drivers know the common causes of vehicle fires and how to protect their cargo, vehicle, and themselves if a fire starts when they are on the road.
TIP: Before reviewing common causes of vehicle fires with your drivers, ask them to list as many as they can think of, then fill in gaps from the list and your personal experience.
Vehicle fire causes
Vehicle fires are usually caused by mechanical problems, commonly including:
- Damage or excessive wear in the exhaust system. Exhaust gas temperatures can reach 1,000 to 1,200 degrees. If heat from the exhaust pipe or hot exhaust gas contacts a flammable material (carpeting, rubber mats, etc.), the material can easily catch fire.
- Short circuits in a location not protected by a circuit breaker or fuse. For example, if battery cables rub against the metal of the vehicle and wear through, there is no breaker or fuse to stop the electrical current. The large amount of heat created could ignite any combustibles in the area.
- Tires with low air pressure. The friction of a low tire or tires in contact with each other or a vehicle part can create enough heat to start a tire on fire.
- Fluid leakage. Any time a vehicle is leaking fuel, grease, or oil, it is one heat source away from a fire.
- Excessive hub heat generated by bad bearings, a leaky hub seal, or a dragging brake. The bus fire in Texas that killed 23 people on board during the Hurricane Rita evacuation started when wheel bearings overheated and started a tire on fire.
One study showed that tires were the item first ignited in 30 percent of large truck fires and 12 percent of bus fires.
TIP: Careless use of smoking materials can easily start a vehicle fire. Make sure your drivers know if your carrier has a smoking ban. If your company doesn’t already have a ban in place, consider working with management to implement one.
As you can see, drivers can avoid most of these hazards by performing thorough pretrip and post-trip inspections. However, if prevention does fail, it is important that drivers understand how to use fire extinguishers.
Extinguisher use
TIP: Ask your trainees to discuss where they think the best place to store a fire extinguisher is. Consider posing different scenarios (fire on the passenger side of the cab, tire fire, engine fire, etc.) so drivers can think through whether they’d be able to access the extinguisher safely and easily in each case.
To correctly use the extinguisher, the driver simply needs to remember the acronym PASS:
- PULL the safety pin out.
- AIM the extinguisher nozzle at the base of the flames (what is burning) rather than at the actual flames.
- SQUEEZE the handles together to activate the extinguisher.
- SWEEP the extinguishing agent across the area that is burning.
TIP: During fire safety training, give all your drivers the opportunity to use a fire extinguisher. Watching a video of someone else putting out a fire isn’t the same as doing it yourself.
