physical barriers
dead zones
interference
ambient noise
what should you do when receiving and talking into a radio
give a couple seconds before speaking into it and acknowledge the message
if you are having troubles using the radio while wearing scba? should you take off face piece and try again? if not what do you do.
place the radio against your throat
What is type 1 construction. explain it
Fire resistive. highest level of protection.reinforced concrete. new buildings
Type 2 construction
non combustible. not as good as type 1.
concrete
type 3 construction
ordinary construction. buisness and residential. truss systems
type 4 construction

every single house nowadays
what’s a factory built home
made in a factory shipped to the location
include mobile homes
what are some parts of a top level in a building
joists, rafters, trusses
what’s a masonry wall
fire walls made of concrete that divide a building/stop a fire spread
what’s a pressurized stairwell and how does it work
found in hotels. doors are always closed. air blows to help during a fire and escape.
what’s a jealousie window and whats it look like? why is it difficult for firefighters to force entry
many windows going horizontal. reinforced with metal make it impossible to get into
what is a endothermic reaction vs an exothermic reaction. give an example.
exothermic reaction releases energy while endothermic absorb energy.
exothermic=fire
endothermic=converting water to steam
what are the 3 parts of the fire triangle. explain how it works
oxygen,heat, fuel.
a fire can’t survive without 1. it needs all 3 and firefighters need to understand how to eliminate one if they want to fight a fire
whats pyrolysis
when a solid fuel is converted into a gaseous fuel
what is a piloted ignition
most common type of fire is started. when a fuel and oxygen source encounter a heat source
auto ignition
natural start to a fire. sometimes forest fires
what is a sign of incomplete combustion
smoke
what is asphyxiation
a fatal level of oxygen deficiency in the blood
explain conduction,convection, radiation
conduction is direct heat
convection is like an oven, heat transferred tuesday
radiation microwave that sends waves of heat
what is vapor density
the density of gases in relation to air. of it will float or sink below air. air is 1
what is flash point?
the minimum temperature at which a liquid gives off sufficient vapor’s to ignite but not sustain combustion
what is fire point
the point where the fire has all it needs to sustain combustion
what is solubility
the extent of which a substance will mix with water
what is miscible
matériels in water that will mix in any proportion
what’s a polar solvent
flammable liquids containing alcohols
what percent does air consist of
21
what is LEL
lower explosive limit
minimum concentration of fuel vapor and air that support combustion
meaning it’s too lean to burn
what is UEL
upper explosive limit
is the concentration cannot take place
too rich to burn
what is chemical flame inhibition
when an extinguishing agent disrupts the process of combustion
example: fire extinguisher
what is a fuel limited fire vs a ventilation limited fire
when sufficient oxygen is available for flaming combustion. =fuel limited
fuel limited dont have enough oxygen
=oxygen limited
what are the 4 stages of fire development
1.incipient stage
2.growth stage
3.fully developed stage
4.decay stage
what is a rollover
a rollover is a strong indicator a flash over is about to happen. looks like a bunch of particulate filled smoke begins to rollover near the ceiling looking for a source to ignite. flames begin to form at the top of the ceiling
flashover
worst thing to ever happen. everything in the room becomes on fire and all hell brakes loose. happens when an oxygen is introduced into a room full of fuel
backdraft
makes a sucking of air to try and stay alive looking for an oxygen source
