Guard nip points on belt conveyors.

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:
(1) Where the belt wraps around the pulley.
(2) At terminals, take-ups, and snub rollers where the belt changes directions at transfers and deflectors.
(3) At the discharge end.
(4) At other points where workers may be injured by nip or shear points.
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.
