Handling ceramic fiber materials
REMOVAL OF COMBUSTION CHAMBER LINING
WARNING
The combustion chamber insulation in this appliance contains ceramic fiber material. Ceramic fibers can be converted to cristobalite in very high temperature applications. The International Agency for Research on Cancer (IARC) has concluded, “Crystalline silica in the form of quartz or cristobalite from occupational sources is carcinogenic to humans (Group 1).” Normal operating temperatures in this appliance are below the level to convert ceramic fibers to cristobalite. Abnormal operating conditions would have to be created to convert the ceramic fibers in this appliance to cristobalite.
The ceramic fiber material used in this appliance is an irritant; when handling or replacing the ceramic materials it is advisable that the installer follow these safety guidelines.
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 website at http://www.cdc.gov/niosh/
homepage.html. NIOSH approved respirators, manufacturers, and phone numbers are also listed on this website.
•Wear
Apply enough water to the combustion chamber lining to prevent airborne dust.
Remove the combustion chamber lining from the appliance and place it in a plastic bag for disposal.
Wash potentially contaminated clothes separately from other clothing. Rinse clothes washer thoroughly.
