N O T E S
|
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.
Card has been partially updated in February 2009: see Occupational Exposure Limits.
