Assessing Worker Exposures During Abrasive Blasting: Industrial Hygiene Field Guidance for Bioenvironmental Engineers.
Abstract
In the past, it has been difficult to measure worker exposures during abrasive blasting operations. Accepted sampling methods for metals, such as filters in cassettes, results in rapid overloading and shredding of the filter by high-velocity particles projected into the inlet after rebound from the surface being blasted. In addition, non-inhalable particles larger than 100 micrometers are abundant during abrasive blasting and are easily captured by these sampling methods. Analysis of this non-inhalable dust can result in a considerable overestimation of worker exposures to airborne metals. As a result of these concerns, the Industrial Hygiene Branch of the Air Force Institute for Environment, Safety and Occupational Health Risk Analysis (AFIERA) recently completed an Air Force-wide assessment of worker exposures during abrasive blasting operations. The study design, data analysis, and sampler development were accomplished in collaboration with researchers from the University of Cincinnati. This technical report summarizes our recommended sampling methodology, data interpretation, ventilation requirements, personal protective equipment, and workplace practices for abrasive blasting.
