[Explosion accidents during work with tires and wheel rims]

The object of this work is to draw attention to injuries resulting from explosions caused by work with wheel rims and tyres, the extent of the problem and the safety rules which already exist. Seven illustrative cases are presented. A not inconsiderable but frequently disregarded risk for accidental explosions is present in connection with pumping tyres and repairs of tyres and wheel rims. During the explosions, pressure waves of enormous violence may frequently be released. In connection with four accidental explosions of this type, a total of seven persons were injured. Four of these sustained life-threatening injuries. On the basis of the serious accidents, the authors consider it important to draw attention to the fact that the rules, which exist already and which are aimed primarily at avoiding and possibly limiting the extent of the violent explosive energy, should be brought to the notice of all who work with tyres and wheel rims.
