To operate a MHF, you must hold a licence or the facility must be registered with WorkSafe pending the issue of a licence. There are specific obligations relating to these licences.
More on licensing
As an operator, you must identify all major incidents that could occur at the facility and all major incident hazards. You must then conduct a safety assessment of these potential incidents and hazards.
You must eliminate the risk of a major incident occurring. If it is not reasonably practicable to eliminate the risk, you must reduce it as far as reasonably practicable.
You are required to review (and, where necessary, revise) your risk management approach if things change, if control measures are deemed insufficient, if requested by a health and safety representative or if directed to do so by WorkSafe.
Operators also have a duty to develop an emergency plan, as well as a safety role for employees.
