Q

Type I (Fire-resistive)

A

This type of construction provides the highest level of protection from fire spread as well as structural collapse. All structural members are composed of noncombustible or limited-combustible materials with a high fire-resistive rating so that the structural members do not add to the fuel load.

Q

Type II (Noncombustible)

A

This type is composed of materials that will not contribute to the fire development or spread. Do not add to the fuel load. Includes metal framing members, metal cladding, or concrete block wall construction, and unprotected, open web joists supporting metal roof decks.

Q

Type III (Ordinary construction)

A

commonly found in mercantile, business, and residential structures and older schools. Requires that exterior walls and structural members be constructed of noncombustible or limited combustible materials. Interior walls, columns, floors, and roofs, are completely or partially constructed of wood.

Q

Type IV (Heavy Timber)

A

characterized by the use of large dimension lumber or laminated wood. The dimensions of all elements, including columns, beams, joists, and girders, must adhere to minimum dimension sizing. They are stable and resistant to collapse.

22
Q

Rating assigned to a material or assembly after standardized testing by an independent testing organization; identifies the amount of time a material or assembly will resist a typical fire, as measured on a standard time-temperature curve.

A

Fire-Resistance rating

23
Q

Solid materials, such as wood blocks, used to prevent or limit the horizontal or vertical spread of fire and products of combustion in hollow walls or floors, above false ceilings, in penetrations for plumbing or electrical installations, in penetrations of a fire-rated assembly, or in cocklofts and crawl spaces.

A

Fire stop

24
Q

Fire-rated wall with a specified degree of fire resistance, built of fire-resistive materials and usually extending from the foundation up to and through the roof of the building; designed to limit the spread of fire within a structure or between adjacent structures.

A

Fire Wall

25
Q
