Starting and stopping of electric motors

(1) Every electric motor shall be controlled by an effective switch or
switches for starting and stopping, and the switch or switches shall be so
placed as to be readily accessible to and easily operated by the person in
charge of the motor.

(2) Where a machine is used and driven by an electric motor, such efficient
means, suitably located, shall be provided for either stopping the machine or
switching off the electric motor as may be necessary to prevent
electrical hazard or other danger.

(3) Every electric motor shall be equipped with such efficient means so that
when stoppage occurs by reason of a fluctuation in voltage or failure in
supply of electricity the motor will not restart automatically in
circumstances whereby unexpected restarting is likely to cause
electrical hazard or other danger.
