Control Technology for Crystalline Silica Exposures in Construction: Wet Abrasive211 Blasting at the Nokia Building Construction Site, Irving, Texas. In-Depth Study 211 Report

摘要

The survey at this site was conducted as part of a larger effort to evaluate the211u001etechnical feasibility of controlling worker exposure to respirable crystalline 211u001esilica. The workers' exposure to dust and crystalline silica was measured. Video 211u001eexposure monitoring was conducted to evaluate the extent to which work practices 211u001econtributed to exposures.
