Product or Trade Name....  Amosite asbestos fiber

Emergency Overview:
Amosite asbestos is a known human carcinogen.

Section 2: Composition

         Name            CAS #          EC#             Approximate Weight %
         Amosite         12172-73-5     n/a             >99.99%

Confirmed carcinogen by ACGIH, IARC, OSHA AND NTP.

NFPA (Scale 0-4):
    Not known

Section 3: Hazard Identification

Potential Health Effects:
    Acute: Overexposure to breathing asbestos may cause asbestosis,
    pulmonary fibrosis, mesothelioma, other	lung disorders or cancer.  
    Handling of materials and smoking or eating prior to washing could be 
    hazardous.  Medical examination and x-rays are required to determine
    signs & symptoms of exposure.

Routes of exposure:  Inhalation, Skin contact, Ingestion

Medical Conditions Aggravated by Exposure:
    Pulmonary disease

Occupational Exposure Limits:

TLV: 0.1 fiber/cc (as TWA)
A1 (ACGIH 1998.  For fibers longer than 5µm with an aspect ratio equal to or
greater than 3:1 as determined at 400-450X magnification by the membrane filter

Strong oxidizers, strong acids, and bases

Route of entry: Inhalation, Skin contact, Ingestion
Target organs:  Lungs

There are not acute signs or symptoms associated with asbestos.  Diseases
associated with over exposure are chronic, generally taking from 10 to 40 years
to become apparent.

Section 4: First Aid Measures

Eyes:  In case of contact, immediately flush eyes with copious amounts of
       flowing water for at least 15 minutes, retracting eye lids often.
       Get medical attention immediately.  Contact lenses should not be
       worn when working with this product.

Skin:  Wash skin thoroughly with mild soap and water.  Flush with copious 
       amounts of water for 15 minutes.  

Inhalation: Move the exposed person to fresh air at once.  Support breathing.
            If symptoms persist contact physician.

Ingestion:  Get medical aid immediately.

Section 5: Fire Fighting Measures

Flammability classification:  Not classified. 
	Heat resistant up to 500°C; is completely decomposed at 
	a temperature of 1000°C. 

Flash Point/Method:  Not known

Auto-Ignition Temperature:  Not determined

Flammable Limits:  Lower:  Not applicable
                   Upper:  Not applicable

Extinguishing Media:  Water, Foam, Dry Chemical

Unusual Fire Hazards:  Toxic gases and asbestos particulate may be
	Released in a fire.

Firefighting procedures/instructions:
 	Use NIOSH approved self-contained breathing apparatus and full
	protective equipment.
Properties that could increase fire or explosion hazard:
         Combustibility of this material results from paraffin lubrication.

Section 6: Accidental Release Measures

Use HEPA vacuum wet methods when feasible.  Use appropriate personal
protection for clean-up personnel.

Section 7: Handling and Storage

Storage and handling:
Store in well-sealed container in cool, dry area.

Section 8: Exposure Controls and Personal Protection

ANSI approved eye wash and deluge shower should be available in the work area.

Personal Protective Equipment (PPE):
