Handling ceramic fiber and fiberglass materials

REMOVAL OF COMBUSTION CHAMBER
LINING OR BASE PANELS
The combustion chamber lining or base insu-
lation panels in this product contain ceramic
fiber materials that have been identified as car-
cinogenic, 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 concluded, "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 conditions. Current NIOSH recom-
mendations can be found on the NIOSH web
site at http://www.cdc.gov/niosh/homepage.
html. NIOSH approved respirators, manufac-
turers, 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 insula-
tion from the boiler and place it in a plastic bag for
disposal.
❏ Wash potentially contaminated clothes separately
from other clothing. Rinse clothes washer thor-
oughly.
NIOSH stated First Aid
❏ Eye: Irrigate immediately
❏ Breathing: Fresh air

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.
Precautionary measures
❏ Avoid breathing fiberglass dust and contact with
skin or eyes.
• Use NIOSH certified dust respirator
(N95). This type of respirator is based

• Wear long-sleeved, loose fitting clothing,
gloves, and eye protection.
❏ Operations such as sawing, blowing, tear out, and
spraying may generate airborne fiber concentra-
tion requiring additional protection.
❏ Wash potentially contaminated clothes separately
from other clothing. Rinse clothes washer thor-
oughly.
