Fire extinguisher chemicals

Uses Aerosol propellant refrigerant solvent blowing agent for polyurethane foams fire extinguishing chemical intermediate organic synthesis. 

Safety requires you to think in advance about what you will do never do anything that seems dangerous. Know how to use safety equipment such as goggles, fume hood, lab coat, gloves, emergency shower, eyewash, and fire extinguisher. Chemicals should be stored and used in a manner that minimizes contact of solids, liquids, and vapors with people. Environmentally acceptable disposal procedures should be established in advance for every chemical that you use. Your lab notebook tells what you did and what you observed it should be understandable to other people. It also should allow you to repeat an experiment in the same manner in the future. You should understand the principles of operation of electronic and mechanical balances and treat them as delicate equipment. Buoyancy corrections are required in accurate work. Burets should be read in a reproducible manner and drained slowly for best results. Always interpolate between markings to obtain accuracy one deci-...

MAJOR USES Used in pharmaceutical products used as a solvent for adhesives, pesticides, rubbers, fats, oils, alkaloids, resins cleansing agent dry cleaning agent used in fire extinguishers chemical intermediate for fluorocarbon, dyes, pesticides, tribromomethane. 

OTHER COMMENTS used as an aerosol propellant also used in refrigeration machinery requiring a refrigerant effective at negative pressure other uses include a blowing agent for polymeric foams, fire extinguishers, chemical intermediate, and use as a solvent. 

On-site fire suppression/extinguishing system - the system used to extinguish or suppress a fire in fire-protected plant areas. At some NPPs, a water sprinkler or spray only is used. At other NPPs, fire-extinguishing chemicals can also be used in selected areas, either to increase fire suppression system efficiency, or to protect sensitive electronic equipment from water intrusion. Data providers should choose the appropriate option from the multiple-choice menu water sprinkler only, water + supplementary chemical systems.

Production and Shipment. Estimated adiponitrile production capacities in the U.S. in 1992 were about 625 thousand metric tons and worldwide capacity was in excess of lO metric tons. The DOT/IMO classification for adiponitrile is class 6.1 hazard, UN No. 2205. It requires a POISON label on all containers and is in packing group III. Approved materials of constmction for shipping, storage, and associated transportation equipment are carbon steel and type 316 stainless steel. Either centrifugal or positive displacement pumps may be used. Carbon dioxide or chemical-foam fire extinguishers should be used. There are no specifications for commercial adiponitrile. The typical composition is 99.5 wt % adiponitrile. Impurities that may be present depend on the method of manufacture, and thus, vary depending on the source. 

Shipment. The DOT/IMO shipping information is shown in Table 6. Approved materials of constmction for shipping, storage, and associated transportation equipment are lined carbon steel (DOT spec. 105 S 500W) and type 316 stainless steel. Water spray, carbon dioxide, chemical-foam, or dry-chemical fire extinguishers may be used. 

Some dry-chemical fire extinguishers contain sodium or potassium bicarbonate these should not be used on nitromethane or nitroethane fires. Dry chemical extinguishers can be used on nitropropane fires. 

Most dry-chemical fire-extinguishing materials also function by inhibiting combustion rather than by cooling or by reducing oxygen concentration. The usual dry-chemical material is a bicarbonate, but some phosphates, eg, ammonium, provide a coating that makes the material suitable for use on fires involving soHd combustibles such as mbber tires, wood, and paper. 

An important use of bromine compounds is in the production of flame retardants (qv). These are of the additive-type, which is physically blended into polymers, and the reactive-type, which chemically reacts during the formation of the polymer. Bromine compounds are also used in fire extinguishers. Brominated polymers are used in flame retardant appHcations and bromine-containing epoxy sealants are used in semiconductor devices (see... 

When heated to about 60°C, nickel carbonyl explodes. Eor both iron and nickel carbonyl, suitable fire extinguishers are water, foam, carbon dioxide, or dry chemical. Large amounts of iron pentacarbonyl also have been reported to ignite spontaneously (189). Solutions of molybdenum carbonyl have been reported to be capable of spontaneous detonation (190). The toxicity of industrial chemicals including metal carbonyls may be found in references 191-194. 

Fire Hazard. Although chlorosulfuric acid itself is not dammable, it may cause ignition by contact with combustible materials because of the heat of reaction. Open fires, open lights, and matches should not be used in or around tanks or containers where hydrogen gas may be collected because of the action of chlorosulfuric acid on metals. Water, carbon dioxide, and dry-chemical fire extinguishers should be kept readily available. 

Powder Costings. Epoxy-based powder coatings exhibit useful properties such as exceUent adhesion, abrasion resistance, hardness, and chemical resistance. The appHcation possibUities are diverse, including refrigerator liners, oU filters, hospital equipment, primers, shelving, automobUe springs, and fire extinguishers. 

If an ethyl ether fire occurs, carbon dioxide, carbon tetrachloride, and dry chemical fire extinguishers meeting National Eire Prevention Association Code 1 and 2 requirements may be used successhiUy (23). Water may also be effectively appHed (see Plant safety). Hose streams played into open tanks of burning ethyl ether serve only to scatter the Hquid and spread the fire. However, ether fires may be extinguished by a high pressure water spray that cools the burning surface and smothers the fire. Automatic sprinklers and deluge systems are also effective.
