Building construction noncombustible

Building Construction. All compressor station buildings that house hydrogen gas piping or equipment handling hydrogen gas shall be constructed of noncombustible or limited combustible materials. 

Active external fire exposure protection for control buildings is seldom needed since the primary protection is the passive spacing distance between the building and the process areas and the building s noncombustible construction. 

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. 

Refers to properties of materials or designs to resist the effects of any fire to which the material or structure may be expected to be subject. A building constructed of fire-resistive materials can withstand a burnout of its contents without subsequent structural collapse. Fire resistive implies a higher degree of fire resistance than noncombustible. 

All site buildings and structures are constructed of noncombustible materials, particularly exteriors and structural support systems. 

Compressors should preferably be located outdoors or, alternatively, in buildings of totally noncombustible construction with adequate ventilation. Concrete or concrete-on-protected-steel should be used for a compressor system supporting structure. Exposed steel construction is acceptable if protected by water spray or deluge system. 

Only noncombustible materials should be used in the construction of control room buildings. While walls of masonry construction offer greater protection from external fire exposure, control buildings can be of pre-engineered construction if fire or explosion exposure is minimal. When the possibility of damaging explosion overpressure exists, the entire building design must be carefully evaluated. 

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. 

Temporary buildings, when located within another building or structure, shall be of either noncombustible construction or of combustible construction having a fire resistance of not less than 1 hour. 

B) Tanks may be built of materials other than steel for Installation underground or if required by the properties of the liquid stored. Tanks located above ground or inside buildings shall be of noncombustible construction. 

Buildings shall be of noncombustible construction or sheet metal on wood studs. 

Construction. Buildings in an HPR facility need to be of superior construction. Today, fire resistive, heavy noncombustible, or light noncombustible construction is preferred. Masonry plank on timber or steel is an early example of superior construction. It would allow substantial time before collapse to accommodate manual fire fighting. 

Process-unit control houses should be located at the periphery of the process unit. The structural members and the interior and exterior walls of control buildings should be constructed of noncombustible materials.
