Part Number 550-110-738/1012
Handling ceramic fiber and fiberglass materials
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).”:
Precautionary measures
n
Avoid breathing fiberglass dust and contact with skin or 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 are also listed on this web site.
•
Wear long‑sleeved, loose fitting clothing, gloves, and eye protection.
n
Apply enough water to the combustion chamber lining or base insulation to prevent airborne dust.
n
Remove combustion chamber lining or base insulation from the boiler and place it in a plastic bag for
disposal.
n
Wash potentially contaminated clothes separately from other clothing. Rinse clothes washer thoroughly.
NIOSH stated First Aid.
n
Eye: Irrigate immediately
n
Breathing: Fresh air.
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.
