WARNING
Product Safety Information
Refractory Ceramic Fiber Product
This appliance contains materials made from
refractory ceramic fibers (RCF). Airborne RCF,
when inhaled, have been classified by the
International Agency for Research on Cancer
(IARC), as a possible carcinogen to humans.
After the RCF materials have been exposed to
temperatures above 1800°F (980°C), they can
change into crystalline silica, which has been
classified by the IARC as carcinogenic to
humans. If particles become airborne during
service or repair, inhalation of these particles
may be hazardous to your health.
Avoid Breathing Fiber Particulates and Dust
Suppliers of RCF recommend the following
precautions be taken when handling these
materials:
Precautionary Measures:
Provide adequate ventilation.
Wear a NIOSH/MSHA approved respirator.
Wear long sleeved, loose fitting clothing and
gloves to prevent skin contact.
Wear eye goggles.
Minimize airborne dust prior to handling and
removal by water misting the material and
avoiding unnecessary disturbance of
materials.
Wash work clothes separately from others.
Rinse washer thoroughly after use.
Discard RCF materials by sealing in an airtight
plastic bag.
First Aid Procedures:
Inhalation: If breathing difficulty or irritation
occurs, move to a location with fresh clean air.
Seek immediate medical attention if symptoms
persist.
Skin Contact: Wash affected area gently with a
mild soap and warm water. Seek immediate
medical attention if irritation persists.
Eye Contact: Flush eyes with water for 15 min-
utes while holding eyelids apart. Do not rub
eyes. Seek immediate medical attention if irrita-
tion persists.
Ingestion: Drink 1 to 2 glasses of water. Do not
induce vomiting. Seek immediate medical
attention.
