This document defines fire hazards and the fire triangle, which illustrates that a fire requires heat, fuel, and oxygen. It describes different classes of fires based on the type of fuel (A, B, C, D, K) and sources of fire hazards like electrical systems, lightning, flammable gases/liquids, and hot surfaces. The types of fire extinguishers and fire detection devices like smoke, heat, and flame detectors are also outlined. Guidelines are provided on when not to fight a fire and when to call for help versus attempting to extinguish small fires if it can be done safely. Proper fire safety practices involving equipment maintenance and evacuation plans in case of emergency are recommended.

1. FIRE
HAZARDS

2. What is a fire hazard?
•Conditions that favor fire development or growth
•Oxygen, fuel, and heat
•Fire hazards usually involve the mishandling of fuel
or heat
•Fire or combustion is a chemical reaction between
oxygen and a combustible fuel
•Source of ignition= Spark, flame and high
temperature are needed

3. Fire Triangle
• The triangle illustrates the
three elements a fire
needs to ignite: heat, fuel,
and an oxygen
• The fire extinguished by
removing any one of the
elements in the fire
triangle

24. Fire Detection Devices
Smoke detectors
•require a flow of air in order to work well
Heat detectors
•detect fires where there is no smoke
activated by the significant increase of
temperature associated with fire
Flame detectors
• react to the movement of flames.

26. DON’TS
•The smoke is extremely thick.
•The fire is too hot for you to get close enough to
fight it effectively.
•The fire is greater than 3 feet across.
•There are potentially hazardous substances near
the fire.
•You do not have the correct type of fire
extinguisher for the fire at hand.
•You do not know how to use the fire extinguisher.

27. DO’s
• Call the fire department.
• Begin evacuating others.
• Turn off the gas valve to prevent escalation
• Meet at the preassigned meeting place.
• Make sure that all persons have safely escaped.
• When the fire department arrives, inform a
firefighter if anyone is missing; do not reenter
the building yourself.

28. DO’s
• Regularly check electrical equipment
•Maintain proper fire safety
equipment
•Follow correct steps to put out fires
and evacuate the building

29. ACTIVITY
•Search for fire and emergency
plan symbols
•Draw a floor plan/blue print of
your home
•Make a fire escape plan for your home
with the help of the fire and
emergency plan symbols
