Handling ceramic fiber and fiberglass materials

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).":
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.

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 are also listed on this web site.
• 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.
