Hazards and Protection.
Keep in a cool, dry, dark location in a tightly sealed container or cylinder. Keep away from incompatible materials, ignition sources and untrained individuals. Secure and label area. Protect containers/cylinders from physical damage.
All chemicals should be considered hazardous. Avoid direct physical contact. Use appropriate, approved safety equipment. Untrained individuals should not handle this chemical or its container. Handling should occur in a chemical fume hood.
Wear appropriate clothing to prevent any reasonable probability of skin contact. Wear eye protection to prevent any possibility of eye contact.
At concentrations above the NIOSH rel, or where there is no rel, at any detectable concentration: respirator class(es): any self-contained breathing apparatus that has a full facepiece and is operated in a pressure-demand or other positive pressure-mode. Any supplied-air respirator that has a full facepiece and is operated in a pressure-demand or other positive-pressure mode in combination with an auxiliary self-contained breathing apparatus operated in pressure-demand or other positive-pressure mode.
Keep material out of water sources and sewers. Land spill: Cover solids with a plastic sheet to prevent dissolving in rain or fire fighting water. Dike surface flow using soil, sand bags, foamed polyurethane, or foamed concrete. Water spill: Use natural deep water pockets, excavated lagoons, or sand bag barriers to trap material at bottom. Remove trapped material with suction hoses.
Organic acids have a tendency to react slowly with chrysotile. Because the outer surface of a chrysotile fiber is essentially composed of magnesium hydroxide (brucite), chrysotile is highly susceptible to acid attack.
It is almost completely destroyed within 1 hour in 1 N hydrochloric acid at 95 C.
Extinguish fire using agent suitable for type of surrounding fire. (Material itself does not burn or burns with difficulty.) Keep run-off water out of sewers and water sources.
May burn but does not ignite readily.
Some may burn but none ignite readily. May polymerize explosively when heated or involved in a fire. Containers may explode when heated. Some may be transported hot.
Fire may produce irritating, corrosive and/or toxic gases.
TLV: 2 fibres/cc (as TWA) A1 ppm; mg/m3 (ACGIH 1992-1993). MAK: class III A1 (1993).

Asbestosis - is defined as a diffuse bilateral interstitial fibrosis primarily affecting the lower 2/3 of the lung. Signs and symptoms include breathlessness on effort, finger clubbing, clicking, and rales.
Benign nodules called asbestos corns develop around implanted fibers.
Seek medical assistance.
Move victim to fresh air. Apply artificial respiration if victim is not breathing. Administer oxygen if breathing is difficult.
Remove and isolate contaminated clothing and shoes. Immediately flush with running water for at least 20 minutes.
