Chemical industry post-1945 period

That is quite an accomplishment. Granted, some industries have made immense fortunes over the same period, which many chemicals players have not in 1980, Microsoft was just launching MS-DOS, Cisco Systems had not yet been founded. The advance of computerization, electronics, and new technology has seen the core businesses of a number of sectors transformed - apart from the IT world itself, pocket calculators, cash registers, and the world of home entertainment are cases in point. The pharmaceutical industry and financial institutions also created a great deal of wealth in this period. However, some other major players, particularly telecommunications, have seen enormous value destroyed following the post-deregulation boom. [Pg.53]

This presentation examines how the chemical engineer translated proposals into manuflicturing plants and so enabled the armed forces to obtain their essential supphes of explosives and propellants on a massive industrial scale. It is convenient to divide the history of the industry into five epochs broadly defined as the period leading up to World War I and including the years of the Boer War the 1914-1918 War the post-war years up to 1935 when rearmament began from 1936 to the end of World War II and the post World War II period up to the present day. The five epochs and the products prepared during them are outlined in Figure 1. [Pg.368]

Laboratory hoods should be inspected at least every three months. The CHO, industrial hygienist, or designated technician should measure the face velocity of hoods periodically to ensure that 75 to 125 feet per minute (0.4-0.6 ms 1) air velocity is maintained. The sash opening height should be properly marked to indicate the face velocity. A transport velocity in the exhaust duct of the hood of 3500 feet per minute (18ms 1)is recommended. A record of the inspection should be dated and posted at the hood. Prior to a change in chemicals or procedures, the adequacy of the ventilation system and the suitability of the hood for the new process must be evaluated. [Pg.302]
