First Aid Information
Inhalation: Remove from exposure. If

artificial respiration. Obtain medical attention
urgently. Keep warm and at rest. If there is
difficulty in breathing give oxygen. Do not use
mouth to mouth ventilation.
Eye contact: Wash out eye for at least 15
minutes with plenty of water. Seek medical
attention.
Skin contact: Immediately flood the skin with
large quantities of water, preferably under a
shower. Remove contaminated clothing as
washing proceeds. Contaminated clothing
should be washed or dry-cleaned before reuse. Obtain medical attention if blistering
occurs or redness persists.
Ingestion: Wash out mouth with water. Give
sips of cold water or milk to soothe the affected
parts. Ingested acid must be diluted by
approximately x 100 to render harmless to
tissues. Do not induce vomiting. Obtain medical
attention.
