78 Operator controls

(1) A designer of plant must ensure that the design provides for any operator controls for the plant to be—

(a) suitably identified on the plant so as to indicate their nature and function; and

(b) located so as to be readily and conveniently operated by each person using the plant; and

(c) located or guarded to prevent unintentional activation; and

(d) able to be locked into the "off" position to enable the disconnection of all motive power.

(2) If the need for plant to be operated during maintenance or cleaning cannot be eliminated, the designer of the plant must ensure that the design provides for operator controls that—

(a) permit operation of the plant while a person is undertaking the maintenance or cleaning of the plant; and

(b) cannot be operated by any person other than the person who is carrying out the maintenance or cleaning of the plant; and

(c) allow operation of the plant in such a way that any risk associated with the activities to any person who is carrying out the maintenance or cleaning of the plant—

(i) is, so far as is reasonably practicable, eliminated; or

(ii) if it is not reasonably practicable to eliminate the risk, is reduced so far as is reasonably practicable.

(3) This regulation does not apply to an emergency stop device.
