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 con- tain 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,“Crystal- line 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 recommen- dations 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 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 thoroughly.

NIOSH stated First Aid.

❏Eye: Irrigate immediately.

❏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 materi- als in combustion chamber lining or base panels in gas fired products. Air- borne 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

•Wear long-sleeved, loose fitting clothing, gloves, and eye protection.

❏Operations such as sawing, blowing, tear out, and spraying may generate airborne fiber concentration requiring additional protection.

❏Wash potentially contaminated clothes separately from other clothing. Rinse clothes washer thoroughly.

NIOSH stated First Aid.

❏Eye: Irrigate immediately.

❏Breathing: Fresh air.
