WHMIS Classification

Class D, division 2B toxic material skin or eye irritant Class E, corrosive material forms alkaline solution with water •

Most important adverse effects

In contact with water, an alkaline solution will be formed (pH 11 – 11.5). In spite of the pH level, the alkaline reserve is limited and the product has not been classified as irritant according to the criteria defined in the EEC directives (93/21/EEC) A dust problem may occur in confined areas. It is regarded as nuisance dust without any known specific effects to health. • Specific hazards Calcium aluminates react chemically and harden when mixed with water. The reaction is exothermic resulting in a temperature rise. If large quantities of cement are exposed to sufficient quantities of water, steam can be formed and the temperature may increase enough to cause a risk of burns during the reaction. • Carcinogen listed in: Kerneos Inc. 1316 Priority Lane Chesapeake, VA 23324 Phone (757) 284-3200 - FAX (757) 284-3300 Page 2 (5) Calcium aluminate cement is not a listed carcinogen with NTP, OSHA or IARC monograph.
