What’s the difference between in-running and outrunning nips?

In-running nips are defined as rotating shafts or rollers that can create a pull-in, trap point, or entanglement due to the direction of the motion into a stopped or stationary object. These situations shall be mitigated with power transmission covers and fabricated machine guards. 

Outrunning nips are defined as rotating shafts or rollers that create movement of an object or body part but away from danger or hazards. These situations can be harmless from pinch or crush points when avoiding contact with objects not in motion.  These situations should be evaluated as best practice situations to ensure proper workplace safety.
