(1) Barker feeding devices must be designed in such a manner that the operator will not be required to hold or make any physical contact with any log or bolt during the barking operations.
(2) A dog or locking device in addition to the motor switch, clutch, belt shifter or other power disconnecting device must be installed on all intermittent barking drums to prevent the drum from moving while it is being filled or emptied.

(8) Water wheel speed governor.
(a) Water wheels, when directly connected to marker disks or grinders, must be provided with speed governors, if operated with gate wide open; and
(b) Water wheels directly connected to pulp grinders must be provided with speed governors limiting the peripheral speed of the grinder to that recommended by the manufacturer.
