Warning:   

The Parts list designates parts that contain refractory ceramic fibers (RCF).    
RFC has been classified as a possible human carcinogen.  When exposed to 
temperatures about 1805°F, such as during direct flame contact, RFC 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 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:
