V. HEALTH HAZARDS

A. Summary/Risks

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.

B. Signs/Symptoms of Overexposure

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.

C. First Aid/Emergency Procedures

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.
 
VI. REACTIVITY DATA

Chemical Incompatibilities: Hydrofluoric acid and strong alkalis.
Conditions to Avoid: None in designed use.
Hazardous Decomposition Products: See Section II
 
VII. SPILL OR LEAK PROCEDURES
 
Procedures for Spill/Leak: Vacuum dust and debris with a cleaner equipped with a HEPA filter.
Waste Management: This product is not listed as a hazardous waste nor does it exhibit any
characteristics of a hazardous waste.
 
VIII. SPECIAL PROTECTION INFORMATION

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.

Respiratory:
LYTHERM AS SOLD:
Less than 0.5 fiber/cc, use 3M 9900 or equivalent.
< 10 fibers/cc, use MSA COMFO Half-Mask (or equivalent) with HEPA filters.
< 50 fibers/cc, use MSA ULTRA-TWIN (or equivalent) with HEPA filters.
> 50 fibers/cc, use NIOSH approved full face respirator with positive-pressure supplied air.
AFTER SERVICE AT TEMPS. > 1800° F:
< 0.25 mg/cu. m, use MSA COMFO Half-Mask (or equivalent) with HEPA filters.
< 1.25 mg/cu. m, use MSA ULTRA-TWIN (or equivalent) with HEPA filters.
> 1.25 mg/cu. m, use NIOSH approved full face respirator with positive-pressure air supply.

Ventilation: Ventilate to minimize airborne fibers.
Other: Wash hands after handling. Wash contaminated clothing separately. Disposable coveralls are recommended if excessive dusting occurs.
 
IX. SPECIAL PRECAUTIONS

Special Handling/Storage: Keep this material dry.
Special Workplace Engineering Controls: Ventilate to minimize airborne dust.
