Fire protection building materials

Radiant heat can be calculated using the SFPE Handbook of Fire Protection Engineering (Ref. 40) or CCPS s Guidelines for Evaluating the Characteristics of Vapor Cloud Explosions, Flash Fires, and BLEVEs (Ref. 5). If the expected radiant heat load exceeds the capacity of the building materials to resist it, further evaluation should be performed. References 104 and 105 provide additional guidance on fire. 

Steel, aluminum, concrete, and other materials that form part of a process or building frame are subject to structural failure when exposed to fire. Bare metal elements are particularly susceptible to damage. A structural member undergoes any combination of three basic types of stress compression, tension, and shear. The time to failure of the structural member will depend on the amount and type of heat flux (i.e., radiation, convection, or conduction), and the nature of the exposure (one-sided flame impingement, flame immersion, etc.). Cooling effects from suppression systems and effects of passive fire protection will reduce the impact. 

Typically, medium to small processing facilities are under the jurisdictional coverage of local fire and building codes that require automatic sprinkler protection. These processing operations should be fire protected by automatic sprinklers that extend overall areas that store, process, or transfer flammable or combustible materials. The physical limits of the areas requiring protection can... 

Pumps handling flammable materials represent a significant potential for spill and subsequent fire. This is due to damage to seals and failures of other potential leak points. The first consideration in fire protection for pumps is their location relative to other equipment, vessels, process structures and buildings housing personnel, and key control or utility systems. When locating a pump, consideration should be given to the size, properties of material handled, temperature, and pressure.

The technical suitability of insulation materials is described by a series of technical parameters relating to the material (heat conductivity and heat storage capacities, damp protection, fire protection class, noise-insulating effect, properties related to building biology, e g. content of hazardous substances such as flame retardants and insecticides). Mineral wools have certain advantages over other insu-... 

Buildings constructed between 1930 and 1950 may contain insulation made with asbestos. Wall and ceiling insulation that contains asbestos is generally found inside the wall or ceiling ( sandwiched behind plaster walls). The asbestos is used as material for thermal insulation, acoustical insulation, and fire protection. Renovation and home improvements may expose and disturb the materials. 

Fites and Explosions in Industries (Prevention, Protection and Extinction). In order to have fire, there must be present a combustible material (such as wood, coal, fuel oil, etc), an oxidizing agent (such as oxygen, nitrates, chlorates, perchlorates, peroxides etc), and sufficient heat to start the fire. If buildings are constructed of wood or cardboard, they provide enough combustible material to start a fire... 

As mentioned earlier, the fire hazard of interior finish materials is primarily due to the potential for rapid wind-aided flame spread over the surface. It is therefore not a surprise that reaction-to-fire requirements for interior finish materials in U.S. building codes are primarily based on performance in a wind-aided flame spread test. The apparatus of this test is often referred to as the Steiner tunnel. The Steiner tunnel test is described in ASTM E 84. Although the test does not measure any material properties that can be used in a model-based hazard assessment, a discussion of the test is included here due to its practical importance for the passive fire protection of buildings in the United States.

Efficient fire protection is also based on the consideration of product or scenario-specific hazards, which may lead to very specific materials development goals. Examples are the combination of impacts, such as vandalism and ignition source for seats in railway vehicles, or a preceding shock wave before the fire impact in navy applications. Some more product-specific phenomena of such kind are related directly to material properties, such as building up an increased risk for pool fires through burning thermoplastic plastics or dripping foams, and thus have become topics in the development of some flame-retarded materials.103... 

Poiybrominated benzenes (PBBz) and poiybrominated biphenyls (PBBs) have been widely used as flame or fire retardants. The use of flame retardants is recommended or required in diverse areas such as synthetic polymers which are used in building materials, textiles, packing materials, electric applications, automobile manufacturing etc. to protect the public from fire accidents [247,248]. PBBs were introduced as flame retardants in the early 1970s. In Japan e.g. the aimual con-...

The utilization of docks depends on two factors the turnaround time to load or unload and the arrival pattern of trucks at the docks. Typically, the dock utilization should be 70-80%. Also, the use of proper dock equipment is evaluated. Dock locks or chocks, levelers, and light should be available. Lighting should not only be sufficient to support operations but also be located properly to avoid equipment interferences. Personnel services should be properly located and of sufficient size and quantity to support the staff. Fire protection is rated based on the type of facility, the equipment methods used, and the type of material stored. Outside space is most often overlooked in building facilities. Proper allowances for truck access, personnel access, and other services can affect safety and efficiency. 

Housekeeping as used here includes indoor and outdoor plant care and maintenance. It extends to every part of the plant (offices, processing areas, laboratories, etc.) a fire that starts in an office area may be equally as serious as one that starts in the plant area. These topics are considered in great detail in the NFPA Fire Protection Handbook All personnel should be familiar with the material applicable to their operations. In addition, the safety committee should consider housekeeping practices in its inspection procedures. Of particular interest are building and plant care and maintenance, indoor and outdoor storage (manner of storage compatibility and...
