CALCIUM CHLORIDE <br />Page 4 of 7 <br />A system of local and/or general exhaust is recommended to keep employee exposures as <br />low as possible. Local exhaust ventilation is generally preferred because it can control the <br />emissions of the contaminant at its source, preventing dispersion of it into the general work <br />area. Please refer to the ACGIH document, Industrial Ventilation, A Manual q f' <br />Recommended Practices, most recent edition, for details. <br />Personal Respirators (NIOSH Approved): <br />For conditions of use where exposure to dust or mist is apparent and engineering controls <br />are not feasible, a particulate respirator (NIOSH type N95 or better filters) may be worn. If <br />oil particles (e.g. lubricants, cutting fluids, glycerine, etc.) are present, use a NIOSH type R <br />or P filter. For emergencies or instances where the exposure levels are not known, use a <br />full-face positive-pressure, air-supplied respirator. WARNING: Air-purifying respirators do <br />not protect workers in oxygen-deficient atmospheres. <br />Skin Protection: <br />Wear protective gloves and clean body-covering clothing. <br />Eye Protection: <br />Use chemical safety goggles and/or full face shield where dusting or splashing of solutions <br />is possible. Maintain eye wash fountain and quick-drench facilities in work area. <br />Other Control Measures: <br />Maintain good housekeeping in work area. Dust deposits on floors and other surfaces may <br />pick up moisture and cause the surfaces to become slippery and present safety hazards. <br />9.
