There are some points that could contribute to electrical accident when using portable electrical equipment (IGC2 Unit-5)

Causes of portable electrical equipment accident:
* Uning unsuitable equipment, e.g- the use of non-intrinsically safe equipment in a flammable atmosphere.
* Using equipment in wet, damp or humid conditions.
* Misuse, e.g- Stricking wires directly into a socket rather than using a plug.
* Physical abuse, e.g- Pulling the plug out by tugging at the flex, carrying the tool by the flex; Allowing the flex to be pinched, trapped or crushed, driving over the flex etc.
* Repairs carried out by unauthorised personnel or carried out badly, e.g- split flex taped up with insulating tape.
* Continued use of faulty, defective equipment.
* Chemical damage to the flex, e.g by corrosive wet cement.
* Lack of routine inspection, testing or maintenance.
