Welding in a Confined Space

Q: We have a weld joint that needs to be “fused” after machining.  The welder reaches into a 16” opening about 18” deep and welds this circumferential weld.  His feet never leave the floor; but his head is in the opening.  Based on OSHA’s definition of “entry” do we need to be concerned about this being considered a confined space?

A: Per 1910.146(b) "Entry" means the action by which a person passes through an opening into a permit-required confined space. Entry includes ensuing work activities in that space and is considered to have occurred as soon as any part of the entrant's body breaks the plane of an opening into the space.
