Product or Trade Name.... Chrysotile asbestos fiber
Emergency Overview:
Chrysotile asbestos is a known human carcinogen.
Name CAS # EC# Approximate Weight %
Chrysotile 12001-29-5 650-013-006 >99.99%
Confirmed carcinogen by ACGIH, IARC, OSHA AND NTP.
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
method).
Incompatibilies:
Strong oxidizers, strong acids, and bases
Route of entry: Inhalation, Skin contact, Ingestion
Target organs: Lungs
Symptoms:
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.
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.
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.
Use HEPA vacuum wet methods when feasible. Use appropriate personal protection for clean-up personnel.
Storage and handling: Store in well-sealed container in cool, dry area.
ANSI approved eye wash and deluge shower should be available in the work area. Personal Protective Equipment (PPE): Eye/Face Protection: ANSI 87.1 approved chemical safety glasses with side shield.
