Legislative requirements

Under the Mines Safety and Inspection Act 1994 and Mines Safety and Inspection Regulations 1995, for a mining operation (including exploration operations), the following must be reported to the department:

  • accidents involving injury to persons
  • occurrences (commonly referred to as notifiable incidents for reporting purposes).

What is a reportable accident?

Under section 76 of the Mines Safety and Inspection Act 1994, an accident on a mining operation must be reported if it causes an injury that prevents a person from returning to his or her duties as they were being performed at the time of the accident.

This covers situations where the person would be unable to return to those duties the following day, regardless of whether or not the person is rostered to work that day.

To whom and where does this apply?

This applies to:

  • company employees
  • self-employed persons
  • contractors
  • who, through their injury, have:
  • lost time from work
  • been assigned to alternate or light duties
  • been put on restricted hours.

Injury types

A serious injury is defined as an injury that:

  • results in the injured person being disabled from following his or her ordinary occupation for a period of two weeks or more, or
  • involves unconsciousness arising from inhalation of fumes or poisonous gases, or asphyxiation due to lack of oxygen or displacement of oxygen by an inert gas, or
  • results from an accident, including fuming, arising from the use of explosives or blasting agents.

If a fatality has resulted from an injury, it is classed as a serious injury.

A minor injury is a reportable injury that is not classified as serious.

What is a reportable incident?

Occurrences (also referred to as notifiable incidents for reporting purposes) are unplanned incidents that do not necessarily result in injury to a person or damage to property.
