(a) Before adjustments and repairs are started on a crane you must take the following precautions:

(ii) All controllers must be at the off position.
(iii) The main or emergency switch must be open and locked in the open position.
(iv) Warning or "out of order" signs must be placed on the crane, also on the floor beneath or on the hook where visible from the floor.
(v) Where other cranes are in operation on the same runway, rail stops or other suitable means must be provided to prevent interference with the idle crane.
(vi) Where temporary protective rail stops are not available, or practical, a signalperson should be placed at a visual vantage point for observing the approach of an active crane and warning its operator when reaching the limit of safe distance from the idle crane.
(b) After adjustments and repairs have been made you must not operate the crane until all guards have been reinstalled, safety devices reactivated and maintenance equipment removed.
