摘要

When construction workers use hand-held grinders to smooth poured concrete surfaces after forms are stripped, they risk overexposure to respirable dust and crystalline silica. This report examines the performance of a local exhaust ventilation system for hand-held grinders. The system consisted of the grinder, which was equipped with a ventilated shroud, and length of flexible corrugated hose, and a portable electric vacuum cleaner that acted as the fan and dust collector for the ventilation system. Air samples for respirable dust and crystalline silica were collected during five days of grinding. The results of air sampling indicate that this vacuum cleaner and shroud system control exposures within the range of protection provided by a half-mask respirator.
