TYPES OF HAZARD
/ EXPOSURE 		ACUTE HAZARDS / SYMPTOMS PREVENTION FIRST AID / FIRE-FIGHTING
FIRE Not combustible.    In case of fire in the surroundings, use appropriate extinguishing media. 
EXPLOSION      
 
EXPOSURE   PREVENT DISPERSION OF DUST! AVOID ALL CONTACT!   
Inhalation Cough.  Use breathing protection. Use closed system and ventilation.  Fresh air, rest. 
Skin   Protective gloves. Protective clothing.  Remove contaminated clothes. Rinse skin with plenty of water or shower. 
Eyes   Wear safety goggles 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.

Chemical dangers
 

Occupational exposure limits
TLV ((For fibres longer than 5 µm with an aspect ratio equal to or greater than: 3:1 as determined by the membrane filter method at 400-450X magnification (4-mm objective) phase-contrast illumination) ): 0.1f/cc as TWA; A1 (confirmed human carcinogen); (ACGIH 2004).
MAK: Carcinogen category: 1; (DFG 2004).
EU OEL ( selected):.
EU OEL ( selected): 0.1fibres/ml as TWA;. 

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

Inhalation risk
A harmful concentration of airborne particles can be reached quickly when dispersed. 

Effects of short-term exposure
 

Effects of long-term or repeated exposure
Repeated or prolonged inhalation may cause asbestosis (fibrosis of the lungs), pleural plaques, thickening and effusions. This substance is carcinogenic to humans. This substance causes cancer of the lung, mesothelioma, cancer of the larynx, and cancer of the ovary in humans. There is limited evidence that this substance causes colorectal cancer or cancer of the pharynx or stomach. 


PHYSICAL PROPERTIES ENVIRONMENTAL DATA
Melting point: No 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.
