What requirements apply to electrical control for maintaining and servicing farmstead equipment?

(1) You must ensure that only the employee maintaining or servicing equipment has control of the electrical power source by:
(a) Providing an exclusive, positive locking means on the main switch that can be operated only by the employee performing the maintenance or service; or
(b) For material handling equipment in a bulk storage structure, by providing on the equipment an electrical or mechanical means to disconnect the power. Minimum lockout means must meet the requirements of WAC 296-307-320.
(2) All circuit protection devices, including those that are an integral part of a motor, must have a manual reset, except where:
(a) A manual reset is infeasible because of the nature of the operation, distances involved, and the amount of time normally spent by employees in the area of the affected equipment;
(b) An electrical disconnect switch is available to the employee within fifteen feet of the equipment being maintained or serviced; and
(c) A sign, prominently posted near each hazardous component, warns the employee that unless the electrical disconnect switch is utilized, the motor could automatically reset while the employee is working on the hazardous component.
