191Emergency stop controls

191 Emergency stop controls (1) If plant is designed to be operated or attended by more than 1 person and more than 1 emergency stop control is fitted, the designer of the plant must ensure that the design provides for the multiple emergency stop controls to be of the "stop and lock-off" type so that the plant cannot be restarted after an emergency stop control has been used unless that emergency stop control is reset. (2) If the design of the plant includes an emergency stop control for the plant, the designer of the plant must ensure that the design provides: (a) for the stop control to be prominent, clearly and durably marked and immediately accessible to each operator of the plant; and (b) for any handle, bar or push button associated with the stop control to be coloured red; and (c) that the stop control cannot be adversely affected by electrical or electronic circuit malfunction.
