Warninq:
The Repair Parts list designates parts that contain refractory ceramic fibers
(RCF). RCF has been classified as a possible human carcinogen. When
exposed to temperatures about 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 Breathinq 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 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.
