This document discusses fire hazards and safety. It defines a fire hazard as anything that increases the likelihood of a fire starting or spreading. It then covers the chemistry and stages of fire, classes of fire based on the materials involved, common fire causes such as appliances and cooking, and procedures for responding to a fire, including using a fire extinguisher and evacuation plans.
2. FIRE HAZARD
Anything which increases the likelihood
of fire.
Includes situations that increase the
likelihood of fire or may impede escape
in the event fire occurs.
16. 3 STAGES OF FIRE
Incipient Stage
A region where preheating, distillation, and slow pyrolysis are in
progress.
Smoldering Stage
Region of fully developed pyrolysis that begins with ignition and
includes the initial stage of combustion.
Flaming Stage
A region of rapid reaction that covers the period of initial
occurrence of flame to a fully developed fire.
17. CLASSES OF FIRE
Class A – fires involving organic solids like paper
and wood
Class B – fires involving flammable liquids
Class C – fires involving flammable gases
Class D – fires involving metals
Class E – fires involving cooking oils
18. FIRE HAZARDS
Live flames

21. CAUSES OF FIRE
Accidents and carelessness
Many people believe that f they are careful
they are much less likely to have fire
Being careful will not stop fire from happening
Most fires are not caused by carelessness
They are caused by everyday living that is
almost impossible for us to change
22. CAUSES OF FIRE
Electrical Wiring, Outlets, and Faulty
Wiring
Older homes are particularly susceptible as
they were not wired for the many appliances
that we have filled our homes with.
Homes built in the 50’s-70’s have aluminum
wiring that gets very hot and increases the
chance of fire.
23. CAUSES OF FIRE
Appliances
Lamps, toasters, refrigerators, clothing iron, and
even baby monitors can short out.
Appliances can be unplugged when not in use.
Cooking
Major cause of residential fires.
Not due to effective stoves but unattended pots or
burner.
24. CAUSES OF FIRE
Children playing
Burns = no.1 cause of accidental deaths in
children under 2 years old.
Fire and burn injuries are the 2nd leading cause
of accidental deaths in children ages 1-4 and
3rd leading cause of injury and death for ages
1-8
25. WHAT DOYOU DO WHEN…
1.You are in a building and the machine near you combusts?
2.The fire alarm sounds in your building?
3.The room or hallway is caught in smoke?
4.You trapped in a room and there is fire outside? (what do you
do to keep out the smoke?)
5.Your clothing is on fire?
6. A fire is starting and there is a fire extinguisher near you?
7.Your classmate is on fire?

Confine the fire by closing all windows and
doors.
Evacuate and leave the building
Extinguish the fire if it can be done safely
28. 2. HOWTO SURVIVE A
BUILDING FIRE
