　　Which is safer-staying at home, traveling to work onpublic transport, or working in the office?Surprisingly, each of these carries the same risk,which is very low. However, what about flyingcompared to working in the chemical industry?Unfortunately, the former is 65 times riskier than thelatter! In fact, the accident rate of workers in the chemical industry is less than that of almostany of human activity, and almost as safe as staying at home.

　　The trouble with the chemical industry is that when things go wrong they often cause death tothose living nearby. It is this which makes chemical accidents so newsworthy. Fortunately,they are extremely rare. The most famous ones happened at Texas City (1947),Flixborough(1974), Seveso (1976), Pemex (1984) and Bhopal (1984).

　　Some of these are always in the minds of the people even though the loss of life was small. Noone died at Seveso, and only 28 workers at Flixborough. The worst accident of all was Bhopal,where up to 3,000 were killed. The Texas City explosion of fertilizer killed 552. The Pemex fireat a storage plant for natural gas in the suburbs of Mexico City took 542 lives, just a monthbefore the unfortunate event at Bhopal.

　　Some experts have discussed these accidents and used each accident to illustrate a particulardanger. Thus the Texas City explosion was caused by tons of ammonium nitrate(硝酸铵),which is safe unless stored in great quantity. The Flixborough fireball was the fault ofmanagement, which took risks to keep production going during essential repairs. The Sevesoaccident shows what happens if the local authorities lack knowledge of the danger on theirdoorstep. When the poisonous gas drifted over the town, local leaders were incapable oftaking effective action. The Pemex fire was made worse by an overloaded site in anovercrowded suburb. The fire set off a chain reaction os exploding storage tanks. Yet, by amiracle, the two largest tanks did not explode. Had these caught fire, then 3,000 strongrescue team and fire fighters would all have died.
