Regulations fire resistance

Polychlorinated biophenyls (PCBs) Heat and fire resistant - extensively used from 1929 and 1977 in electrical transformers All manufacture banned - extensively regulated - very widespread global contaminant... 

Nevertheless, it can be very useful to optimize the burning behavior of a polymer for particular purposes by the addition of fire-resistant materials. These possibilities are presently exploited in various ways in different technical fields, such as the building industry, transport and electric technology. They are usually dependent on the requirements of the relevant national or international safety regulations. 

Hydrogen cylinders should not be stored near oxidizers, and other flammable substances. They should be stored in a cool dry place that is well ventilated, fire resistant and in compliance with federal, state and local regulations. Cylinders should always be stored in an upright position, never on their side, and they should not be rolled on the ground when moving them. The best and easiest way to move a cylinder is with a cylinder cart. 

Fire resistance is an important property of phenolic resins. The combination of phenolic resin with Expancel expandable microspheres leads to many useful products. Composites for high speed train interiors take advantage of the light weight, excellent fire rating, and very low thermal conductivity. Polyester filled with aluminum hydroxide is an alternative solution for train interior materials. The resin and filler can be easily processed when viscosity regulating additives are added. 

The QAP should define record storage requirements with regard to location, time period, security, and format. Paper records are commonly stored in lockable, fire-resistant file cabinets. Active computer records are backed up at frequent intervals to disks or tapes that are stored similarly. After the specified period of years, data files are fransferred to a secure storage location. The time period to ultimate disposal may be controlled by regulations, management policy, or a specific need for records (or lack thereof) after an extended period of time. 

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... 

Haase has extensively reviewed the topic of fire resistant clothing standards and regulations, and Shaw also discussed the use of standards in the selection of protective clothing materials. Horrocks lists many standard test methods for flame resistant textile applications.

Mentioned above is the requirement for some defined level of fire resistance for fibres and assemblies used in most transport sectors to be determined more often than not by national or international regulations that govern their performance requirements. As mentioned above, cars are included because those textile components in internal passenger compartments only such as seating, carpet, seat belts, and internal side and roof lining fabrics require a defined level of flame resistance. 

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. 

The fire resistance is measured in a large-size furnace as described in ISO 834-1975 (E). The temperature rise within the furnace is regulated according to the following time function ... 

Big ships are related to building with respect to their dimensions and construction. Their fire protection concepts are therefore rather similar to those of buildings. For ocean liners, the Inter-Governmental Maritime Consultative Organization (IMCO) issued the regulations International Convention for the Safety of Life at Sea (SOLAS). Chapter II-2 covers the fire protection prescriptions. As for buildings, ships are also divided into fire sectors and fire resistance is codified for particular structural components. Very rigorous requirements are made for the materials used. 

Wiring systems in escape routes - An escape route is the route to follow for access to a safe area in the event of an emergency. Regulation 521.200.1 now requires that wiring systems in escape routes be supported such that they will not be liable to premature collapse in the event of a fire. This will restrict the use of plastic clips and ties, and PVC trunking and conduit as the sole means of support in these areas. Cables in escape routes must be supported or restrained by metallic, fire resistant supports. 

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. 

It is probably evident from the above introductory discussion, and important to realise, that the whole issue of heat and fire protection with respect to textiles is a complex area involving knowledge of elements of fire science, flame retardant treatments, development of heat and fire resistant fibres and derived textile structures and the inter-relationships between regulations, applications and markets. The bibliography lists a number of prime sources of information in these areas, and for an overview of textiles for fire and heat protection the reader should refer in particular to a recent article by this author. In this chapter, the focus will be only on high performance textiles in which fire and heat protection are essential requirements. 

MPDI fabrics have also been used as a fire blocking material in aircraft seat upholstery, where regulations require such functionality. They are finding increasing use as a fire block in hospitals and as upholstery where fire resistance is important. 

As one would expect, fire resistance in polymers is also the subject of both technical standards (121) and government regulation. Organizations such as ASTM, UL, and others have developed a range of standards depending on the polymer and its application. 

Cylinders should be assigned a definite area for storage. The area should be dry, cool, well ventilated, fire resistant, and away from ignition sources. Keep cylinders protected from excessive temperature rise by storing them away from radiators or other heat sources. Storage conditions should comply with local and state regulations.
