Section 408.16237. Rotational molding.

Rule 6237. (1) A pinch point created where the revolving drive wheel of a rotational molding machine meets the driving surface shall be guarded.

(2)   The perimeter of the path of travel of the rotating molds shall be guarded by a standard barrier as prescribed in General Industry Safety Standard Part 2 “Floor and Wall Openings, Stairways, and Skylights,” as referenced in R 408.16202. Access into the area shall be by a gate or door. If the gate or door is interlocked to the power source, the guarding required in subrule (1) of this rule need not be installed. The interlocked gate or door on the standard barrier shall not be used as an operating control.

(3)   Such a machine, having each movement of the mold manually controlled by an operator, may substitute a yellow line 4 inches wide for a standard barrier around the perimeter of the path of travel of the rotating molds, except the perimeter between the heating and cooling chambers. However, movement of the molds shall be preceded by automatic activation of a warning device, such as a flashing light, bell, horn, or siren for 5 seconds before the movement.

(4)   The operating controls for a manually operated machine shall be so located that the operator cannot reach into the path of or be struck by the moving mold.
