Occupational Health in Metal Arc Welding

Abstract

The physical and often acute effects associated with metal arc welding, such as death by electrocution or physical injuries in the workplace are well recog nised. Increasingly today, attention is focused upon chronic effects, in particu lar cancer risks in welders. This review aims to address these concerns; put the risks into perspective and direct the reader to the means of assessment and control. Attention is drawn to the activities of Commission VIII International Institute of Welding which, through its various working groups, is charged with reviewing world-wide publications on health and safety in welding and with the issue of authoritative statements. The mechanism of gas and fume generation from welding processes is described. Fume particle size and mor phology in relation to inhalation and effects within the body are addressed. Epidemiology studies on cancer and other risks are reviewed. Strategies for the assessment and control of risks from metal arc welding are considered, taking due note of international movements on legislation and standardisation.
