The wearhouse where I work is constantly being re-organized with very little attention placed on safety. There are areas of the building where forklifts pass through both fixed objects and employees either walking or working with no more than a few inches on either side.

What I was wondering is, in general what would be considered a min. safe distance when passing through or near various obstacles.

For example,
-between 2 pilars or walls (how much distance should there be on each side to pass through safely)

-between a fixed obstacle such as a pilar or wall and an area with pedestrians or workers
