(a) Containers must be stress relieved after fabrication according to the code; or
(b) Cold-formed heads, when used, must be stress relieved; or
(c) Hot-formed heads must be used.
(3) Welding to the shell, head, or any other part of the container subject to internal pressure must be according to the code. Other welding is permitted only on saddle plates, lugs, or brackets attached to the container by the container manufacturer.
Containers used with systems covered in subsection (4) of this section must be constructed and tested in accordance with the DOT specifications.
(4) Containers must comply with department of transportation specifications and must be maintained, filed, packaged, marked, labeled and shipped to comply with current DOT regulations and American National Standard Method of Marking Portable Compressed Gas Containers to Identify the Material Contained, Z48.1-1954 R1970.
