Rule 2370.
(1) Repair work to a die while in a press, or mechanical repair work to a press, shall not commence until power to the press pump motor is disconnected. Where multiple presses use a common power source, other means shall be taken to assure that no press motion can occur to cause an injury.
(2) Safety blocks shall be used when a die is being repaired while in a press.
(3) Means shall be provided to prevent cycling a press with the safety block in place between the upper and lower dies, or between the bolster plate and slide face, unless the safety block is of such design and material as to safely withstand the total press capacity.
