legal document that govern activities at various levels of government
codes
describes a set of requirements that are similar to a standard; only enforceable when the AHJ adopts them
model codes
When are model codes enforceable
when the AHJ adopts them
a document that a committee of experts has developed and agreed upon before publication
consensus standards
What determines a the “type” of building construction
the construction materials used and their resistance to fire
Types 1 b/c is composed of what kind of structural members?
non / limited combustible with high fire resistance (i.e. reinforced concrete, precast concrete, and protected steel frame)
Is type 1 construction fireproof?
No; the structural members will not burn, but they may degrade from the effects of fire
What are the concerns associated with type 1 b/c and fire?
compartments that retain heat, roofs that may be difficult to penetrate, non operating windows
what is the difference between fire-resistive & noncombustible construction?
the material of type II do not meet stricter requirements than those materials used in type I (they still do not add to the fuel load)
what are common components of a type II construction?
metal framing, metal cladding, concrete block wall, unprotected, open web joists supporting metal roof decking
what are common components of type III construction?
exterior wall and structural members of non/limited combustibles and interior walls, columns, beams, floors and roofs are completely / partially wood
name concerns with Type III
fire spread through void spaces of the roof and truss system
lack of fire stops in void spaces
prefab wood truss systems similar to Type V
in what way are type IV buildings resistive to collapse?
sheer mass of the structural members
the timbers own char reduces heat penetration to the inside of the beam
what are common components of type IV
exterior wall of noncombustible materials
interior floors, walls, roofs are solid / laminated wood with no concealed spaces
Type IV buildings exhibit what conditions that can affect fire behavior
high wood concentrations
collapse of masonry walls caused by loos of structural integrity of timbers
what is the most common type of factory built home?
manufactured (mobile); have an axle assembly under the frame
(T/F) manufactured homes are not required to conform to model building codes
True; required to meet HUD standard, which is similar to type v
The HUD code (blank) all building codes and is (blank) stringent than model building codes
preempts; more
what may be an additional sources of oxygen during a fire in a factory built home?
an open crawl space
why does fire spread quicker in a manufactured home?
fewer interior walls to create compartments and interior wall finishes, causing the fire to quickly become even limited
in what year was the HUD standard enacted?
1976
A compartment or structure that is used for the gathering of 50 or more persons (worship, theaters, restaurants, arenas)
Assembly occupancy
An occupancy that provides a workspace for large numbers of occupants in an office environment
Business
structure used by six or more persons through the 12th grade that meets for four or more hours in a day or more than 12 hours in a week; also encompasses days cares for 6 or more 2.5 y.o.
Educational
any building that is designed to sell or display merchandise
mercantile
any occupancy that provides sleeping accommodations other than those defined for health care, detention, or correctional (1-2family, lodging, hotel, dorm, apartment)
residential
occupancies used to store goods, merchandise, vehicles, or animals
storage
situations in which a variety of occupants may be included in the same structure
Mixed
designed to trigger an alarm when a fire or potential fire is detected
fire detection and alarm system
activated manually; sensor that detect heat, smoke or flame can also activate them; INITIATE AN ALARM SIGNAL ONLY ON THE PREMISE WHERE THEY ARE INSTALLED, DO NOT TRANSMIT A SIGNAL; primary purpose is to notify building occupants, then passerby’s
local
used only in communities that have municipal alarm box systems; installed in a building a connect to box alarm at street, transmits signal to fire dept
auxiliary
connect directly to the comms / dispatch center; may cover up to 5 buildings
remote station
used to protect large commercial and industrial buildings, high rise buildings and groups of commonly owned buildings in a single location; common receding point somewhere on the premises
proprietary
receiving point is not on the protected premises, the owner does not employ the person receiving the alarm
central station
Are almost always electrically driven centrifugal pumps with a discharge capacity from 500 - 4500 gpm (NFPA 20)
Stationary fire pumps
standpipe system intended for firefighting use
Class I
standpipe system designed for use by trained building occupants or FD; equipped with 1.5” hose or nozzle
Class II
