Cadmium Sulfate

The major hazards encountered in the use and handling of cadmium sulfate stem from its toxicologic properties. Toxic primarily by ingestion and inhalation, exposure to this odorless, colorless-to-white, crystalline substance may occur from its use as a fungicide, a cement accelerator, and a chemical intermediate in the manufacture of plastic stabilizers and pigments. Effects from exposure may include headace, shortness of breath, chest pains, kidney damage, liver damage, emphysema, chronic bronchitis and pulmonary edema (possibly resulting in death). Processes and operations which may release cadmium fumes or dust should be enclosed and fitted with exhaust ventilation. In activities where over-exposure is possible, workers should wear a high efficiency particulate filter respirator or self-contained breathing apparatus. Protective clothing also should be worn. Preferably this should include disposable one-piece suits (close-fitting at ankles and wrists), gloves, hair covering, and overshoes. These should be removed before leaving work. If contact should occur, immediately wash contaminated skin with large amounts of water. Do not eat, smoke, or drink in work areas. Cadmium sulfate presents only a moderate fire hazard (when in the form of dust) if exposed to heat, flame, or by chemical reaction with oxidizing agents, metals, hydrogen azide, zinc, selenium, or tellurium. Wear a self-contained breathing apparatus when fighting such fires. Cadmium sulfate should be stored in cool, well-ventilated areas, out of direct rays of the sun, and away from fire hazards. If hazardous concentrations of cadmium sulfate are accidentally released, remove all ignition sources, ventilate the area, and collect the released material in closed containers for disposal. Before implementing land disposal of waste cadmium sulfate, consult environmental regulatory agencies for guidance.

CLASSIFICATION: B1; probable human carcinogen. BASIS FOR CLASSIFICATION: Limited evidence from occupational epidemiologic studies of cadmium is consistent across investigators and study populations. There is sufficient evidence of carcinogenicity in rats and mice by inhalation and intramuscular and subcutaneous injection. Seven studies in rats and mice wherein cadmium salts (acetate, sulfate, chloride) were administered orally have shown no evidence of carcinogenic response. HUMAN CARCINOGENICITY DATA: Limited. /Classification based on former EPA guidelines/

Cadmium Sulfate reactivity

CADMIUM SULFATE acts as a weakly acidic inorganic salt, which is soluble in water. The resulting solutions contain moderate concentrations of hydrogen ions and have pH's of less than 7.0. They react as acids to neutralize bases. These neutralizations generate heat, but less or far less than is generated by neutralization of inorganic acids, inorganic oxoacids, and carboxylic acid. They usually do not react as either oxidizing agents or reducing agents but such behavior is not impossible. Many of these compounds catalyze organic reactions.
