Fire Safety
Class C
A blue circle indicates these electrical fires. Carbon dioxide and dry chemical extinguishers are appropriate for this type of fire.
A.
Aim at the base of the fire
Fire Triangle
Heat, Fuel, and Oxygen
P.
Pull the pin
S<
Squeeze the handle to admit the exhausting agent
S>
Sweep at the base of the fire
Deprived of oxygen when
an exhausting agent smothers the fire with gas, foam, or powder
a fire is called when
an extinguishing agent covers the fire source
PM 5
become familiar with REG's emergency action plan for fire (know where the Emergency Procedures Booklet is)
PM 4
call professional help immediately, don't let a fire get out of control
Class B
class type is denoted by a red square. Flammable liquids, gases, and grease make up this class. They are harder to fight and require a special kind of extinguisher. Use foam, carbon dioxide, and dry chemical extinguishers on this type of fire. Also, water fog and vaporizing liquid extinguishers can be used.
Class D
fires are caused by combustible metals including magnesium, titanium, zirconium, and sodium. They are represented by a yellow star symbol. These fires require specialized techniques to extinguish them. None of the common extinguishers should be used since they can actually increase the intensity of the fire by adding additional chemical reactions.
Class K
fires are caused by vegetable oils and non-vegetable cooking fats used in commercial and noncommercial cooking equipment. The secondary fire extinguisher utilizes a specialized low ph foam this sprayed in a fine mist that smothers the flame as well as cooling the fuel source
Class K Fire Extinguisher
is designed to be effective on Class K fires by expelling a wet foam containing potassium acetate for 40 seconds; the agent is used to prevent grease and oil fires by spraying a fine mist to cool the fuel source; must be 10 to 12 feet away
All Purpose Fire Extinguisher
is designed to be effective on Classes A, B, and C; expels agent in about 8 to 10 seconds; must be at least 8 to 10 feet from the fuel source
fuel is eliminated when
it is wetted by foam
PM 1
keep your work areas free of clutter
PM 2
know what chemicals you work with and how to handle and store them properly (acquaint yourself with the MSDS binder)
PM 3
know what you are expected to do in case of a fire emergency
Class A
the most common fire, involves ordinary materials such as wood, paper, rubber, and plastics. A green triangle represents this class type. The common extinguishing agent is water, but dry chemicals are also effective.
Electrical fires
the most common type of industrial fire
Extinguishers work because
they contain an agent which eliminates one of the vital elements of the fire.
