FIRE

In case of fire in the surroundings: use appropriate extinguishing media.
EXPLOSION


EXPOSURE
PREVENT DISPERSION OF DUST! AVOID ALL CONTACT!

 •INHALATION Cough.
Local exhaust or breathing protection.

 •SKIN
Protective gloves.
Rinse skin with plenty of water or shower.
 •EYES
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 take to a doctor.
 •INGESTION
Do not eat, drink, or smoke during work.

SPILLAGE DISPOSAL STORAGE PACKAGING & LABELLING
Sweep spilled substance into sealable containers; if appropriate, moisten first to prevent dusting. Personal protection: P2 filter respirator for harmful particles.

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 20C 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:
Lungs may be affected by repeated or prolonged exposure to fibres , resulting in fibrosis. This substance is possibly carcinogenic to humans.

PROPERTIES
Density: 2.2 g/cm
ENVIRONMENTAL
DATA

N O T E S
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. See sections Occupational Exposure Limits, EU classification, Emergency Response.
