FAST (or F.A.S.T.):
Firefighter assist and search team (also called
rapid entry team or
rapid intervention team/crew)—firefighters assigned to stand by for rescue of other firefighters inside a structure; an implementation to support the
two-in, two-out rule; may have specialized training, experience and tools. While all of these versions of the name for a firefighter rescue crew either have been used or continue to be used in several areas, the National Incident Management System (
NIMS) has determined that rapid intervention crew ("RIC") will be the national term. Current U.S. federally mandated training programs are in the process of standardizing this and other terms under DHS and FEMA. F.A.S.T operations became officially mandated after the Worcester, MA Cold Storage fire, which claimed the lives of 6 firefighters, after they became disoriented in the smoke and subsequently ran out of air. •
FDC (Fire department connection): Location in which pumping apparatus hooks to a buildings standpipe and or sprinkler system. Usually a 3″ female connection. •
Fire barn: Another term for
fire station. Originally it referred to a stable which housed horses and the fire apparatus which they hauled. Although it may be colloquially employed to describe any such structure, the term is now most commonly used in rural areas. •
Firebreak: Especially in hilly or mountainous areas, roads or paths cut through brush with a
tractor,
bulldozer or other construction equipment. The purpose of these is to have an area with no brush, and thus, no fuel, so that a fire will hopefully burn out rather than jumping to another area with brush. Also to ensure vehicular access to brush areas. •
Fire buff Someone with considerable interest (a fan) in fire fighting and emergency services, while not being an active member of these services. •
Fire code (
Fire safety code): regulations for fire prevention and safety involving flammables, explosives and other dangerous operations and occupancies. •
Fire complex: (U.S.
complex fire) Area of fires - many of the areas have multiple fires with multiple fronts. •
Fire engineering: Scientific design of materials, structures and processes for fire safety •
Fire escape: A building structure arranged outside to assist in safe evacuation of occupants during an emergency; may connect horizontally beyond a
fire wall or vertically to a roof or (preferably) to the ground, perhaps with a counter-weighted span to deny access to intruders. •
Fire Fighter Fatality Investigation and Prevention Program (FFFIPP)—Program administered by the
National Institute for Occupational Safety and Health (NIOSH), a department of the
Centers for Disease Control (CDC). It performs independent investigations of firefighter fatalities in the United States, also referred to as line of duty deaths (LODD). The programs goals are: 1.) to better define the characteristics of line of duty deaths among firefighters, 2.) to develop recommendations for the prevention of deaths and injuries, and 3.) to disseminate prevention strategies to the fire service. •
Firefighter: People who respond to fire alarms and other emergencies for fire suppression, rescue, and related duties. •
Firefighter assist and search team: See
FAST. •
Fire flow: The amount of water being pumped onto a fire, or required to extinguish a hypothetical fire. A critical calculation in light of the axiom that an ordinary fire will not be extinguished unless there is sufficient water to remove the heat of the fire. •
Fire gas ignition: ‘an ignition of accumulated fire gases and combustion products, existing in, or transported into, a flammable state. There are a wide range of events that can be conveniently grouped under the heading Fire Gas Ignitions (FGI's) and such phenomena can generally be defined as -. Any such ignition is usually caused by the introduction of an ignition source into a pre-mixed state of flammable gases; or the transport of such gases towards a source of ignition; or the transport of a fuel-rich mixture of gases into an area containing oxygen and an ignition source. The ignition is not reliant on the action of airflow/oxygen in the direction of an ignition source, which is clearly recognised as a backdraft event. •
Fireground: The operational area at the scene of a fire; area in which
incident commander is in control. Also used as name of radio frequency to be used by units operating in the fireground, as in “Responding units switch to
fireground.” •
Fire hall Another term for
fire station. •
Fire hazard: Materials, structures or processes that may result in creating a fire, permitting a fire to grow undetected, or preventing people from escaping a fire. •
Firehouse: Another term for
fire station. •
Fire hydraulics: The study of pumps, hoses, pipes, accessories and tools for moving water or other extinguishing agents from a water supply to a fire. •
Fire inspector: A person responsible for issuing permits and enforcing the
fire code, including any necessary premises inspection, as before allowing (or during) a large indoor gathering. •
Fire line: A boundary of a fire scene established for public safety and to identify the area in which firefighters may be working. •
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. More casually, the amount and type of contents in a given space. •
Fire marshal: Administrative and investigative office for fire prevention and arson investigation. •
Fire officer: A person tasked with organizing and directing firefighters. See also
company officer and
chief officer. •
Fire point: temperature at which materials give off flammable gases that will sustain fire, typically higher than
flash point. Temperature at
flashover. •
Fire police:
Special constables attached to a fire department, tasked with ensuring the safety and security of emergency scenes as well as general assistance to the fire department and other agencies. •
Fire prevention: Fire safety; standards for minimizing fire hazards. In some departments also the name of the division tasked with promoting fire safety and fire code compliance in the community. •
Fire prevention week: An annual observation of
fire safety education in the
United States and
Canada, often involving lectures or demonstrations by
firefighters, sponsored by the
National Fire Protection Association, since 1925. •
Fire-resistant: Materials designed or treated to have an increased fire point. •
Fire station: A structure which, in addition to housing apparatus and equipment, often includes living quarters and training facilities for the use of firefighting personnel when on-duty. •
Firestorm: A conflagration of great enough proportions to noticeably create its own wind conditions. •
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: An outdated model for understanding the major components necessary for fire: heat, fuel and oxygen. See also
fire tetrahedron for the currently used model in firefighting. •
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 warden: Appointed post for issuing rural fire permits in a given jurisdiction and maintaining equipment and manpower readiness for responding to
wildland fires. •
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. Commonly established at commercial, industrial and multi-occupancy structures, usually by building and property Maintenance or Security personnel if the on site fire alarm and/or sprinkler/suppression system is out of service for repairs, or a Fire crew assigned to the scene after a large fire to stand watch for an extended period of time in the event of a rekindle. Also called "reflash watch." •
