Underground cables

Working near to underground services

Underground service cables, especially cables containing electricity and gas, can be extremely dangerous.

Cables that are damaged from excavation or penetration of the ground (e.g. by a road pin) can cause serious injury.

  • Damage to electricity cables can cause a dangerous flash, leading to severe burns or even death.
  • Damage to gas pipes can cause gas leaks leading to fire and explosion.

Underground services may be commonly found in roads, footpaths, on sites or across open land. Always assume that they are present and treat any cable as 'live'.

Electrical accidents

Be aware that one service can often be mistaken for another, leading to dangeous sitautions, for example:

  • Cast iron gas can look like water mains.

Always check before you act!
