Contents of the structure Interior finishes Difficult to ventilate Difficult to breach for access or escape
Same as Type I, except that structural components lack the insulation or other protection. All metal buildings fall into this classification Materials without fire resistive ratings may be used in limited quantities Often have flat, built up roofs
Contents of structure Interior finishes Fire extension to the roof can eventually cause the entire roof to fail Unprotected structural steel components may fail due to heat
Exterior walls or structural members are made of non-combustible or limited combustible materials Interior structural members are completely or partially made of wood Relatively easy to vertically ventilate Resists fire spread from the outside For instance… This station.
Fire spreads through concealed spaces Interior structural members vulnerable to fire Susceptible to water damage
Interior and exterior walls made of non- combustible or limited combustible materials Other interior structural members are made of solid or laminated wood with no concealed spaces Used in old factories, mills, warehouses, and old churches… ski lodges… log homes etc.
Massive amount of combustible contents can produce massive amounts of heat Susceptible to fire spread from the outside Susceptible to water damage
Structural components are made completely or partially of wood or other approved materials Commonly used to construct typical single family residences and apartment buildings up to seven stories. Easily breached for access, ventilation, or escape Resistant to collapse from earthquake
Susceptible to fire spread from the outside and in. Susceptible to total collapse due to fire or explosion Contents of structure (Furniture, Carpet etc. burn hot and produce large amounts of toxins Lightweight wooden trusses
Many parts of North America allow non- standard buildings to be constructed under certain circumstances. Structures do not conform to any of the standard construction types Usually found on large properties in remote areas One example is hay bale construction Name another non-standard construction example…?
