XI. SPECIAL PRECAUTIONS / SUPPLEMENTAL INFORMATION
Product which has been in service at elevated temperatures (greater than 1800
°F) may undergo partial conversion to cristobalite, a form of crystalline silica.
Chronic exposure to respirable crystalline silica may lead to delayed lung injury
(silicosis). The amount of cristobalite present will depend on the temperature and
length in service.
IARC has concluded that crystalline silica from occupational sources inhaled in the
form of quartz or cristobalite is carcinogenic to humans (Group 1)
[IARCMonograph Vol. 68, June 1997]. The OSHA permissible exposure limit
(PEL) and the 1988-89 ACGIH threshold limit value (TLV) for cristobalite is 0.05
mg/if (respirable dust). Particular care should be taken when working with “used”
material to minimize generation of dust. When removing and handling product
used in high temperature applications, special caution should be taken.to avoid
unnecessary cutting and tearing of the used material to minimize generation of
airborne dust. Workers should. Use respiratory protection. Use NIOSH or MSHA
approved equipment when airborne exposure limits may be exceeded, especially
in confined areas with inadequate ventilation.
Insulation surfaces should be lightly sprayed with H
2
O 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 on to the fiber in the work area.
After RCF removal is completed, dust-suppressing cleaning methods, such as wet
sweeping or wet vacuuming, should be used to clean the work area. If dry
vacuuming is used, the vacuum must be equipped with a HEPA filter. Air blowing
or dry sweeping should never be used. Dust-suppressing components can be
used to clean up light dust.
