Building Construction Related to the Fire Service Chapter 1: Building Construction & Fire Service The building variables that FF must consider: • Age of building – age in itself is not a hazard but an indication of potential hazards • Fire protection systems – first line of defense in a building • Occupancy of the building – often affects fire behavior…each occupancy has different hazards & fuels, and the structural components are subjected to different temperatures, heat release, & duration. • Fire/fuel loads – weight of combustibles per sq ft…can be used to determine the total heat release • Type of construction • Configuration – refers to a buildings general shape or layout • Access & exposures…show more content…
& the International Code Council (ICC) National Fire Protection Association The five types of building construction are: Type I – the least combustible building type and considered to be “fire-resistive”. The two most common methods of constructing Type I buildings are by using reinforced concrete or a protected steel frame. The structural members (walls, floors, columns, beams, and roof) are constructed of non-combustible or limited combustible materials that have a specified fire resistance.. These non-combustible materials are defined by the building code that is adopted. The primary fuel load is composed of the contents of the structure. • Bearing walls, columns, & beams a fire-resistance rating of 3-4 hrs • Floor construction 2-3 hrs • Floor construction 1-2 hrs • Partitions usually 1-2 hrs Type II – is similar to type I in construction. Theses buildings are considered “non-combustible or limited combustible” construction. The structural members are allowed to be at a lower fire rating than type I buildings. Type II Construction can be either protected or unprotected. In unprotected construction, the major components are noncombustible but have no fire resistance. Unprotected steel is the most common characteristic in unprotected, noncombustible construction the sub classifications: 222 & 111, have structural components with one or two
