Structure Fire

Structures are divided into five construction types for the purposes of firefighting, and are listed from least combustible to most combustible:

Type I: Fire Resistant: Typically used in hi-rises. Fire resistant protection is applied to steel members of the construction.

Type II: Non-Combustible: Typically used in strip shopping center malls. Roofs are constructed out of steel rafters.

Type III: Ordinary Construction: Brick and mortar walls, wood frame floors. City rowhouses are where this type of construction is most often found.

Type IV: Heavy Timber: Often used in churches or other community based buildings.

Type V: Wood Frame: Typically used in recent construction of single family dwellings, townhouses, garden apartments with four floors or less.
