What is a high risk activity?

High risk activities have the significant potential for adverse safety outcomes if not planned and carried out in a systematic and integrated manner. Careful consideration must be given to the risks associated with the activity and the methods available to manage those risks.

The high risk activities scheme under the WHS (Mines) Regulation 2014 allows the regulator to review the arrangements for the proposed activity to assess the planning and controls.

How much notice is needed?

All mines must give seven days notice of electrical work on energised electrical equipment.

All underground mines must give the regulator:

  • twelve months notice of connecting electricity to the mine so that the total connected voltage underground is greater than 12,000 volts
  • three months notice of development of a new mine entry (including by sinking a shaft or drift or raise boring) other than at an opal mine. Mine entry does not include a borehole of 500 mm or less in diameter drilled to support a mining activity, such as for removing water from a mine (transitional arrangements are in place for non-coal underground mines).

A range of other matters are high risk activities for coal mines. A range of notice requirements also apply to health risk assessments for coal mines.

How do I notify a high risk activity?
