OBJECTIVE
Prevent electrical damage, overload, trip hazards and unsafe routing of extension leads.
WHY IT MATTERS
Temporary electrical leads can be damaged quickly by vehicles, pedestrians, sharp edges, water and heavy equipment.
Crushed or cut insulation can expose conductors and create electric-shock or short-circuit hazards.
Cable reels left coiled under high electrical load may overheat because heat cannot dissipate effectively.
Cables routed through access ways create trip hazards and are more vulnerable to mechanical damage.
Tape repairs, unsuitable multi-plugs and multiple daisy-chained extension leads are not acceptable permanent solutions.
REALISTIC SITE SCENARIO
An extension lead was routed across a vehicle crossing to supply a welding area.
No cable ramp was installed and several vehicles drove over the lead during the shift.
An evening inspection found crushed insulation with the conductor close to exposure.
Safe routing, cable protection and pre-shift inspection would have prevented the electrical hazard.
REMEMBER
Do not leave electrical leads unprotected across doors, roads or sharp edges.
KEY HAZARDS
Damaged insulation.
Crushed cables.
Overloading.
Overheated cable reels.
Trip hazards.
Water exposure.
Improvised connections.
Damaged plugs.
CONTROLS
Inspect leads before use.
Use RCD protection.
Use cable ramps at vehicle crossings.
Protect against sharp edges.
Fully unwind reels under high load.
Keep cables away from access routes.
Do not use taped temporary repairs.
Keep electrical leads dry.
Use correctly rated cables.
Remove damaged equipment from service.
SUPERVISOR MESSAGE
Team, temporary leads still require full electrical control. We will inspect cable condition, routing, rating and RCD protection, and any damaged or makeshift-repaired lead will be removed from service.
TEAM QUESTIONS
Is the cable undamaged?
Is RCD protection provided?
Does it cross vehicle routes?
Is the reel fully unwound?
Is water exposure possible?
Is cable capacity sufficient?
