Chemical explosives packaged

There are many producers of AN in North America making both AN solution and explosive grade AN prills. The AN solution is used in the manufacture of packaged and bulk emulsion and water gel explosives, and explosive-grade AN prills are used to make ANFO. ANFO, the acronym for a mixture of AN and FO is the single most commonly used chemical explosive. (ANFO is an example of a composite explosive as described in an earlier section, Chemistry of Combustion and Explosions .) These low density AN prills are made by a specialized process, in which internal voids are created making the prills porous and able to absorb the required 5.5-6 percent FO. 

Design separate storage areas for flammable solvents, corrosive liquids, reactive chemicals, explosive chemicals, and chemical carcinogens. Properly inspect chemical containers and packages before use and also periodically. 

Tables 16 and 17 Hst tke analytical test methods for different properties of interest. The Manufacturing Chemists Association, Inc. (MCA) has pubUshed the Chemical Safety Data Sheet SD 63, which describes in detail procedures for safe handling of use of toluene (46). The Interstate Commerce Commission classifies toluene as a flammable Hquid. Accordingly, it must be packaged in authorized containers, and shipping must comply with ICC regulations. Properties related to safe handling are autoignition temperature, 536°C explosive limits, 1.27—7.0 vol % in air and flash point 4.4°C, closed cup.

About two-thirds of the N2 produced industrially is supplied as a gas, mainly in pipes but also in cylinders under pressure. The remaining one-third is supplied as liquid N2 since this is also a very convenient source of the dry gas. The main use is as an inert atmosphere in the iron and steel industry and in many other metallurgical and chemical processes where the presence of air would involve fire or explosion hazards or unacceptable oxidation of products. Thus, it is extensively used as a purge in petrochemical reactors and other chemical equipment, as an inert diluent for chemicals, and in the float glass process to prevent oxidation of the molten tin (p. 370). It is also used as a blanketing gas in the electronics industry, in the packaging of processed foods and pharmaceuticals, and to pressurize electric cables, telephone wires, and inflatable rubber tyres, etc. 

Used industrially as a chemical intermediate in the production of rayon, carbon tetrachloride, xanthogenates, flotation agents, and pesticides used in the cold vulcanization of vulcanized rubber, in adhesive compositions for food packaging as a solvent for phosphorus, sulfur, selenium, bromine, iodine, fats, resins, rubbers, waxes, lacquers, camphor, resins and in the production of optical glass, paints, enamels, varnishes, paint removers, tallow, putty preservatives, rubber cement, soil disinfectants, explosives, rocket fuel, and electronic vacuum tubes. 

A massive explosion and fire occurred at an agricultural chemical packaging facility in Arkansas, killing three firefighters and injuring a fourth. The likely cause was a supersack of azinphos-methyl (an insecticide) being placed near a hot compressor exhaust pipe. 

Nitrogen In the production of ammonia by the Haber process (see p. 176) the ammonia is then used to make nitric acid, which is used in the manufacture of dyes, explosives and fertilisers In liquid form, as a refrigerant As an inert atmosphere for some processes and chemical reactions, because of its unreactive nature for example, empty oil tankers are filled with nitrogen to prevent fires In food packaging to keep the food fresh, for example in crisp packets where it also prevents the crisps being crushed (Figure 11.10)... 

Renewable energy processes include the operation of combustion and H2-handling systems and therefore have to be protected against fires (see Section 3.8) and explosions. Because chemicals display different explosive characteristics and processes differ in physical dimensions, an explosion suppression system is usually a design package. In many instances, approval for insurance must be obtained from fire underwriters with evidence of design capability demonstrated in a test. 

The businesses of chemicals, coatings and plastics are closely linked, and those sectors, in turn, are closely linked to the oil and gas industry. Plastics comprise a branch of petrochemicals—that is, chemicals refined from petroleum. Total world consumption of oil for industrial uses is about 30 million barrels daily—mostly for use in chemical processes. Coatings, which include paints, are chemical concoctions. Other everyday chemicals products include pharmaceuticals, fertilizers, dyes, fibers, packaging, adhesives and explosives, among...
