TYPES OF
HAZARD /
EXPOSURE
ACUTE HAZARDS / SYMPTOMS      PREVENTION      FIRST AID / FIRE FIGHTING
FIRE     In case of fire in the surroundings, use appropriate extinguishing media. 
EXPLOSION      
 
EXPOSURE   PREVENT DISPERSION OF DUST! AVOID ALL CONTACT!   
Inhalation Cough.  Use local exhaust or breathing protection.   
Skin   Protective gloves.  Rinse skin with plenty of water or shower. 
Eyes   Wear safety spectacles or eye protection in combination with breathing protection if powder.  First rinse with plenty of water for several minutes (remove contact lenses if easily possible), then refer for medical attention. 
Ingestion   Do not eat, drink, or smoke during work.   

SPILLAGE DISPOSAL
PACKAGING & LABELLING
Personal protection: particulate filter respirator adapted to the airborne concentration of the substance. Sweep spilled substance into covered sealable containers. If appropriate, moisten first to prevent dusting.

IMPORTANT DATA
Physical State; Appearance
WHITE-TO-GREY FIBRES. 

Physical dangers
 

Chemical dangers
 

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

Effects of short-term exposure
 

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. 


PHYSICAL PROPERTIES ENVIRONMENTAL DATA
Density: 2.2 g/cm³   

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.
Card has been partly updated in April 2005.
