Clinical laboratories deal with each of the nine classes of hazardous materials. These are classified by the United Nations (UN) as (1) explosives, (2) compressed gases, (3) flammable liquids, (4) flammable solids, (5) oxidizer materials, (6) toxic materials, (7) radioactive materials, (8) corrosive materials, and (9) miscellaneous materials not elsewhere classified. Shipping and handling of Class (6) toxic materials,... 

The subsections that follow cover the hazards associated with the various materials used and produced in a chlor-alkali plant. These include chlorine, hypochlorites, caustic soda and potash, hydrogen, hydrochloric acid, sulfuric acid, mercuiy, asbestos, nitrogen trichloride, and miscellaneous materials. 

Transportation instmctions require DOT Hazard Class in which materials are divided into the following classes 1 - Explosives, 2 - Gases, 3 - Flammable and combustible liquids, 4 - Flammable spontaneously combustible solids, 5 - Oxidizers organic peroxides, 6 - Poisonous infectious materials, 7 - Radioactive materials, 8 - Corrosives, 9 - Miscellaneous. In addition UN number and packaging group is also given.

J Materials used to fabricate miscellaneous, discontinuous small parts (such as knobs, rollers, fasteners, clips, grommets, and small electrical parts) that will not contribute materially to fire growth in end-use configuration are exempt from flammability and smoke emission performance requirements, provided that the surface area of any individual small part is less than 16in.2 (100 cm2) in end-use configuration and an appropriate fire hazard analysis is conducted which addresses the location and quantity of the materials used, and the vulnerability of the materials to ignition and contribution to flame spread. 

The hazard classes recognized by the DOT are Class 1, Explosives Class 2, Compressed Gases Class 3, Flammable Liquids Class 4, Flammable Solids Class 5, Oxidizers Class 6, Poisons Class 7, Radioactives Class 8, Corrosives and Class 9, Miscellaneous Hazardous Materials. Class 1 Explosives are subdivided into six subclasses 1.1 through 1.6. Class 2 Compressed Gases have three...
