Formula: Mg(Al₀_.₅_-₁ Fe₀_-₀_.₅)Si₄O₁₀(OH). 4H₂O

Density: 2.2 g/cm³

EXPOSURE & HEALTH EFFECTS
Routes of exposure The substance can be absorbed into the body by inhalation. Effects of short-term exposure	Inhalation risk Evaporation at 20°C is negligible; a harmful concentration of airborne particles can, however, be reached quickly when dispersed. Effects of long-term or repeated exposure Repeated or prolonged inhalation of fibres may cause effects on the lungs. This may result in fibrosis. This substance is possibly carcinogenic to humans.

EXPOSURE & HEALTH EFFECTS

Routes of exposure
The substance can be absorbed into the body by inhalation.

Effects of short-term exposure

Inhalation risk
Evaporation at 20°C is negligible; a harmful concentration of airborne particles can, however, be reached quickly when dispersed.

Effects of long-term or repeated exposure
Repeated or prolonged inhalation of fibres may cause effects on the lungs. This may result in fibrosis. This substance is possibly carcinogenic to humans.

OCCUPATIONAL EXPOSURE LIMITS

ENVIRONMENT

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.
