Handling ceramic fi ber
and fi berglass materials
The
200i
boiler contains some ceramic
fi ber and fi berglass materials. Ceramic
fi ber materials, such as the burner gas-
ket, may contain carcinogenic particles
(chrystobalites) after exposure to heat.
Airborne particles from fi berglass or
ceramic fi ber components have been
listed as potentially carcinogenic by the
State of California. Take the following
precautions when removing, replacing
and handling these items.
Protective measures
Avoid breathing dust and avoid contact with skin
or eyes. Wear long-sleeved, loose-fi tt ing cloth-
ing, gloves and eye protection. Use a NIOSH
N95 certifi ed respirator. Th is respirator meets
requirements for protection from chrystobalites.
Th e actual job requirements or NIOSH regula-
tions may require other or additional protection.
For information, refer to the NIOSH website,
htt p://www.cdc.gov/niosh/homepage.html.
Ceramic fi ber removal
Ceramic fi ber removal: To prevent airborne dust,
thoroughly wet ceramic fi ber with water before
handling. Place ceramic fi ber materials in a plastic
bag and seal to dispose.
Avoid blowing, tearing, sawing or spraying fi ber-
glass or ceramic fi ber materials. If such operations
are necessary, wear extra protection to prevent
breathing dust.
Wash work clothes separately from other laundry.
Rinse clothes washer thoroughly aft erwards to pre-
vent contamination of other clothing.
NIOSH First aid procedures:
Eye exposure — irrigate immediately
Breathing — fresh air.
