Based on its review, IARC classified crystalline silica as a group 2A carcinogen (probable human carcinogen). The OSHA permissible exposure limit (PEL for cristobalite is 0.05 mg/m3 (respirable dust). The ACGIH threshold limit value (TLV) for cristobalite is 0.05 mg/m3 (respirable dust) (ACGIH 1991-92). Use NIOSH or MSHA approved equipment when airborne exposure limits may be exceeded. The minimum respiratory protection recommended for given airborne fiber or cristobalite concentrations are: CONCENTRATION 0-1 fiber/cc or 0-0.05 mg/m3 cristobalite Optional disposable dust respirator (e.g. 3M 9970 (the OSHA PEL) or equivalent). Up to 5 fibers/cc or up to 10 times the Half face, air-purifying respirator equipped with high OSHA PEL for cristobalite efficiency particulate air (HEPA) filter cartridges (e.g. 3M 6000 series with 2040 filter or equivalent). Up to 25 fibers/cc or 50 times the OSHA Full face, air-purifying respirator with high efficiency PEL for cristobalite (2.5 mg/m3) particulate air (HEPA) filter cartridges (e.g. 3M 7800S with 7255 filters or equivalent) or powered air -purifying respirator (PARR) equipped with HEPA filter cartridges (e.g. 3M W3265S with W3267 filters or equivalent). Greater than 25 fibers/cc or 50 times the Full face, positive pressure supplied air respirator OSHA PEL for cristobalite (2.5 mg/m3) (e.g. 3M 7800S with W9435 hose & W3196 low pressure regulator kit connected to clean air supply or equivalent). If airborne fiber or cristobalite concentrations are not known, as minimum protection, use NIOSH/MSHA approved half face, air-purifying respirator with HEPA filter cartridges. Rosemount Analytical Inc. A Division of Emerson Process Management Instruction Manual IB-106-340 Rev. 3.0 Oxymitter 4000 December 2003 Insulation surface should be lightly sprayed with water before removal to suppress airborne dust. As water evaporates during removal, additional water should be sprayed on surfaces as needed. Only enough water should be sprayed to suppress dust so that water does not run onto the floor of the work area. To aid the wetting process, a surfactant can be used. After RCF removal is completed, dust-suppressing cleaning methods, such as wet sweeping or vacuuming, should be used to clean the work area. If dry vacuuming is used, the vacuum must be equipped with HEPA filter. Air blowing or dry sweeping should not be used. Dust-suppressing components can be used to clean up light dust. Product packaging may contain product residue. Do not reuse except to reship or return Ceramic Fiber products to the factory. Rosemount Analytical Inc.
