			 have a direct effect on the safety of the diving operations. Examples may
			 include but are not limited to: The supply of breathing air or gas; the supply
			 of materials, equipment or supplies required by this chapter; the maintenance
			 of diving equipment.
(2) This
			 standard applies to diving and related support operations conducted in
			 connection with all types of work and employments, including general industry,
			 construction, ship repairing, shipbuilding, shipbreaking and longshoring.
			 However, this standard does not apply to any diving operation:
(a) Performed solely for instructional
			 purposes, using open-circuit, compressed-air SCUBA and conducted within the
			 no-decompression limits;
(b)
			 Performed solely for search, rescue, or related public safety purposes by or
			 under the control of a governmental agency; or
(c) Governed by 45 C.F.R. Part 46 (Protection
