SECTION 4. FIRST AID MEASURES

4.1. Description of first aid measures
Skin contact: Remove all contaminated clothes and footwear immediately unless stuck to skin.
Drench the affected skin with running water for 10 minutes or longer if substance is still
on skin. Transfer to hospital if there are burns or symptoms of poisoning.
Eye contact: Bathe the eye with running water for 15 minutes. Transfer to hospital for specialist
examination.
Ingestion: Wash out mouth with water. Do not induce vomiting. If conscious, give half a litre of water
to drink immediately. If unconscious, check for breathing and apply artificial respiration if
necessary. If unconscious and breathing is OK, place in the recovery position. Transfer
to hospital as soon as possible.
Inhalation: Remove casualty from exposure ensuring one's own safety whilst doing so. If
conscious, ensure the casualty sits or lies down. If unconscious and breathing is OK,
place in the recovery position. If unconscious, check for breathing and apply artificial
respiration if necessary. If breathing becomes bubbly, have the casualty sit and provide
oxygen if available. Transfer to hospital as soon as possible.
4.2. Most important symptoms and effects, both acute and delayed
Skin contact: There may be redness or whiteness of the skin in the area of exposure.
Eye contact: There may be irritation and redness. The eyes may water profusely.
Ingestion: There may be soreness and redness of the mouth and throat. Ingestion of (excessive
amounts) may cause vomiting, nausea, convulsions. There may be loss of
consciousness.
Inhalation: There may be respiratory irritation. Harmful by inhalation
