Solubility in water: reaction 


EXPOSURE & HEALTH EFFECTS

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

Effects of short-term exposure
The substance is irritating to the skin and respiratory tract. The substance is corrosive to the eyes. 

Inhalation risk
A nuisance-causing concentration of airborne particles can be reached quickly when dispersed. 

Effects of long-term or repeated exposure
Repeated or prolonged contact with skin may cause dermatitis. Repeated or prolonged contact may cause skin sensitization. 


OCCUPATIONAL EXPOSURE LIMITS
TLV: (respirable fraction): 1 mg/m3, as TWA; A4 (not classifiable as a human carcinogen).
MAK: carcinogen category: 3 

ENVIRONMENT
 

NOTES
The product is primarily a mixture of calcium silicates, aluminates, ferrites and calcium sulfate.
An added stabilizer or inhibitor can influence the toxicological properties of this substance, consult an expert.
Sensitization observed with cement is mainly due to the presence of hexavalent chromium. Some Portland cements may be free of hexavalent chromium.
In the presence of moisture, skin burns may occur 12 to 48 hours after exposure; there may be no pain at the time of exposure.
