摘要

Safety procedures are vital on petrol station forecourts, where even the slightest spark could result in a major conflagration. David Bonnett describes the precautions which should betaken. Petrol is an extremely flammable liquid. It gives off a highly toxic vapour that does not disperse easily. This can create a flammable atmosphere when as little as 1% is mixed with air. This means that petrol stations are potentially very dangerous places.
