Potential Exposure
(dibasic): Sodium arsenate is used in dyeing and printing; making other arsenates; as a germicide; in dyeing with turkey-red oil.
First aid
If this chemical gets into the eyes, remove any contact lenses at once and irrigate immediately for at least 15 minutes, occasionally lifting upper and lower lids. Seek medical attention immediately. If this chemical contacts the skin, remove contaminated clothing and wash immediately with soap and water. Seek medical attention immediately. If this chemical has been inhaled, remove from exposure, begin rescue breathing (using universal precautions, including resuscitation mask) if breathing has stopped and CPR if heart action has stopped. Transfer promptly to a medical facility. When this chemical has been swallowed, get medical attention. Give a slurry of activated charcoal in water to drink and induce vomiting. Do not make an unconscious person vomit. Antidotes and Special Procedures: For severe poisoning, BAL have been used. For milder poisoning, penicillamine (not penicillin) has been used, both with mixed success. Side effects occur with such treatment and it is never a substitute for controlling exposure. It can only be done under strict medical care.
Shipping
UN1685 Sodium arsenate, Hazard Class: 6.1; Labels: 6.1-Poisonous materials.
Incompatibilities
Sodium arsenate reacts with moisture, steam, and water; forming flammable and toxic arsenic hydride. Incompatible with oxidizers (chlorates, nitrates, peroxides, permanganates, perchlorates, chlorine, bromine, fluorine, etc.); contact may cause fires or explosions. Sodium arsenate is a weak oxidizing agent that may react with reducing agents, including hydrides. Keep away from alkaline materials, strong bases, strong acids, oxoacids, epoxides, chemically active metals. Arsine, a very deadly gas, can be released in the presence of acid, acid mists; or hydrogen gas. Attacks many metals (such as aluminum, iron, and zinc) in presence of moisture producing arsenic and arsine fumes
Waste Disposal
Dissolve in minimum quantity of concentrated, reagent hydrochloric acid. Filter if necessary. Dilute with water until white precipitate forms. Add just enough 6M HCl to redissolve. Saturate with hydrogen sulfide. Filter, wash the precipitate; dry, package, and ship to the supplier.
