(2) BUBBLE TEST is the application of a soap solution, detergent, aerosol spray or similar material that promotes the formation of bubbles at the site of any potential LPG vapor leak source and observing for bubbles. (3) CARGO TANK is a container that is used to transport LPG and is either
mounted on a conventional truck chassis or is an integral part of a cargo transporting vehicle, such as a bobtai l, mobile fueler or rail tank car. (4) CONNECTOR is any component, including an adapter, hose, fitting, valve or coupling that is used to facilitate the transfer of LPG from one container to another, and that is disconnected following completion of an LPG transfer or dispensing activity.
