WAC 296-806-20010. Protect employees from unintentional machine operation
(1) You must make sure foot-operated controls are located or guarded so that unintentional movement to the " on " position is unlikely.
(2) You must make sure machines will not automatically restart when power is restored after a power failure, if restarting would create a hazard for employees.
Note:
Operating controls can be protected from unintentional movement by methods such as covers on foot treadles and collars around machinery start buttons.
