Utility providers / asset owners generally have safe approach distances (also known as safe working distances) and other conditions which need to be complied with when working in proximity to their assets.

Before any excavation takes place, workers must know what is underground and what is overhead.

Make sure mobile plant access and egress is safe by checking the proximity of overhead services and the ground strength for access routes (e.g. check for underground drainage pipes, service ducts, soak wells and storage tanks).

Contact the relevant authority regarding approach distances of nearby services.

Identify control measures that can be implemented to prevent any part of the plant or load from coming too close or contacting overhead powerlines.
