WHO CAN INSPECT A FIRE EXTINGUISHER

FIRE EXTINGUISHERS

• Determine fullness by weight or by “hefting.” Invert & shake it will help ensure “caking” or hardening of powder has not occurred.

• Visually examine for obvious physical damage, corrosion, leakage, or a clogged nozzle.

• Check to see if the pressure gauge is in operable range.

• Learn your building evacuation plan.

• Know where your two nearest exits are located. Learn how doors swing and where stairs lead.

• Learn the sound of your building fire alarm.

• Post emergency numbers (including security and first aid) near your telephone.

• Plan your escape.

When you notice a fire:

When you hear the fire alarm:

· Leave at once

· Do not delay yourself by gathering personal items. YOUR SAFETY ALWAYS COMES FIRST.

· Before you open any door, feel the door with the back of your hand. If the door is cold, slowly open it.

· The stairway will be your primary escape route. Never, never use

elevators under any circumstances.

· Stuff the cracks around doors with towels, rags, clothing or tape, and cover vents to keep out smoke.

· Stay low to the floor, and if possible, cover your mouth and nose with a damp cloth or dust mask to help you breathe.

If you are trapped in smoke or heat:

· Wait at a window and signal for help. Do not panic or jump!! WAIT!

· If possible, open the window at the topor bottom, but do not break it, you may need to close the window if smoke rushes in.

· Be patient. Rescuing all the occupantsof a building can take several hours.
