5 FIRST AID Poisoning-gaseous LPG When refueling, avoid LPG vapor inhalation - danger of suffocation. The injured person must be taken out of the contaminated area. Attention! Fire and explosion hazard! LPG is not poisonous, but is suffocating. In case of breathing failure carry out apply artificial breathing immediately. In case of blood circulation failure combine artificial breathing with indirect heart massage. Transfer the affected person the heath facility immediately. Frostbites-liquid LPG In case of steep drop of overpressure to the atmospheric pressure the liquid LPG is evaporated under the temperature of -42 C. Leak of the liquid LPG may result in frostbites, when in contact with the skin. Do not rub the frostbitten parts of the body, but cover by a sterile dressing and call the doctor. Eyes affected by LPG shall be flushed by plenty of water. Call the doctor. Burns-fire When burnt, cool the injury by cold water, do not lubricate, cover by a sterile dressing and call the doctor. Do not remove the dress. If the clothes are burnt - do not run, extinguish by water, blanket, by rolling about... Electrical Shock : If you suspect someone has received an electric shock you must ensure all power sources are isolated before you can treat the casualty. High voltage : Overhead power cables are an example of a power source generating high voltage electricity. High voltage electricity has the ability to jump or arc up to distances of 18 metres or over. If faced with a casualty resulting from high voltage electricity: Do not approach. Stay at least 25 metres away from the casualty until the power has been switched off by an official agency i.e. Electricity Board. Low voltage : If faced with a casualty who is in the process of receiving an electric shock you should: Attempt to turn the power off at the mains. Remove any cables/power tools etc., still in contact with the casualty. Insulate yourself from the ground with books / newspapers / rubber matting. Use an object of low conductivity i.e. a wooden broom or rolled up newspaper, to push away the power source 5
