 Safety comes first is the motto of Brian Tufnell, a do-it-yourself man. He is in possession of a silver award from the Association of Accident Prevention and as an Associate Fellow of Outstanding Safety he knows the risks involved with home improvements. Therefore he takes every possible precaution to ensure he will live to see tomorrow. He puts on a safety suit and checks every tool carefully. Just in case he might inhale harmful substances or damage his hearing, he puts on a gas mask and hearing protection. Now he is ready for work. But sometimes even the greatest precautions are not enough.
