Familiarize yourself with the fire extinguisher locations that are in your immediate work area or truck. These locations are generally marked in red or identified with a sign.
The general guidelines for using any fire extinguisher are:
· Follow the instructions on the extinguisher.
· Spray the stream at the base of the flames.
· Use a side-to-side sweeping motion.
· Keep your back to the wind.
· Use short bursts from the fire extinguisher.
· Don’t waste the dry chemicals or other extinguishing agents. Remember that portable fire extinguishers have only a small supply of extinguishing agent and their rate of discharge and range is limited.
· If dealing with a flammable liquid in a closed container, aim the stream at the container to cool it and prevent an explosion.
· Be certain the fire is actually out before leaving.
Every employee should know the classes of fires and which type of extinguishers to use for a particular situation. The letters (A, B, C, or D) show the class of fire that the extinguisher should be used to put out:
· Ordinary Combustibles Class A (Green Triangle)
· Flammable Liquids Class B (Red Square)
· Electrical Equipment Class C (Blue Circle)
· Combustible Metals Class D (Yellow Star)
Stick-on-labels are placed on most portable fire extinguishers and show what class or type of fire that the extinguisher would be used to put out. At most locations, we uses a multi-purpose extinguisher, which can be used on many different fires. Always read the label before using a fire extinguisher.
