| Abstract |
A report produced under contract for the National Institute for Occupational Safety and Health. A postal survey of the degree of respiratory protection provided for workers in abrasive blasting operations in 3,903 firms (masonry, foundries, etc.) in specific areas of 5 States of the USA is described, and the results obtained are indicated. A representative sample of these firms was selected for on-site survey and monitoring. This on-site survey comprised an interview, the determination of the nature and concentration of dusts to which abrasive blasters were exposed and also noise level measurements. The results showed that typical operations are dry-blast by hand-held hose using silica sand on steel or stone in an open area with limited respiratory protection. Approximately 70% of the work resulted in silica dust generation. A wide range of protective equipment was used and the degree of protection provided by each individual type varied considerably; little effort was made to ensure good fit; blasting helmets were found to be poorly designed. No effective supervision of the use of protective equipment was found. Recommendations on improved equipment and practices are given. |
