IARC has recently reviewed the animal, human, and other relevant
experimental data on silica in order to critically evaluate and classify the
cancer causing potential. 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
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.
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.
