Operational controls

If the need for plant to be operated during maintenance or cleaning cannot be eliminated, the person with management or control of the plant at a workplace must ensure that the operator’s controls —
(a) permit operation of the plant while a person is undertaking the maintenance or cleaning of the plant; and
(b) while the plant is being maintained or cleaned, either —
(i) cannot be operated by any person other than the person who is carrying out the maintenance or cleaning of the plant; or
(ii) if subparagraph (i) cannot be complied with because the plant must be operated by a person other than the person who is carrying out the maintenance or cleaning of the plant, cannot be operated except by a person authorised by the person with management or control of the plant for that purpose;
and
(c) will allow operation of the plant in such a way that any risk associated with the activities in relation to any person who is carrying out the maintenance or cleaning —
(i) is eliminated so far as is reasonably practicable; or
(ii) if it is not reasonably practicable to eliminate the risk, is minimised so far as is reasonably practicable.
