Should contact occur, certain safety steps must be followed,<br />
depending on the kind of contact and the chemicals<br />
involved. Skin should be washed with soap and water.<br />
Chemical burns should have immediate medical attention.<br />
Eyes should be flushed at once with large amounts of water<br />
and immediate medical attention is mandatory. Hydrofluoric<br />
and fluorosilic acids cause painful burns and serious<br />
ulcers that are slow to heal. Immediately after exposure, the<br />
affected area must be flooded with water and emergency<br />
medical attention sought. Other materials that are especially harmful in<br />
contact with skin are concentrated nitric acid, sulfuric acid, chromic acid,<br />
30 and 50 percent hydrogen peroxide, sodium hydroxide, potassium<br />
hydroxide, bromine and anhydrous aluminum chloride, These materials also<br />
produce vapors that cause respiratory irritation and damage.<br />
