Abstract
A review is undertaken of the hazards to health likely to occur from exposure to gases and fumes generated during various welding processes. Available statistical information about the health of welders, including morbidity and mortality figures, suggests a slightly higher incidence than normal of acute respiratory illness. The present position in regards to welders siderosis is that it is still considered to be a benign condition, although certain recent studies suggest that vigilance cannot be relaxed, particularly as welding conditions are changing. Welding technology is advancing fast and many new methods are appearing; thus, metals and alloys are being welded which could not be by the old established techniques. Consequently, new risks are likely to arise, and they should.be foreseen and dealt with before harm occurs. The solution to most of the gas and fume problems in welding is the provision and use of efficient ventilation devices. The institution of preventive measures should be associated with precise measurement of the environmental risk together with careful assessment of the human effects from the risk.
