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 Inter-
national 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 de-
pending 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 res-
pirators, 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 in-
sulation 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
REMOVAL OF FIBERGLASS WOOL
or
INSTALLATION OF FIBERGLASS WOOL
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
on the OSHA requirements for fiberglass
wool at the time this document was writ-
ten. 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, manufactur-
ers, 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 concentra-
tion requiring additional protection.
❏ Wash potentially contaminated clothes separately
from other clothing. Rinse clothes washer thor-
oughly.
