  • Description:
    "A study was undertaken of the working conditions for those employed in the business of abrasive blasting. The facilities studied were located in Texas, Alabama, Pennsylvania, New Jersey, Maine, Washington, and Kansas. Participating workers completed an abrasive blaster respiratory protection survey designed to determine the degree of respiratory protection currently afforded them during their blasting tasks. The returns indicated over 72,000 manhours per month were performed by 1018 workers in 160 reporting establishments. The number of blasters employed by a single firm varied from 1 to 120. Samples of airborne particle sizes taken from the breathing zone of the various workers indicated in all cases particles which were well within the respirable range. The findings of this study suggest there were as many as 100,000 abrasive blasters with personal exposures to silica (14808607) dust environments up to 60 million manhours per year. The protection given to the workers was at best marginal and ranged to poor. In most cases there were deficiencies in equipment and lack of proper maintenance. Threshold limit values for quartz exposure and noise exposure were exceeded in most locations." - NIOSHTIC-2
