2.3 Other hazards

Acute Toxicity Liquid and vapors react with moisture on the skin, eyes and mucous membranes to release a substance that is corrosive. Prolonged or repeated exposure and/or high concentrations of vapors will produce chemical burns and destruction of affected tissues. Respirable vapors or mist are irritating to the upper respiratory tract and bronchi. Inhalation may be fatal as a result of spasm, inflammation and edema of the lungs and larynx. Prolonged or widespread contact may result in the absorption of a potentially harmful amount of material.
