Consult <br /> an industrial hygienist or similar professional,or your local agencies,for further information. <br /> Engineering Controls: If current ventilation practices are not adequate to maintain airborne dust <br /> concentrations below the established exposure limits (see Section 2), additional ventilation or exhaust <br /> systems may be required. <br /> Personal Protective Equipment <br /> Eye/Face Protection: The use of eye protection (such as goggles) that meets or exceeds ANSI 2.871 is <br /> recommended if dust is generated. Depending on conditions of use a face shield may be necessary. <br /> Skin/Hand Protection: If dust is generated, handle with gloves. Gloves must be inspected prior to use. Use <br /> proper glove removal technique (without touching glove's outer surface)to avoid skin contact with this <br /> product. Dispose of contaminated gloves after use in accordance with applicable laws and good laboratory <br /> practices. Wash and dry hands. <br /> Respiratory: A NIOSH/MSHA approved air purifying respirator with a type N100 particulate filter may be <br /> used under conditions where airborne concentrations are expected to exceed exposure limits (see below). <br /> Protection provided by air-purifying respirators is limited (see manufacturer's respirator selection guide). <br /> Use a positive pressure air supplied respirator if there is potential for uncontrolled release, exposure levels <br /> are not known, or any other circumstances where air-purifying respirators may not provide adequate <br /> protection. A respiratory protection program that meets OSHA's 29 CFR1910.134 and ANSI Z88.2 <br /> requirements must be followed whenever workplace conditions warrant a respirator's use. <br /> Other Protective Equipment: Eye wash and quick-drench shower facilities should be available in the work <br /> area. Thoroughly clean shoes and wash contaminated clothing before reuse. It is recommended that <br /> impervious clothing be worn. <br /> i <br /> i <br /> Page 4 of 9 <br />
