Fire: Prevention and Response Flashcards
the first stage where fuel and oxygen are exposed to heat, resulting in a sustained chemical reaction.
IGNITION STAGE
the initial flame become another source of heat and additional fuel ignites
GROWTH
with presence of more heat coming from the fire itself, the fire spreads and consumes all available fuel.
FULLY DEVELOPED
when the fire consumes all available fuel, the
temperature decreases.
DECAY (BURNOUT)
IDENTIFY WHAT TYPE OF EXTINGUISHER IS USED AND ITS COLOR
used on paper, wood, coal, cardboard, and other solid fuel fires
WATER (solid red)
IDENTIFY WHAT TYPE OF EXTINGUISHER IS USED AND ITS COLOR
used on solid fuel fires as well as flammable liquids
FOAM (cream)
IDENTIFY WHAT TYPE OF EXTINGUISHER IS USED AND ITS COLOR
used on any kind of fire except of Class F cooking oils
POWDER (blue)
IDENTIFY WHAT TYPE OF EXTINGUISHER IS USED AND ITS COLOR

the triangle shows the three components
necessary to have fire: fuel, heat, and oxygen.
IMPORTANT
TRIANGLE OF COMBUSTION
it is now used to describe the elements of fire.
FIRE TETRAHEDRON
is the rapid oxidation of a material in the exothermic chemical process of burning, releasing heat, light and various reaction products.
IMPORTANT
Fire
it occurs when the heat passes through direct contact with a solid material.
CONDUCTION
it is the flow of fluid or gas from hot areas to cooler areas.
CONVECTION
heat travels through electromagnetic waves.
RADIATION
is an active fire protection device used to extinguish or
control small fires, often in emergency situations. It is not intended for use on an out-of-control fire.
fire extinguisher
Usually kept in kitchen and wall mounted
• Single use fiberglass construction
• Designed to suppress/smoother fire
• Mainly used for fat/cooking oil fires
• DISPOSE after use
• NEVER wash or reuse
• REQUEST a replacement after use
