Important Product Safety Information:
Refractory Ceramic Fiber Product
WARNING
Some boiler components contain refractory ceramic fibers (RCF). RCF has
been classified as a possible human carcinogen. When exposed to
temperatures above 1805°F, such as during direct flame contact, RCF
changes into crystalline silica, a known carcinogen. When disturbed as a
result of servicing or repair, these substances become airborne and, if
inhaled, may be hazardous to your health.
AVOID BREATHING FIBER PARTICULATES AND DUST
Precautionary Measures
:
• Do not remove or replace RCF parts or attempt any service or repair work involving RCF
without wearing the following protective gear:
1. A National Institute for Occupational Safety and Health (NIOSH) approved air-purifying
respirator equipped with 100-series particulate filter, as a minimum
2. Long sleeved, loose fitting clothing
3. Gloves
4. Eye Protection
• Dampen RCF to be removed with light water spray to prevent fibers from becoming
airborne.
• Take steps to assure adequate ventilation.
• Wash all exposed body areas gently with soap and water after contact.
• Wash work clothes separately from other laundry and rinse washing machine after use to
avoid contaminating other clothes.
• Discard used RCF components by sealing in an airtight plastic bag. RCF and crystalline silica
are not classified as hazardous wastes in the United States and Canada.
First Aid Procedures
:
• If contact with eyes: Flush with water for at least 15 minutes. Seek immediate medical
attention if irritation persists.
• If contact with skin: Wash affected area gently with soap and water. Seek immediate
medical attention if irritation persists.
• If breathing difficulty develops: Leave the area and move to a location with clean fresh air.
Seek immediate medical attention if breathing difficulties persist.
• Ingestion: Do not induce vomiting. Drink plenty of water. Seek immediate medical
attention.
