Fire load (Btu/sq ft)
An estimate of the amount of heat that will be given off during ordinary combustion of all the fuel in a given space; e.g., a bedroom or a lumberyard.
Fire Lookout
A person that keeps an eye for possible fire starts and conditions. They can work in a Fire Lookout Tower or perform the duty as a role for a fire crew on the fireline.
Fire lookout tower
A structure located at a high vantage point to house and protect the person performing the duties of a Fire Lookout.
Fire marshal
Administrative and investigative office for fire prevention and arson investigation.
Fire point
Temperature at which materials give off flammable gases that will sustain fire, typically higher than flash point. Temperature at flashover.
Fire prevention
Fire safety; standards for minimizing fire hazards.
Fire retardant
Any substance (except plain water) that by chemical or physical actions reduces flammability of fuels or slows their rate of combustion. See retardent slurry, AFFF, and Foam as examples.
Fire shelter
An aluminized tent offering protection by means of reflecting radiant heat and providing a volume of breathable air in a fire entrapment situation. Carried as a safety tool, fire shelters should only be used in life threatening situations, as a last resort, as severe burns or asphyxiation often result.
Fire shirt
Distinctive yellow shirts made of Nomex or other lightweight materials of low combustibility, used as uniform PPE of wildland firefighters.
Fire station alert system
Fire department dispatching system using radio controls to activate remote signals at designated fire stations and to transmit emergency information via audio or digital channels.
Fire streams
Water (possibly mixed with foam) emitted at nozzle and directed at burning materials.
Fire tetrahedron
The fire tetrahedron is based on the components of igniting or extinguishing a fire. Each component represents a property necessary to sustain fire: fuel, oxygen, heat, and chemical chain reaction. Extinguishment is based upon removing or hindering any one of these properties.
Fire triangle
Model for understanding the major components necessary for fire: heat, fuel and oxygen.
Fire wall
Building structure designed to delay horizontal spread of a fire from one area of a building to another; often regulated by fire code and required to have self-closing doors, and fireproof construction.
Fire watch
Fixed or mobile patrols that watch for signs of fire or fire hazards so that any necessary alarm can be quickly raised or preventive steps taken.
Fire weather
Weather conditions that affect fire vulnerability, fire behavior and suppression.
Fire-resistant
Materials designed or treated to have an increased fire point.
Firebreak
A natural or constructed barrier used to stop or check fires that may occur, or to provide a control line from which to work.
Firefighter
People who respond to fire alarms and other emergencies for fire suppression, rescue, and related duties.
