Summary: Ceramic fibers used in manufacturing this product are
under investigation as a possible animal carcinogen. Two categories of
studies on laboratory animals, breathing high concentrations and artificial
exposure (implantation), have reported tumors. No data from human epidemio-logical
studies are available. Based on animal studies the International Association
for Research on Cancer (IARC) has classified ceramic fibers as a group
2B substance, possibly arcinogenic to humans. This product as sold will
not spontaneously generate any significant emissions of ceramic fiber dust.
After this product has been in service at high temperatures (> 1000°
C), ceramic fibers can transform into crystalline silica. The IARC has
placed crystalline silica in group 1, carcinogenic to humans. Medical conditions
which may be aggravated: Pre-existing upper respiratory and lung diseases
may be aggravated by dust.
Target Organs: Skin, eyes, lungs.
Acute Health Effects: Mechanical irritation of respiratory system, skin, and eyes.
Chronic Health Effects: Exposure to "after service" dust containing cristobalite may cause lung damage such as silicosis.
Primary Entry Route(s): Inhalation, eye and skin contact.
Inhalation: Overexposure to dust may cause irritation or soreness
in the throat and nose.
Skin Contact: Irritation or rash.
Eyes: Irritation or inflammation of the eyes.
Ingestion: May cause irritation to the gastro-intestinal tract.
Inhalation: Remove to fresh air. Drink water to clear throat.
Blow nose to evacuate fibers.
Skin Contact: Wash with soap and water.
Ingestion: Do not induce vomiting.
Eyes: Flush with clean water for 15 minutes.
CONSULT A PHYSICIAN IF ANY SYMPTOMS PERSIST.
Chemical Incompatibilities: Hydrofluoric acid and strong alkalis.
Conditions to Avoid: None in designed use.
Hazardous Decomposition Products: See Section II
HMIS rating: Health = 1 Flammability =1 Reactivity = 0 Personal
Protection = E
Goggles: If processing or handling this material creates excessive dust, goggles and face shield are recommended.
Gloves: Use barrier gloves if handling produces skin irritation.
