§ 47.62. Mechanical power transmission apparatus.
(a) Emergency stops. Emergency stops are not required in cereal mills, malt houses and grain elevators. The apparatus shall be arranged so that they may be stopped as a whole, as promptly as practicable, and in a manner which meets the approval of the Department.
(b) Guarding. The Department may upon written application grant an exception to the requirements as to guarding of individual shafts, pulleys and belts in basements containing only power transmission equipment and machines not operated from the basement, if there are no entrances to the basement from the exterior of the mill and if each entrance to the basement from the mill is equipped with a self-closing door or gate with a sign on it as follows:
DANGER
RUNNING MACHINERY
KEEP OUT
(c) Additional exception. In basements containing machines operated from the basement, the exception set forth in subsection (a) may be similarly granted for the shafts, pulleys and belts in that part of the basement in which there are no machines if the following conditions exist:
(1) There are no entrances to the basement from the exterior of the mill.
(2) A standard railing separates this part from that containing the machine.
(3) Each entrance to that part of the basement containing no machines has a self-closing door or gate with a sign on it as follows:
DANGER
RUNNING MACHINERY
KEEP OUT
(d) Overhead belts. Overhead belts with the lower part 7 feet or less from the floor or working platform level may be considered as guarded if located over a machine or other permanent construction, so that it is impossible for any one to pass between them.
