Fires and Extinguishers

Carbon dioxide is used in the manufacture of sodium carbonate by the ammonia-soda process, urea, salicyclic acid (for aspirin), fire extinguishers and aerated water. Lesser amounts are used to transfer heat generated by an atomic reactor to water and so produce steam and electric power, whilst solid carbon dioxide is used as a refrigerant, a mixture of solid carbon dioxide and alcohol providing a good low-temperature bath (195 K) in which reactions can be carried out in the laboratory. 

Underwriters Laboratories 333 Pfingsten Road Northbrook, Id. 60062 Standards for Safety is ahst of more than 200 standards that provide specifications and requirements for constmetion and performance under test and in actual use of a broad range of electrical apparatus and equipment, including household appHances, fire-extinguishing and fire protection devices and equipment, and many other nongenerady classifiable items, eg, ladders, sweeping compounds, waste cans, and roof jacks for trader coaches. 

A minor incident is one eapable of being dealt with fairly effeetively and quiekly by personnel on the spot using the emergeney equipment, e.g. fire extinguishers and monitors, on hand. The situation ean be dealt with by the workforee, possibly ineluding a Works Fire Brigade, fairly rapidly. It is reasonably loealized and no other unit is affeeted. 

Production in the USA is 350000 tonnes annually of which 30% is used in baking-powder formulations, 20% in animal feedstuffs, 15% in chemicals manufacture, 11% in pharmaceuticals, 9% in fire extinguishers and the remaiiung 15% in the textile, leather and paper industries and in soaps, detergents and neutralizing agents.

Laboratories should have fire extinguishers and safety showers. Respirators should be available for emergencies. Emergency equipment should be kept in a central location and must be inspected periodically. 

Additional temporary protections, e.g., a firewatch with fire extinguisher and emergency notification procedure that includes covering sewer openings, construction of fire boxes of flame resistant material to contain sparks, etc. 

In the coal gasification, as well as in the FT process massive amounts of CO are inevitably produced. CO is the main component of the off-gas in the Sulphur recovery plarft (see above) and in the Benfield plant (which scrubs CO2 from the Synthol tailgas). The latter source is the purer of the two. CO is used in fire extinguishers and the production of "dry ice". 

Bromine (from the Greek bromos for stench ) has found applications in flue gas desulfurization [106], in the design for a large-scale electrical power storage facility [107], in many flame retardants, for fire extinguishers, and in pharmaceuticals. Electrobromination processes have been employed directly and indirectly, and bromates are produced [108] and detected [109] electrochemically. Perbro-mates when compared to perchlorates and periodates are chemically very unstable. A summary of redox states, standard potentials in acidic aqueous media, and typical applications is shown in Scheme 3.

Handle floor-plan questions in the same manner as those on maps. Before attempting to answer any questions, look at the diagram. Familiarize yourself with such features as doors, windows, doorways, patio doors, fire extinguishers, and smoke detectors. Read each question carefully then return to the diagram to find the answer. After you have determined your answer, try to match it to the choices. The correct answer should be apparent, but read each choice carefully to avoid making unnecessary errors. Never jump at one option without carefully reading all the others.
