WHITE TO GREY FIBRES.

OCCUPATIONAL EXPOSURE LIMITS:
TLV not established.
MAK: Carcinogen category: 2; (DFG 2004).
ROUTES OF EXPOSURE:
The substance can be absorbed into the body by inhalation.

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

EFFECTS OF LONG-TERM OR REPEATED EXPOSURE:
Lungs may be affected by repeated or prolonged exposure to fibres, resulting in fibrosis. This substance is possibly carcinogenic to humans.
PHYSICAL PROPERTIES
Density: 2.2 g/cm
ENVIRONMENTAL DATA

NOTES
Depending on the degree of exposure, periodic medical examination is suggested. Do NOT take working clothes home. Fibre length varies with the source of the mineral. Experimental carcinogenity is associated with respirable fibres greater than 5 micrometers in length.
