WAC 296-806-42028   Guard nip points on belt conveyors.  

Exemption:

This rule does not normally require guards along the conveyor at the point where the belt rides on return rollers, such as return-belt idlers, unless hazardous conditions such as long, tight heavy belts exist.

Return-belt idlers

These turn freely and just idle.

     You must:

     • Place nip point guards at all of these points:

     – Where the belt wraps around the pulley.

     – At terminals, take-ups, and snub rollers where the belt changes directions at transfers and deflectors.

     – At the discharge end.

     – At other points where workers may be injured by nip or shear points.

Note:

The practice of applying a belt dressing or other foreign material to a rotating drive pulley or a conveyor belt is hazardous and should be avoided.
