Section 296-806-42062. Guard screw conveyors.

Latest version.

(1) You must enclose the rotating screw to prevent contact with the shear points where it passes the sides of the trough or casing.

(2) You must guard screw conveyors requiring an open housing by using one of the following:

(a) Make sure safeguarding by distance meets these requirements, WAC 296-806-20056.

(b) Make sure guardrails used for safeguarding meet these requirements, WAC 296-806-20058.

(3) You must construct feed openings for shovel, front-end loader, or other manual or mechanical equipment so that the conveyor screw is covered by a grating. If the nature of the material is such that a grating cannot be used, then the exposed section of the conveyor must be guarded by a railing and warning signs.
