Ind. Code § 22-11-15-3
If a liquefied petroleum gas container bears on its surface in legible characters the name, mark, initials, or other identifying device of its owner, it is unlawful for any person except the owner or a person authorized in writing by him:
(3) to deface, erase, obliterate, cover up, or otherwise remove or conceal or change the name, mark, initials, or other identifying device of the owner or to place the name, mark, initials, or other identifying device of any person other than the owner on such container.
However, no written authorization shall be required during weather emergencies or at those times when the regular supplier of liquefied petroleum gas has failed, or is unable, to make delivery within a reasonable time.
