Abrasive Blasting Respiratory Protective Practices Survey.
National Institute for Occupational Safety and Health, Final Report 1973 Aug:122 pages
The degree of respiratory protection currently afforded workers in industries which employ abrasive blasting techniques has been investigated. From a preliminary postal survey of 3903 firms a representative population was chosen for on-site survey and monitoring. The results of this study indicate there are approximately 100,000 abrasive blasters with personnel exposures to silica (7631869) dust environments up to 60,000,000 manhours per year. The protection afforded these workmen is, on the average, marginal to poor. Equipment deficiencies and lack of maintenance are the rule rather than the exception. The average sand blaster would appear to have an excellent chance of receiving above threshold limit values of quartz (1317799) exposures and extreme noise exposures.
