Handling ceramic fiber and fiberglass materials
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. 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).":
Suppliers of fiberglass wool products recommend the
following precautions be taken when handling these
materials:
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

To avoid personal injury, death or property
damage, keep the boiler area clear and free
from combustible materials, gasoline and
other flammable vapors and liquids.
Do not block flow of air to boiler.
Incomplete combustion and carbon
monoxide emissions can cause severe
personal injury, death or substantial
property damage.
Do not store sources of hydrocarbons (i.e.,
bleaches, cleaners, chemicals, sprays, paint
removers, fabric softeners, etc.) in boiler
area. This can contribute to shortened
boiler/vent system life.
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.
• Operations such as sawing, blowing, tear out and spraying
may generate airborne fiber
ditional protection. 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.
