Important Product Safety Information
Refractory Ceramic Fiber Product
WARNING
The Service Parts list designates parts that 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, 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 work involving RCF without
wearing the following protective gear:
1. A National Institute for Occupational Safety and Health (NIOSH) approved
respirator
2. Long sleeved, loose fitting clothing
3. Gloves
4. Eye Protection
• 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.
