In addition to spacing criteria, many standards provide requirements for building design and construction to provide fire resistance and protect occupants. Table 3.2 summarizes typical key references for fire protection and evaluation.

For enclosed process structures, open outside stairs may be used for an exit, but require protective separation from the interior of the building by walls with the same fire resistance rating as required for enclosed stairs. This construction should extend vertically from the ground to a point 10 ft (3 m) above the topmost landing of the stairs or to the roofline, whichever is lower, and to a point not less than 10 ft (3 m) horizontally. 

Separation distances are also important. Aboveground storage tanks must be separated from buildings, property lines, fuel dispensers and dehvery trucks in accordance with the level of safety the tank design provides, depending upon whether they are constructed of traditional steel or are vault/fire-resistant. 

Fire Resistive Material and design of building construction meant to withstand the maximum effect of a fire for a specific period of time. 

F. Buildings constructed of such steel can collapse from the heat of the fire. The word heat-resistant is used in this relation. Heat-resistant, therefore, as used here refers to the thermal conductivity of the fire-protective medium, the mastic. 

In the building field, as fire-resistant coating for wood, fiberboard, and metals, they have numerous applications. Unusual usage of the fire-resistant mastics is their application against brush fires on railway trestles constructed of wood which had been impregnated with as much as 3 gallons of creosote-petroleum oils per cubic foot.

Chapter 6 Types of construction. The permission to use combustible materials or the type of fire resistance ratings are a function of whether the building is constructed completely, or primarily, of noncombustible materials. 

Chapter 7 Fire resistant-rated construction. This chapter addresses the separation requirements between rooms/compartments in buildings and between buildings, and also deals with insulation.

The fire death rate in the United States is decreasing, dropping from a rate of 76 per million in the 1940s, when most construction and decorative products were made of natural materials, to 29 per million in the 1980s, by which time, PVC had replaced natural materials in numerous applications (189). This downward trend can be attributed in laige part to improved building codes and the broader use of sprinkler systems and smoke detectors. However, the increased use of more fire-resistant materials, such as PVC, deserves part of the credit for this improvement. 

Regardless of construction type, building construction generally falls into one of three categories fire resistive, noncombustible or combustible. These categories are described in Table 6-5 along with a reference to a construction classification. 

The example identifies a U.S. construction classification based upon NFPA 220, Types of Building Construction. The Arabic numbers following each type of construction (e.g. Type I, II, etc.) indicate fire resistance ratings for certain structural elements. The first number addresses exterior bearing walls. The second number addresses the structural frame when supporting more than one floor. The third number addresses floor construction. Other construction codes have similar and more detailed classifications. 

Moderate Fire-resistant Construction. Buildings having masonry walls with heavy timber or unprotected metal support structures. 

Good Fire-resistant Construction. Buildings with masonry, protected steel, or reinforced-conCrete construction.
