Ch 5 Flashcards
Construction that has load-bearing exterior walls made of brick, adobe, concrete, gypsum, stone, tile, or similar materials; that has floors and roofs of combustible materials; and that has a fire-resistance rating of at least one hour
Joisted masonry construction
Construction that has load-bearing components made of wood or other combustible materials
Frame construction
A subclassification of joisted masonry construction that uses heavy timber it columns, beams, supports and ties; has a minimum two hour fire-resistance rating on bearing walls; and had an absence of floor joists.
Mill construction.
A class of construction in which the exterior walls, floor and roof of a building are constructed of, and supported by, metal, gypsum, or other non combustible materials. Not fire resistive because steel supports can twist and bend under heat.
Non combustible construction.
Masonry construction or construction that includes exterior walls of fire resistive construction with a fire-resistance rating of not less than one hour
Masonry noncombustible construction
Construction that has load-bearing walls and columns of masonry or reinforced concrete construction and that has a fire-resistance rating of one to two hours. A step down from plain fire resistive.
Modified fire-resistive construction
Construction that incorporates loadbearing members and that has a fire-resistance rating of at least two hours
Fire-resistive construction
The expected maximum amount of combustible material in a given area of a building, including both structural elements and contents
Fuel load, aka fire load
A section of a structure so well protected that fire cannot spread from that section to another, or vice versa
Fire division
A floor-to-roof wall made of non combustible materials an having no open doors, windows, or other spaces through which fire can pass.
Fire walk
Parapet
A vertical extension of a fire wall that extends above a roofline
Local ordinances or state statutes that regulate the construction of buildings within a municipality, county or state
Building codes
An extension of a fire wall through an outer wall
Fender Wall
The type or character of use of the property in question
Occupancy
Hazards that are typical for the class of loss exposures
Special hazards of the class
Hazards that are created by the activities of a particular business and that are not typical of other businesses with which it would be classed
Special hazards of the risk
Measures taken to prevent or reduce the damage done by fire.
Protection.
Fire protection equipment and services made available through governmental authority to all properties within a defined area
Public fire protection.
Local fire alarm system
A detection system, triggered by smoke or heat, that sounds a gong, siren, or another audible alert inside or outside the building
A private detection service that monitors the systems of multiple businesses and/or residences and that calls appropriate authorities or dispatches its own personnel when an alarm is activated
Central station system
Automatic fire sprinkler systems with pipes that always contain water under pressure, which is released immediately when a sprinkler head opens
Wet pipe sprinkler system
Automatic fire sprinkler systems with pipes that contain compressed air or another inert gas that holds a valve in the water line shut until an open sprinkler head releases the gas and allows water to flow through the previously dry pipe to the sprinkler head
Dry pipe sprinkler systems
Automatic fire sprinkler systems with automatic and closed-type sprinkler heads connected to a piping system that contains air or nitrogen, with an additional fire detection system that serves the same area as the sprinklers.
Preaction sprinkler system
sprinkler systems in which the head remains permanently open; when activate by a detection system, a deluge valve allows water into the system.
Deluge sprinkler system
