EFFECTS: Not available. TERATOGENIC EFFECTS: Not available. DEVELOPMENTAL TOXICITY: Not available. Repeated
or prolonged contact with spray mist may produce chronic eye irritation and severe skin irritation. Repeated or prolonged
exposure to spray mist may produce respiratory tract irritation leading to frequent attacks of bronchial infection.
Section 4: First Aid Measures
Check for and remove any contact lenses. In case of contact, immediately flush eyes with plenty of water for at least 15

In case of contact, immediately flush skin with plenty of water for at least 15 minutes while removing contaminated clothing
and shoes. Cover the irritated skin with an emollient. Cold water may be used.Wash clothing before reuse. Thoroughly clean
shoes before reuse. Get medical attention immediately.
Serious Skin Contact:
Wash with a disinfectant soap and cover the contaminated skin with an anti-bacterial cream. Seek medical attention.
If inhaled, remove to fresh air. If not breathing, give artificial respiration. If breathing is difficult, give oxygen. Get medical
Evacuate the victim to a safe area as soon as possible. Loosen tight clothing such as a collar, tie, belt or waistband. If
