2.20 – Accident Procedures

When you’re in an accident and not seriously hurt, you need to act to prevent further damage or injury. The basic steps to be taken at any accident are to:

  • Protect the area.
  • Notify authorities.
  • Care for the injured.

2.20.1 – Protect the Area

The first thing to do at an accident scene is to keep another accident from happening in the same spot. To protect the accident area:

  • If your vehicle is involved in the accident, try to get it to the side of the road. This will help prevent another accident and allow traffic to move.
  • If you’re stopping to help, park away from the accident. The area immediately around the accident will be needed for emergency vehicles.
  • Put on your flashers.
  • Set out reflective triangles to warn other traffic. Make sure other drivers can see them in time to avoid the accident.

2.20.2 – Notify Authorities

If you have a cell phone or CB, call for assistance before you get out of your vehicle. If not, wait until after the accident scene has been properly protected, then phone or send someone to phone the police. Try to determine where you are so you can give the exact location.

2.20.3 – Care for the Injured

If a qualified person is at the accident and helping the injured, stay out of the way unless asked to assist. Otherwise, do the best you can to help any injured parties. Here are some simple steps to follow in giving assistance:

  • Don’t move a severely injured person unless the danger of fire or passing traffic makes it necessary.
  • Stop heavy bleeding by applying direct pressure to the wound.
  • Keep the injured person warm.

2.21 – Fires

Truck fires can cause damage and injury. Learn the causes of fires and how to prevent them. Know what to do to extinguish fires.

2.21.1 – Causes of Fire

The following are some causes of vehicle fires:

  • After Accidents. Spilled fuel, improper use of flares.
  • Tires. Under-inflated tires and duals that touch.
  • Electrical System. Short circuits due to damaged insulation, loose connections.
  • Fuel. Driver smoking, improper fueling, loose fuel connections.
  • Cargo. Flammable cargo, improperly sealed or loaded cargo, poor ventilation.

2.21.2 – Fire Prevention

Pay attention to the following:

  • Pre-trip Inspection. Make a complete inspection of the electrical, fuel, and exhaust systems, tires, and cargo. Be sure to check that the fire extinguisher is charged.
  • En Route Inspection. Check the tires, wheels, and truck body for signs of heat whenever you stop during a trip.
  • Follow Safe Procedures. Follow correct safety procedures for fueling the vehicle, using brakes, handling flares, and other activities that can cause a fire.
  • Monitoring. Check the instruments and gauges often for signs of overheating and use the mirrors to look for signs of smoke from tires or the vehicle.
  • Caution. Use normal caution in handling anything flammable.

2.21.3 – Fire Fighting

Knowing how to fight fires is important. Drivers who didn’t know what to do have made fires worse. Know how the fire extinguisher works. Study the instructions printed on the extinguisher before you need it. Here are some procedures to follow in case of fire.

Pull Off the Road. The first step is to get the vehicle off the road and stop. In doing so:

  • Park in an open area, away from buildings, trees, brush, other vehicles, or anything that might catch fire.
  • Don’t pull into a service station!
  • Notify emergency services of your problem and your location.

Keep the Fire from Spreading. Before trying to put out the fire, make sure that it doesn’t spread any further.

  • With an engine fire, turn off the engine as soon as you can. Don’t open the hood if you can avoid it. Shoot foam through louvers, radiator, or from the vehicle’s underside.
  • For a cargo fire in a van or box trailer, keep the doors shut, especially if your cargo contains hazardous materials. Opening the van doors will supply the fire with oxygen and can cause it to burn very fast.

Extinguish the Fire. Here are some rules to follow in putting out a fire:

  • When using the extinguisher, stay as far away from the fire as possible.
  • Aim at the source or base of the fire, not up in the flames.

Use the Right Fire Extinguisher

  • Figures 2.20 and 2.21 detail the type of fire extinguisher to use by class of fire.
  • The B:C type fire extinguisher is designed to work on electrical fires and burning liquids.
  • The A:B:C type is designed to work on burning wood, paper, and cloth as well.
  • Water can be used on wood, paper, or cloth, but don’t use water on an electrical fire (can cause shock) or a gasoline fire (it will spread the flames).
  • A burning tire must be cooled. Lots of water may be required.
  • If you’re not sure what to use, especially on a hazardous materials fire, wait for firefighters.
  • Position yourself upwind. Let the wind carry the extinguisher to the fire.
  • Continue until whatever was burning has been cooled. Absence of smoke or flame does not mean the fire cannot restart.

Test Your Knowledge

  • What are some things to do at an accident scene to prevent another accident?
  • Name two causes of tire fires.
  • What kinds of fires is a B:C extinguisher not good for?
  • When using your extinguisher, should you get as close as possible to the fire?
  • Name some causes of vehicle fires.

These questions may be on the test. If you can’t answer them all, re-read subsections 2.20 and 2.21
