Where inhalation has occurred, the victim (who may be unconscious) should be removed to a well ventilated area. Rescuers should not put themselves at risk - a contaminated area should not be entered unless considered safe. Breathing apparatus may be required but should only be used by trained personnel. The person should be kept warm and rested whilst medical attention is obtained. If breathing has stopped then resuscitation should be commenced by a trained first aider.
Where contact has occurred, the aim should be to slowly raise the temperature of the affected area back to normal. For minor injuries, clothing should be loosened and the person made comfortable. Clothing should not be pulled away from burned or frozen skin. The affected area should be doused with copious quantities of tepid water (40°C) for at least 15 minutes and a sterile burn dressing applied to protect the injury until the person can be taken to receive hospital treatment.
For major injuries apply first aid as far as is practicable and arrange for the victim to receive medical attention.
