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. Ce-
ramic 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).”:
o
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.
o
Apply enough water to the combustion chamber lining or base insulation to prevent airborne dust.
o
Remove combustion chamber lining or base insulation from the boiler and place it in a plastic bag for disposal.
o
Wash potentially contaminated clothes separately from other clothing. Rinse clothes washer thoroughly.
NIOSH stated First Aid.
o
Eye: Irrigate immediately
o
Breathing: Fresh air.
REMOVAL OF FIBERGLASS WOOL — OR —
INSTALLATION OF FIBERGLASS WOOL, COMBUSTION CHAMBER 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.
o
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.
o
Operations such as sawing, blowing, tear out, and spraying may generate airborne fiber concentration
requiring additional protection.
o
Wash potentially contaminated clothes separately from other clothing. Rinse clothes washer thoroughly.
NIOSH stated First Aid.
o
Eye: Irrigate immediately
o
Breathing: Fresh air.
