Handling ceramic fiber and fiberglass materials

REMOVAL OF COMBUSTION CHAMBER
LINING OR BASE PANELS
The combustion chamber lining or base insula-
tion panels in this product contain ceramic fiber
materials that have been identified as carcinogenic,
or possibly carcinogenic, to humans. Ceramic
fibers can be converted to cristobalite in very
high temperature applications. The International
Agency for Research on Cancer (IARC) has con-
cluded, "Crystalline silica inhaled in the form of
quartz or cristobalite from occupational sources
is carcinogenic to humans (Group 1).":
Precautionary measures
❏ 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 condi-
tions. 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.
