Process: Hot Work
Hazard: Burns and Shocks
Welding leads and cables can become cut or crushed from the rough handling and usage they sometimes receive in shipbuilding and repair work. When the copper conductor is exposed as shown here, there is a real danger of electrical shock, especially in wet or damp locations.
This green tape repair to a damaged welding cable though well intentioned does not provide necessary insulation. This repair will not hold up very long to rough handling and usage or exposure to wet weather or wet locations.
Welding leads and cables should be inspected at the beginning of each work shift and more frequently when they are subjected to rough handling and usage, or are extremely lengthy. When a damaged lead or cable is discovered it should be immediately removed from service. Workers should never attempt to make on-the-spot or temporary repairs.
