(a) Able to be locked in either the "off" or "on" position;

(b) Conveniently located with respect to the primary operating area of the equipment to allow equipment operators access to the switch; and

(3) You must make sure the powered platform equipment power supply is an independent electrical circuit that remains separate from all other equipment within or on the building.
