fire
what type of class of fire has combustible materials like sodium??
class D
What class of fire involves cooking oils?
class K
What class of fires includes rubber,paper and curtains?
class A
it is anything that can burn and contains the potential energy released during combustion.
fuel
It is the energy component of the combustion process and is responsible for the initial ignition.
Heat
serves as the oxidizing agent for the combustion process.
Oxygen
the fourth component needed for combustion.
The chemical Chain Reaction
what is conduction?
the transfer of heat from one body to another by direct contact of two bodies.
Convection is?
the transfer of heat energy by the movement of fluids from the source of heat to a cooler part.
radiation is?
transfer of heat by infrared light.
It involves petroleum.
class B
includes electrical fires.
class C
involves aluminum.
class D
Similar to class B fires
class K
what to do when someone catches on fire?
Stop,drop and roll
Salt in not effective for?
class B fires
what is the chemical in dry chemical fire extinguisher?
Mono Ammonium Phosphate
removes heat and displaces Oxygen.
HCFC
powder type,less toxic,non corrosive,and non conductor of electricity.
Dry chemical
chemical in AFFF
Aqueous Film Forming Foam
Water based with 3 percent or 6 percent concentration.
AFFF
Consist of water and potassium acetate, potassium carbonate,and potassium citrate.
Wet chemical Fire Extinguisher
Has low velocity applicator to ensure that the M28 or 12 powder is applied gently and efficiently.
Dry Powder Extinguisher
responsible for controlling the flow of the agent.
Valve
a plastic that is placed to keep the pull pin from falling out accidentally.
Tamper seal
allows the extinguishing agent to travel from the tank to the base of the fire.
Discharge Hose
which the extinguishing agent disperses
Discharge nozzel
Allows the owner or person responsible for the recording of the dates.
Monthly Inspection Tag
where your professional fire and security provider records the date.
Annual Inspection Tag
In S-A-F-E,what is the A for?
Alert the authorities
In S-A-F-E,What is the E for?
Evacuate
In S-A-F-E,What is the S for?
Sound the alarm
What is the golden rule you mist remember?
NEVER GO BACK IN THE BURNING BUILDING
An open flame.Can easily ignite all combustible materials nearby.
Candles
Creates fire using friction.
Matches
Ligthed charcoal is made by heating wood in the absence of?
Oxygen
uses fuel such as kerosene
Lamps
Fire can also occur in the presence of various fuel loads(select four.)
Scattered papers
Clutters at home
plastics
tall and dry grasses
Baking soda ?
gives of C02,great for soaking up the fire's heat.
why use pot lids to suppress fires?
it's a physical barrier between flames and the surrounding air.
if the pressure gauge is at the___it means that it is undercharged.
left
does not have pressure gauges
C02
First stage of fire development
Incipient stage
begins when the three elements of fore are present in a correct ratio.
ignites a fire
what supports fire to help it grow?(select multiple)
Oxygen
fuel
proximity to initial fire
What is thermal layering?
Pushes cooler air down
As heat builds up,this produces?
Turbulent smoke
Flashover is when?
sudden ignition of all combustible materials in a confined area
stage that is hardest to suppress
stage 3
a fully developed fire may exibit?(choose multiple)
darkened or black smoke
substantial radiated heat
flames visible on the exterior of the structure
small fires can quickly get out of control in as little as..

flashovers can quickly get out of control in as quickly as..
3 mins
Typically,heat generated by fire naturally rises where it is disapated into the surrounding air,but in an _______________,this heat is trapped ny the ceiling which the travels______, spreading the fire across the entire room and engulfing it in moments
enclosed space , horizontally
heat generated from ________ is more dangerous than the flame itself
structural fires
within minutes,room temperature in a fire can be ?
40⁰C
As heat naturally rises and gets trapped,upper thermal layers can reach up to
820⁰C
inhaling even small amount of smoke can?(based on the module provided)
numb your senses and leave you dazed
it is a colorless,tasteless,and odorless gas that is extremely difficult to detect as it is more dangerous when a fire has this element's presence.
Carbon Monoxide
it is produced when fuels such as oil,coal,gas,and wood are burned and is often known as the..
Silent killer
spell the chemical in Dry Chemical
Mono Ammonium Phosphate
