Important Product Safety Information

Refractory Ceramic Fiber Product

Warning

:

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 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 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.
