Fire regulations

The materials of construction, from the cupboard to the fan, should be inorganic and resistant to attack by perchloric acid. For the cupboard itself suitable materials include stainless steel of types, 316 or 317, solid epoxy resin, and rigid PVC. Stainless steel has been popular for this application as it is easy to form, weld, and polish. It is, however, attacked by the acid, which causes discoloration of the metal surface and the formation of iron(III) perchlorate, which can be explosive. Ductwork, separate from other extract systems, is usually made from stainless steel or plastic materials. Fire regulations may preclude the use of plastic ductwork or require it to be sheathed in an outer casing of metal or GRP. The fan casing and impeller can both be made of plastic.

The key parameters to be considered for structural protection include the usual fire protection standards and the specific authorities governing fire regulations the nature, the location, and the critical temperature of the substrate protected are also essential parameters. Finally, the conditions that the protection is required to resist during its service life have also to be considered. 

The standards listed above are the most commonly used standards. However, national authorities governing fire regulations can play a significant role and add more specific standards for... 

Recently, two significant developments have raised the profile of fire toxicity. The first is the development of the steady-state tube furnace (SSTF) (ISO TS 19700 2006), which has been shown to replicate the toxic product yields corresponding to the individual stages of fires. The second is the acceptance of performance-based fire design as an alternative to prescriptive fire regulations, so that architects can specify the components within a building based on a safe escape time, within which toxic and irritant gas concentrations must not approach a lethal level (ISO 13571 2007).

In addition to good, storage facilities exceed the minimum fire regulations and containers are always labelled. A strong policy is in evidence relative to the control of the handling, storage and use of flammable materials... 

Due to more stringent fire regulations in many countries and the increased use of plastic materials and synthetic fibres, the use of flame retardants has increased. In 1992,600,000 tons of flame retardants were used worldwide, 150,000 tons were brominated compounds. 50,000 Tons of these were the reactive flame retardant with TBBPA and its derivatives and 40,000 tons were PBDEs [1]. 

Flame Retardants. Among the isocyanate-based foams, polyurethane foams, both flexible and rigid, are flammable. Due to serious fire hazards of polyurethane foams, strict fire regulations have come out on the use of foams in the areas of furniture and public transportation. In addition, the use of rigid urethane foams in building insulation have resulted in stricter fire regulations. 

Thus the flash point is used primarily as an index of fire hazards. Consequently, most industry specifications or classifications place limits on the flash point to ensure compliance with fire regulations, insurance, and legal requirements because it is essential that the fuel is safe to transport and store. Generally, because of its distillation characteristics, fuel oil should not contain any volatile or flashable constituents. Nevertheless, the occasion might arise when application of test methods to determine the flash point might be applicable.

The common matrix materials in FRP composites are flammable. However, FRP composites in buildings must meet the relevant fire regulations. The requirement of FRP composite components to be fire-resistant can generally be met by applying a gel coat, by putting appropriate additives in the matrix, or through the inclusion of fire-retardant core materials... 

Doors opening onto fire resistant-rated corridors and stairways must be self-closing or close automatically in the event of a fire. The first of these requirements usually includes offices opening directly off corridors, and is the case alluded to earher as representing one of the most commonly violated fire regulations. For whatever reason, most individuals usually prefer to work with their office door open. Unfortunately, in an emergency evacuation, many do not remember to close their doors, and so the integrity of the fire separation is breached at these points.

Polystyrene foams applied in building constructions are dealt with in BS 6203 1982. No particular test procedure is prescribed, reference is made only to flammability tests in the building industry, mainly according to BS standards, the properties of polystyrene foams are surveyed, and proposals are made as to the most effective ways of their incorporations into building structures with respect to fire regulations. 

Accordingly, this Chapter covers the methods for reducing the flammability of plastics, fire-fighting techniques against burning plastics, and it includes a brief survey of fire regulations for the applications of plastics. 

Sommer [16] has discussed the suitability of halogen-free fire retardant systems from meeting the specifications of fire regulations in the building, rolling stock and electrical industries. 

There are three simulation cases for engine fire scenario. The first one is ideal condition for fire where ventilation is switched off when fire breaks out, in accordance with the current fire regulation. In this case, fire will be contained in the engine room compartment and it will burn itself out in short period of time due to lack of oxygen with minimal effects on cargo hold compartment. 

Where cables pass through walls, floors and ceilings the hole should be made good with incombustible material such as mortar or plaster to prevent the spread of fire (Regulations 527.1.2 and 527.2.1). Cables passing through metal boxes should be bushed with a rubber grommet to prevent abrasion of the cable. 

Because of this, in most countries the fire regulations specify periods of fire resistance, as measured in a standard fire-test for load-bearing elements, depending upon the size and function of the building. They tend to concentrate on passive rather than active methods of protection, and the required periods of fire resistance are frequently listed in a tabular format relating periods of fire resistance to maximum compartment dimensions and building height for various types of occupancy. 

What are the current trends and innovations First of all, demand for flame retardants will rise worldwide on account of stricter fire-safety levels. It will be spurred on inter alia by the harmonisation of fire protection requirements for products in the constmction industry and for railway rolling stock within Europe, as well as through the introduction and implementation of fire regulations in newly industrialised countries, especially in Asia, with particular focus on China. The 42V power supply in cars and UL94 V-0 television sets in Europe will similarly contribute towards this trend. Over the medium term, US fire safety requirements could be imposed on upholstered furniture in the private sphere throughout the entire country, which would ensure a boom in the demand for flame retardants.
