Can I use any harness for confined space entry using a tripod and winch system?

Any harness with a front and/or back D-ring attachment can be used for confined space entry applications. If using a hoist for lowering a worker into a confined space, you may attach the hoist to the front D-ring if that is a feature on the harness. This allows the worker to be lowered in a comfortable sitting position. Connecting to the rear (dorsal) D-ring on the harness is normally suggested because if a rescue is ever required, the lift position has less chance of interfering when being hoisted-from/exiting the confined space opening.
