weight of the structure, structural members, building components, and any other features permanently attached to the building that are constant and immobile.
process of removing a hazardous foreign substance from a person, clothing, or area.
also known as decon
overall plan for incident control established by the incident commander that involves protection of exposures, as opposed to aggresive, offensive intervention.
part of the sprinkler assembly that creates the discharge pattern of the water.
fire suppression system that consist of piping and open sprinklers. a fire detection system is used to activate the water or foam control valve. when the system activates, the extinguishing agent expels from all sprinkler heads in the designated area.
deluge sprinkler system
water supply system supplied directly by a system of pumps rather than elevated storage tanks.
direct pumping system
process of being spread widely.
actions to control movement of a hazardous material to an area that will produce less harm.
process of acquiring water from a static source and transferring it into a pump that is above the sources level; atmospheric pressure on the surface forces the water into the pump where a partial vacuum was created.
fire hydrant that has its operating valve located at the base or foot of the hydrant rather than in the barrel of the hydrant. when operating properly, there is no water in the barrel of the hydrant when it is not in use. these hydrants are used in areas where freezing may occur.
fire suppression system that consist of closed sprinklers attached to a piping system that contains air under pressure. when a sprinkler activates, air is released that activates the water or foam control valve and fills the piping with extinguishing agent.
dry- pipe sprinkler system
extinguishing system that uses dry chemical as the primary esxtinguishing agent; often used to protect areas containing volitile flammable liquids.
extinguishing agent suitable for use on combustible metal fires.
extra fold placed along the length of a section of hose as it is loaded so that its coupling rest in proper position.
rope designed to stretch under load, reducing the shock of impact after a fall.
the edge of a pitched roof that overhangs an outside wall. attic vents in typical eaves provide an avenue for an exterior fire to enter the attic.
the physical process of immediately reducing contamination of individuals in potentially life threatening situations, with or without the formal establishment of a decontamination corridor.
manual that identifies hazardous materials labels/placards; also outlines initial actions to be taken at haz mat incidents. developed jointly by US, mexican, and canadian transportation agencies.
formerly known as North American Emergency Response Guidbook, NAERG
emergency response guidbook (ERG)
chemical reaction that absorbs thermal energy or heat.
harmful viruses and bacteria; when used deliberaltely, they are also known as biological weapons.
controlled process of leaving or being removed from a potenially hazardous location, typically involving relocating people from one area of danger or potential risk to a safer place.
intended and controlled exhaust locations that are created or improved at or near the fire to allow products of combustion to escape the building.
chemical reaction that releases thermal energy or heat.
contact with a hazardous material, causing biological damage; typically by swallowing, breathing, or touching. exposure may be short term (acute exposure), of intermediate duration, or long term (chronic exposure).
structure or seperate part of the fire ground to which a fire could spread.
variable-length ladder of two or more sections that can be extended to a desired height.
incident in which a trapped victim must be removed from a vehicle or other type of machinery.
