Fire hazards
Can help you take all of the science knowledge you’ve just gained, and use it to prevent fires and keep people safe
THE FIRE TRIANGLE
THREE PARTS OF THE FIRE TRIANGLE:
-Oxygen
-Heat
-Fuel
Causes of fire:
a.) Faulty electrical wiring or connection
b.) LPG- related
c.) Neglected cooking or stove
d.)cigarette butt
e.) Unattended open flame: torch or sulo
CLASSIFICATION OF FIRE
Class A
Class B
Class C
Class D
Class K
Fuels are ordinary combustibles such as wood, paper, plastic, or anything that leaves ash.
CLASS A fire
Fuels are FLAMMABLE or COMBUSTBLE LIQUIDS like petroleum oil, gasoline, paint, and flammable gasses such as propane and butane.
Cooking oils and grease are NOT part of Class B fires
CLASS B fire
Fuels are ENERGIZED ELECTRICAL FIRES like motors, transformers, and appliances.
Once the power or source of electricity is removed, the fire becomes one of the other classes of fire
CLASS C fire
Fuels are COMBUSTIBLE METALS like potassium, sodium, aluminum, titanium, and magnesium
CLASS D fire
Fuels are COOKING OILS, grease such as animal fat and vegetable fts.
CLASS K fire
Is all around you. It is an important part of atmosphere
OXYGEN
Can come from things like fireplaces, lamps, and ovens
HEAT
Is something that can catch on fire, meaning it is FLAMMABLE
FUEL
Precautionary measures
For heat
For fuel
For oxygen
precautionary measures FOR HEAT
Make sure that materials that could easily warm up are not near sources of heat.
precautionary measures FOR FUEL
recount the different types of fuel discussed in the classes of fire. Make sure that these materials are organized and do not have any contact with other combustible materials.
