Electric shock can result from the use of faulty electrical equipment or from the misuse of equipment in good condition.
Make sure that electrical equipment is maintained in good condition and frequently tested. Faulty equipment should be labelled and preferably removed from the work station.
Make sure that flexes, cables, plugs and sockets are not frayed, kinked, cut, cracked or otherwise damaged. If using cable reel extension equipment, ALWAYS ensure that the cable is fully unwound from the reel.
Make sure that electrical equipment and flexes do not come into contact with water.
Make sure that electrical equipment is protected by the correct rated fuse.
Never misuse electrical equipment and never use equipment which is in any way faulty. The results could be fatal.
Make sure that the cables of mobile electrical equipment cannot get trapped and damaged, such as in a vehicle hoist.
Make sure that the designated electrical workers are trained in basic First Aid.
In cases of electrocution:
EXHAUST FUMES
These contain asphyxiating, harmful and toxic chemicals and particles such as carbon oxides, nitrogen oxides, aldehydes, lead and aromatic hydrocarbons. Engines should be run only under conditions of adequate exhaust extraction or general ventilation and not in confined spaces.
GASOLINE (PETROL) ENGINE
There may not be adequate warning of odour or of irritation before toxic or harmful effects arise. These may be immediate or delayed.
GAS OIL (DIESEL ENGINE)
Soot, discomfort and irritation usually give adequate warning of hazardous fume concentrations.
FIBRE INSULATION
The fibrous nature of surfaces and cut edges can cause skin irritation. This is usually a physical and not a chemical effect.
Precautions should be taken to avoid excessive skin contact through careful organization of work practices and the use of gloves.
FIRE
Many of the materials found on or associated with the repair of vehicles are highly flammable. Some give off toxic or harmful fumes if burnt; others such as fluoroelastomers when burnt or damaged by excessive heat can break down and produce highly corrosive hydrofluoric acid - See Fluoroelastomers.
Should any material be in a burnt or overheated condition, handle with extreme caution and wear protective clothing when handling such items. Dispose of such material in accordance with local regulations.
Decontaminate and dispose of protective clothing immediately after use.
Observe strict fire safety when storing and handling flammable materials or solvents, particularly near electrical equipment or welding processes.
Make sure, before using electrical or welding equipment, that there is no fire hazard present.
Have a suitable fire extinguisher available when using welding or heating equipment.
FIRST AID
Apart from meeting any legal requirements it is desirable for someone in the workshop to be trained in First Aid procedures.
Splashes in the eye should be flushed carefully with clean water for at least ten minutes.
Soiled skin should be washed with soap and water.
In case of cold burns, from alternative fuels, place affected area in cool to cold water.
Individuals affected by inhalation of gases and fumes should be removed to fresh air immediately. If effects persist, consult a doctor.
If liquids are swallowed inadvertently, consult a doctor giving him the information on the container or label. Do not induce vomiting unless this action is indicated on the label.
