  ACUTE HAZARDS PREVENTION FIRE FIGHTING
FIRE & EXPLOSION Not combustible.        In case of fire in the surroundings, use appropriate extinguishing media.   

   
  SYMPTOMS ACUTE HAZARDS FIRST AID
Inhalation      
Skin   Protective gloves.  Remove contaminated clothes. Rinse skin with plenty of water or shower. 
Eyes Redness. Pain.  Wear safety spectacles.  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.  Rest. Refer for medical attention . 

SPILLAGE DISPOSAL CLASSIFICATION & LABELLING
Personal protection: particulate filter respirator adapted to the airborne concentration of the substance. Sweep spilled substance into covered containers. If appropriate, moisten first to prevent dusting. Carefully collect remainder. Then store and dispose of according to local regulations.

PHYSICAL & CHEMICAL INFORMATION

Physical State; Appearance
BLUE-TO-GREEN POWDER OR BLACK PARTICLES. 

Physical dangers
 

Chemical dangers
Decomposes on heating. This produces chromic oxide. 

Formula: Cr(HO)3.nH2O
Molecular mass: see Notes
Solubility in water: none 


EXPOSURE & HEALTH EFFECTS

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

Effects of short-term exposure
May cause mechanical irritation to the eyes. 

Inhalation risk
Evaporation at 20°C is negligible; a nuisance-causing concentration of airborne particles can, however, be reached quickly , especially if powdered. 

Effects of long-term or repeated exposure
 


Occupational exposure limits
TLV: 0.5 mg/m3, ppm, as TWA; A4 (not classifiable as a human carcinogen).
MAK: sensitization of skin (SH) 

ENVIRONMENT
 

NOTES
The name Chromic acid is used for this product, as well as for Chromic (VI) acid (CAS 7738-94-5) and for Chromium (VI) oxide (CAS 1333-82-0, see ICSC 1194).
The molecular weight may vary depending on the degree of hydration.
