Safety Alert

What Happened

During a routine electrical inspection, multiple instances of damaged and poorly routed trailing cables were identified at the Power Station switchyard. Three cables had damaged outer sheaths exposing inner insulation, two cables were routed across vehicle access paths without cable crossover protection, and one cable was found to be in contact with a hot water pipe.

Why It Matters

Damaged cables and poor cable management create multiple hazard pathways including electrocution, fire, and arc flash. Cables in contact with heat sources can degrade insulation leading to electrical faults. Cables across access paths can be damaged by vehicles and create trip hazards. These conditions develop gradually and are often normalised — making them easy to overlook.

Immediate Actions Required

1. 1Damaged cables to be replaced or repaired immediately by licensed electricians
2. 2Cable crossover protection to be installed at all vehicle access points within 48 hours
3. 3Cable routing to be reviewed against AS/NZS 3000 requirements — separation from heat sources verified
4. 4Add cable management to the routine inspection checklist for the Power Station

Key Learning

Cable damage rarely happens suddenly — it develops over time through wear, heat exposure, and vehicle traffic. Regular inspections catch these issues before they become hazards. If you see a damaged cable, frayed sheath, or cable in an unusual location — report it immediately. Do not touch, move, or step over damaged cables.
