Fire precautions manufacture

The Secretary of State has powers under the Act to make regulations about fire precautions in designated premises other than those in which manufacturing processes are carried on (s. 12). 

These and the numerous associated Orders and Regulations cover the manufacture, storage, carriage and use of explosives, licensing and registration of premises, fire precautions, etc. 

Personnel rmdertaking decontamination need proper training they should wear appropriate PPE and should ertsirre siritable fire precautions are taken. More specific information should be sought from MSDS and suppliers, importers or manufacturers. Accidents have occrrrred for example, when people have cut containers, which have held isocyanate ingredierrts for polymethane foam manufacture, fuel or bitumen (asphalt), with an oxyacetylene torch. Some containers such as gas cylinders are, of comse, recycled through the suppliers.

The best defense for a manufacturer is to ensure that the precautions taken at every stage were such that a manufacturer has gone the extra mile, and investigated the materials or products being sold beyond the specifications. In particular, when deficiencies of certain techniques (e.g., fire tests)... 

SAFETY PRECAUTIONS - Very stable, but should be made up as needed. AN should be kept dry to ensure proper detonation. This explosive is a definite fire hazard. Flame and heat should be avoided. Not shock sensitive as explosives go, but can be detonated by a very sharp blow (30cm drop of a 2 Kg. weight will detonate). Copper and brass should be avoided in manufacture and all munitions loading and finished products. 

Keep away from heat. Wear protective gloves and eye/face protection as specified by the manufacturer/supplier or the competent authority.

(in accordance with local/regional/national/intemational regulation). 

Consequently, manufacturers handling such fine powders must take special precautions against fires and explosions. 

When all the CaO has been added, the stirring is continued at a more leisurely pace for another three hours. This long stretch of stirring is bound to tire even the most dedicated explosive manufacturer so an alternative which can be used where electricity is available is to suspend an electric drill or similar motor over the pail, and use a clean paint stirrer attachment to stir the solution. The fumes are not especially flammable, so fires are not the hazard they often are when dealing with more flammable chemicals. Even so, rigging an extra long stem for the stirrer, so the motor is elevated above the pail rim, is a wise precaution. 

The vapors of the organic solvents used in the preparation of cellulose ester solutions represent a potential fire, explosion, or health hazard. Care should be taken to provide adequate ventilation to keep solvent vapor concentrations below the explosive limits. Mixing equipment should be designed to ensure that solvent temperatures do not approach their flash point during the mixing cycle. All equipment must be electrically grounded to prevent static discharge, and appropriate precautions should be followed as recommended by the manufacturer of the solvents.

Product labels include details of the hazards associated with the substances contained in the product and any precautions recommended. They may also bear one or more of the CHIP hazard classification symbols. Product safety data sheets are another very useful source of information for hazard identification and associated advice. Manufacturers of hazardous substances are obliged to supply such sheets to users giving details of the name, chemical composition and properties of the substance. Information on the nature of the hazards and any relevant standards (WEL) should also be given. The sheets contain useful additional information on first aid and fire fighting measures and...
