Basic Firefighting with 100% correct
questions and answers
#1 Cause of fire on ships... and others - correctanswer <<<<<<<<<<<CARELESS SMOKING HABITS!!!
• -DISPOSAL
• -SMOKING IN BED
• -DISREGARD FOR RESTRICTED
• AREAS
POOR HOUSEKEEPING
• -Dirty/oily machinery
• -Clothes drier lint accumulation
• -Improper , non- secured storage
THE ELEMENTS OF FIRE (fire tetrahedron) - correctanswer <<<<<<<<<<<Heat, oxygen, fuel and chemical
chain reaction
Heat - correctanswer <<<<<<<<<<<Anything that produces the required temperature for ignition will
satisfy this leg of the triangle
• -Sun
• -Open Flame
• -Chemical Reaction
• -Sparks
• -Friction
• -Static Electricity
Oxygen - correctanswer <<<<<<<<<<<The Earth's atmosphere consists of 21% oxygen. Because fire
needs oxygen to burn, the amount of oxygen available to it controls the rate at which it burns.
• Fuel - correctanswer <<<<<<<<<<<-Only vapors burn
, • -Liquids & solids must first be vaporized
Tendency of a substance to vaporize is an indication of _________________________ - correctanswer
<<<<<<<<<<<its ability to burn.
_____________ vaporize more readily than _____________ - correctanswer <<<<<<<<<<<Liquids
solids
( Gasoline has a flash point of -45 f )
Gases are already in a _________ state - correctanswer <<<<<<<<<<<vapor
Chain Reaction - correctanswer <<<<<<<<<<<You can have Oxygen - Heat - Fuel in the same place at the
same time and still not have a fire
Heat must be sufficient to bring fuel to its Ignition Temperature
FUEL - OXYGEN relationship must be balanced, i.e., be in the _________________________ -
correctanswer <<<<<<<<<<<Flammable Range
Five classes of fire: - correctanswer <<<<<<<<<<<1. Class A - combustible solids
• 2. Class B - combustible and flammable liquids and gases
• 3. Class C - energized electrical equipment
• 4. Class D - combustible metals
• 5. Class K - cooking media
Class A Fuels - correctanswer <<<<<<<<<<<-wood
• -paper
• -rubber
• -plastic
, Class B Fuels - correctanswer <<<<<<<<<<<-Liquids
• -Greases
• -Gases
Class C Fuels - correctanswer <<<<<<<<<<<-Live electrical equipment
Class d Fuels - correctanswer <<<<<<<<<<<-aluminum
-magnesium
o titanium
o zirconium
• -sodium
o potassium
o lithium
o calcium
o zinc
Class K Fuels - correctanswer <<<<<<<<<<<- cooking oils and greases (animal and vegetable fats)
To Stop a Fire - correctanswer <<<<<<<<<<<remove the fuel, or
remove the heat, or
remove the oxygen, or
interrupt chemical reaction, OR
do any combination of above
FLASH POINT (of a Liquid) - correctanswer <<<<<<<<<<<The lowest temperature at which a liquid gives
off sufficient gas to form a flammable gas mixture near the surface of the liquid
Fire flashes across the surface given sufficient oxygen and an external source of ignition
Lowest temperature at which we can have a fire
