(a) No repairs or alterations involving
					 flame, arc, or other method of welding shall be made on any container cylinder,
					 or system unless such container, cylinder, or system shall first have been
					 certified as gas free or oxygen free by a qualified person.
(b) No repair or alteration affecting the
					 safety of any container or cylinder shall be made until the contemplated repair
					 or alteration has been authorized by a qualified inspector. The owner or user
					 of the LP-Gas container shall ensure that the repair or alteration is performed
					 by a company with a valid ASME "U" or a National Board "R" Certificate of
					 Authorization. The exchange or interchange of valves, fittings, and accessories
					 intended for the same purpose shall not be considered a repair or
					 alteration.
(c) No container or
					 cylinder that has been subjected to a fire shall be returned to service until
					 it has been inspected by a qualified inspector and found to be safe.
Any container or cylinder which has suffered mechanical
						damage causing dents or other deformation exceeding a depth of 1 ½ times
						the thickness of the deformed head or shell or two percent of the container
						diameter, whichever is greater, shall be re-formed to its original shape or
						otherwise repaired as provided in these Orders.
(d) Any vessel requiring repair or alteration
					 or that has been subjected to a fire shall not be recharged until it has been
					 retested in accordance with the requirements for its original hydrostatic test
					 and found to be suitable for continued service, when such test is deemed
					 necessary by the qualified inspector.
(e) The owner or user of the LP-Gas container
					 shall ensure that all repairs or alterations affecting the safety of LP-Gas
					 tanks are reported to the Division within 21 days by the ASME "U" or National
					 Board "R" certificate holder making such repairs or alterations using the
					 appropriate National Board Form, "R-1", Report of Welded Repair, or "R-2",
					 Report of Alteration, or equivalent (See Appendix D). The owner or user shall
					 ensure that the qualified inspector stamps his/her certificate of competency
					 number adjacent to all welded repairs authorized by him/her, except that in the
					 case of repairs to quenched and tempered steels, this number need not be
					 stamped. This exception shall be noted in the inspector's report.

					 or alterations to containers shall be done by a welder qualified in accordance
