CHRYSOTILE

ICSC: 0014

IMPORTANT DATA

PHYSICAL STATE; APPEARANCE:
WHITE, GREY, GREEN OR YELLOWISH FIBROUS SOLID.

OCCUPATIONAL EXPOSURE LIMITS:
TLV: (For fibres longer than 5 um with an aspect ratio equal to or greater than: 3:1 as determined by the membrane filter method at 400-450X magnefication (4-mm objective) phase contrast elimination) 0.1 fibre/cc as TWA; A1 (confirmed human carcinogen); (ACGIH 2004).
MAK: Carcinogen category: 1; (DFG 2004).
EU OEL: 0.1 fibres/cc (EU 2003).

ROUTES OF EXPOSURE:
The substance can be absorbed into the body by inhalation.

INHALATION RISK:
Evaporation at 20°C is negligible; a harmful concentration of airborne particles can, however, be reached quickly.

EFFECTS OF LONG-TERM OR REPEATED EXPOSURE:
The substance may have effects on the lungs, resulting in pulmonary fibrosis and mesothelioma. This substance is carcinogenic to humans.

PHYSICAL PROPERTIES

Melting point (decomposes): see Notes
Density: 2.2-2.6 g/cmł
Solubility in water: none

ENVIRONMENTAL DATA

NOTES

The substance is heat resistant up to 500°C and completely decomposed at temperatures of 1000°C. Depending on the degree of exposure, periodic medical examination is indicated. Do NOT take working clothes home. The recommendations on this Card also apply to other forms of asbestos.
