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   AVOID ALL CONTACT!   
Inhalation Cough. Sore throat.  Use local exhaust or breathing protection. Avoid inhalation of dust.  Fresh air, rest. 
Skin Redness. Itching.  Protective gloves. Protective clothing.  Rinse and then wash skin with water and soap. 
Eyes Redness. Pain.  Wear safety goggles.  Rinse with plenty of water for several minutes (remove contact lenses if easily possible). 
Ingestion No acute symptoms expected.  Do not eat, drink, or smoke during work.  Rinse mouth. 

SPILLAGE DISPOSAL
PACKAGING & LABELLING
Personal protection: particulate filter respirator adapted to the airborne concentration of the substance. Vacuum with specialist equipment (See Notes) or carefully sweep into sealable containers. If appropriate, moisten first to prevent dusting. Then store and dispose of according to local regulations.

Physical dangers
 

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) ): 0.2f/cc as TWA; A2 (suspected human carcinogen); (ACGIH 2012).
MAK: Carcinogen category: 2; (DFG 2011); under study.
EU OEL: SCOEL recommendation available. 

Routes of exposure
Exposure mainly occurs via inhalation. 

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

Effects of short-term exposure
May cause mechanical irritation to the respiratory tract, eyes and skin. 

Effects of long-term or repeated exposure
Lungs may be affected by repeated or prolongated exposure. This substance is possibly carcinogenic to humans. See Notes. 


PHYSICAL PROPERTIES ENVIRONMENTAL DATA
Melting point: 1700-2040°C
Density: 2.6-2.7 g/cm³
Solubility in water: none 
 

NOTES
Crystalline materials, such as crystalline silica, produced from ceramic fibres when heated over 1000° C present a possibly increased risk of lung cancer to workers.
NEVER use a domestic-type vacuum cleaner to vacuum the substance, only use specialist equipment.
Periodic medical evaluation of exposed workers is recommended.
The European Commission Scientific Committee on Occupational Exposure Limits classified refractory ceramic fibres as carcinogen group C (genotoxic carcinogens for which a practical threshold is supported.)
