Hazard Illegal activity involving electricity
This hazard may exist where:
- The consumer unit has been tampered with to steal electricity
- There is direct wiring to doors or windows to create a booby trap
- Complex wiring is providing heat and illumination for drug laboratories or cannabis cultivation
- There has been attempted or actual cable theft
The impact of illegal activity involving electricity may extend far wider than a single building; it could, for example, affect power supplies to other buildings, disrupt train services or cause failures in telecommunications.
Control switches can indicate that the supply has been switched off, when actually it remains live. Therefore all electrical systems that may have been subject to illegal activity need to be treated with caution until made safe by a competent engineer.
