Abstract
Data on dust control and occupational exposure to silica (7631869) in the United Kingdom were examined. Specific topics addressed included: developments in legislation; the incidence of exposure to silica; distribution of exposure data; airborne dust concentrations; and control measures such as extract ventilation, engineering modifications, overall management health and safety structure, line management supervision, the provision of adequate training in the use of control measures, and a good system of preventive maintenance. For respirable dust, the proportion of samples exceeding the 5mg/m3 limit was in the range of five to 10% for all industries. The higher dust concentrations occurred in the foundry industry, largely at fettling processes. The author concludes that the personal sampling data indicate that effective control of airborne dust for many processes can be achieved and that current United Kingdom occupational exposure limits can be reached. Some problems remain difficult to solve however, and in these cases respiratory protective equipment can be used to supplement engineering control measures.
