Emergency & First Aid Procedures
Ingestion:
DO NOT INDUCE VOMITING. If conscious give water or milk to rinse out mouth and drink. Provide
liquid slowly but as much as casualty will drink. Transport to hospital or doctor without delay. Activated
charcoal may be helpful.
Eye contact:
Immediately hold the eyes open and irrigate eyes with running water for at least 15 minutes. Ensure
irrigation under eyelids by occasionally lifting the upper and lower lids. Transport to doctor or hospital
without delay. Removal of contact lenses after eye injury should only be undertaken by skilled personnel.
Skin contact:
Immediately remove all contaminated clothing including footwear (after rinsing with water). Wash affected
areas thoroughly with water and soap (to neutralize acidity of the product). Seek medical attention in
event of irritation.
Inhalation:
Remove to fresh air, lie patient down, keep warm and rested. If breathing is shallow or has stopped,
ensure clear airway and apply resuscitation. Administer oxygen. Transport to hospital or doctor.
Notes to physician: Treat symptomatically.
