First Aid Measures

Emergency procedures for chemical exposure incidents

Inhalation

If breathing has stopped, give artificial respiration. Get medical attention immediately. Remove to fresh air. Avoid direct contact with skin. Use barrier to give mouth-to-mouth resuscitation. Get immediate medical advice/attention.

Symptoms: May cause allergic respiratory reaction.

Skin contact

Avoid contact with UV and sunlight. In the case of skin irritation or allergic reactions see a doctor. Wash off immediately with soap and plenty of water for at least 15 minutes.

Symptoms: May cause an allergic skin reaction.

Eye contact

Rinse immediately with plenty of water, also under the eyelids, for at least 15 minutes. Remove contact lenses, if present and easy to do. Continue rinsing. Keep eye wide open while rinsing. Do not rub affected area. Get medical attention if irritation develops and persists.

Symptoms: May cause redness and tearing of the eyes.

Ingestion
