| environment where the hazard of electric shock by arc welding is increased in relation to normal arc welding conditions
NOTE 1 – Such environment is found for example
a) in locations in which freedom of movement is restricted, so that the operator is forced to perform the welding in a cramped (e.g. kneeling, sitting, lying) position with physical contact with conductive parts;
b) in locations which are fully or partially limited by conductive elements, and in which there is a high risk of unavoidable or accidental contact by the operator;
c) in wet or damp or hot locations where humidity or perspiration considerably reduces the skin resistance of the human body and the insulating properties of accessories.
NOTE 2 – Environment with increased hazard of electric shock are not meant to include places where electrically conductive parts in the near vicinity of the operator which can cause the increased hazard have been insulated.
