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	ENVIRONMENTAL DATA
Melting point (decomposes): see Notes Density: 2.2-2.6 g/cm³ Solubility in water: none

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.
