Electrical
Isolate supplies, prove dead and never work on exposed live parts.
FAULTNEST SAFETY
Know when to stop.
Troubleshooting is useful. Guessing around live electricity, gas, refrigerant, pressure vessels or structural damage is not.
Gas & Combustion
Do not remove sealed boiler covers or disturb gas components.
Refrigerant
Fridge, freezer and air-conditioning sealed systems require specialist equipment.
Water Damage
Isolate water quickly and keep clear of affected electrical equipment.
Structure
Large cracks, movement, sagging and unstable elements need professional assessment.
Stop Conditions
Burning smells, heat, arcing, gas odours, major leaks and repeated protective-device operation are not “carry on and see” moments.
