Transfer of heat through direct contact.
The question is: What is conduction?
Belt with a hook that secures the firefighter to the ladder,
What is a ladder belt?
Oxygen, fuel, heat, and a self-sustained chemical reaction.
What are the components of the fire tetrahedron?
The systematic removal of heated air, smoke, and fire gases from a burning building and replacing them with cooler air.
What is a ventilation?
Fire engines, fire hydrants, tanker trucks, brush trucks, lakes and rivers.
Where do firefighters get water?
An automatic valve that permits liquid flow in only one direction.
What is a check valve?
Single ladders equipped with folding hooks on one end.
What is a roof ladder?
Stage of a fire with high heat, heavy smoke and little or no flames.
What is smoldering?
The tendency of gases to form into layers according to temperature, with the hottest at the top going down to the coolest at the bottom.
What is the thermal layering?
Pressure in a water distribution system when no hydrants or water is flowing.
What is static pressure?
Heat transfer by circulation.
What is convection?
A ladders main structural member supporting rungs or rung blocks.
What are beams?
The rapid oxidation of a material in the chemical process of combustion, releasing heat, light, and various reaction products.
What is fire?
Created when a ventilation opening is made in the upper portion of a building and air currents throughout the building are drawn in the direction of the opening.
What is the chimney effect?
What are steps in testing the operability of a fire hydrant?
Transfer of head through direct contact.
What is conduction?
A rope or cable used for hoisting, or lowering, a ladder with multiple sections.
What is a halyard?
The lowest temperature at which a materials vapors ignite if given an ignition source.
What is flash point?
This should only occur when hoseline crews are ready to move in and attack the fire.
When should ventilation occur?
Wet-barrel, dry-barrel, high-pressure and wall.
What are types of hydrants?
The rapid chemical process of oxidation of a substance with oxygen that occurs fast enough to produce both heat and light in the form of either a glow or flame.
What is combustion?
Item affixed to the ladder indicating when a ladder needs to be taken out of service for testing due to exposure to excessive heat.
What is a heat-sensor label?
The primary composition is water vapor that is combined with other pollutants like carbon monoxide, carbon dioxide, nitrogen oxide, irritant volatile organic compounds, other toxins and very small particulate matter.
What is smoke?
a. Confinement and excessive heat
b. Smoke stained windows
c. Smoke puffing at intervals from the building
d. Pressurized smoke coming from small cracks
e. Little visible flame from the exterior of the building
f. Black smoke becoming dense gray-yellow
When is a backdraft possible?
Compares the amount of heat generated by a fire to the amount of water required for cooling fuels to below their ignition temperature.
What is fire flow requirement?
