Ind. Code § 22-11-15-1
It is the intent of the general assembly to protect the public welfare and promote safety in the filling and use of pressure vessels containing liquefied petroleum gases by implementing both the interstate commerce commission regulations, within the state of Indiana, and the national standards of safety on the filling of these containers. It is necessary to insure that containers properly constructed and tested are used, and that a liquefied petroleum gas of suitable and safe vapor pressure be placed in these containers. Therefore, the filling or refilling of liquefied petroleum gas containers by other than the owner or authorized person must be controlled and specific authority to prevent violation and encourage enforcement should be established.
