[单项选择]passage one
Which is safer-staying at home, traveling to work on publictransport, or working in the office Surprisingly, each of thesecarries the same risk, which is very low. However, what aboutflying compared to working in the chemical industryUnfortunately, the former is 65 times riskier than the latter! Infact, the accident rate of workers in the chemical industry is lessthan that of almost any of human activity, and almost as safe asstaying 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 areextremely 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 fire at astorage plant for natural gas in the suburbs of Mexico City took 542 lives, just a month before theunfortunate 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),whichis safe unless stored in great quantity. The Flixborough fireball was the fault of management,which took risks to keep production going during essential repairs. The Seveso accident showswhat happens if the local authorities lack knowledge of the danger on their doorstep. When thepoisonous gas drifted over the town, local leaders were incapable of taking effective action. ThePemex fire was made worse by an overloaded site in an overcrowded suburb. The fire set off achain reactions exploding storage tanks. Yet, by a miracle, the two largest tanks did not explode.Had these caught fire, then 3,000 strong rescue team and fire fighters would all have died.From the discussion among some experts we may conclude that ____.
A. to avoid any accidents we should not repair the facilities in chemical industry
B. the local authorities should not be concerned with the production of the chemical industry
C. all these accidents could have been avoided or controlled if effective measure had been taken
D. natural gas stored in very large tanks is always safe
