REMOVAL OF COMBUSTION CHAMBER LINING OR BASE PANELS
The combustion chamber lining or base insulation panels in this product contain ceramic fiber materials. Ceramic
fibers 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).":
Handling fiberglass and ceramic fiber materials
■ 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.
• Wear long-sleeved, loose fitting clothing, gloves, and eye protection.
■ Apply enough water to the combustion chamber lining or base insulation to prevent airborne dust.
■ Remove combustion chamber lining or base insulation from the boiler and place it in a plastic bag for disposal.
■ Wash potentially contaminated clothes separately from other clothing. Rinse clothes washer thoroughly.
NIOSH stated First Aid.
■ Eye: Irrigate immediately
■ Breathing: Fresh air.
REMOVAL OF FIBERGLASS WOOL — OR —
INSTALLATION OF FIBERGLASS WOOL, COMBUSTION CHAMBER LINING OR BASE
PANELS:
This product contains fiberglass jacket insulation and ceramic fiber materials in combustion chamber lining or base
panels in gas fired products. Airborne fibers from these materials have been listed by the State of California as a
possible cause of cancer through inhalation.
■ 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
fiberglass wool 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

• Wear long-sleeved, loose fitting clothing, gloves, and eye protection.
■ Operations such as sawing, blowing, tear out, and spraying may generate airborne fiber concentration requiring
additional protection.
■ Wash potentially contaminated clothes separately from other clothing. Rinse clothes washer thoroughly.
NIOSH stated First Aid.
■ Eye: Irrigate immediately
■ Breathing: Fresh air.
