Hazard Identification

Emergency overview: Irritant. Irritating to eyes, respiratory system and skin

Eye: Causes eye irritation.

Skin: Causes skin irritation.

Ingestion: May be harmful if swallowed. May cause digestive tract irritation.

Inhalation: May be harmful if inhaled. Is irritating to mucous membranes and the upper respiratory tract. As far as is known, the chemical, physical and toxicological properties have not been thoroughly investigated.

Skin: In case of contact, immediately wash skin with mild soap and copious amounts of water. Flush skin for at least 15 minutes. Seek medical attention.

Ingestion: If swallowed, wash out mouth with water provided person is conscious. If victim is alert and conscious, give one cupful of water. Seek medical attention.

Inhalation: If inhaled, remove to fresh air. If breathing is difficult, give oxygen. If not breathing, give artificial respiration.

Notes to Physician: Treat symptomatically and supportively.
