Handling ceramic fiber and fiberglass materials
HANDLING OR REMOVAL OF COMBUSTION CHAMBER
The combustion chamber in this product contains ceramic fiber materials.
Ceramic fiber can be converted to cristobalite in very high temperature
applications. The International Agency for Research on Cancer (IARC) has
concluded, “Crystalline silica inhaled in the form of quartz or cristobalite from
occupational sources is carcinogenic to humans (Group 1)”.
WARNING
„
Avoid breathing dust and contact with skin and eyes.
• Use NIOSH certified dust respirator (N95). This type of respirator is based on the OSHA
requirements for cristobalite at the time this document was written. Other types of respirators
may be needed depending on the job site conditions. Current NIOSH recommendations can
be found on the NIOSH web site at
http://www.cdc.gov/niosh/homepage.html . NIOSH
approved respirators, manufacturers, and phone numbers are also listed on this web site.
