• Description:
  When construction workers use handheld grinders to smooth poured concrete surfaces after forms are stripped, they risk overexposure to respirable dust and crystalline silica. This article examines the performance of a local exhaust ventiliation system for handheld grinders. The system consisted of the grinder (equipped with a ventilated shroud), a length of flexible corrugated hose, and a portable electric vacuum cleaner that acted as the fan and dust collector for the ventilation system (see Figures 1 and 2). Personal breathing zone air samples for respirable dust and crystalline silica were collected during five days of grinding. [Description provided by NIOSH]
