An LP gas tank is adapted to permit it to be safely moved across concrete floors and rocky ground that may contain flint or other hard siliceous material tha t can generate sparks if struck with a metal, such as steel. The tank is capable of storing the gas under pressure. In addition to a pressure regulator and valve for filling and emptying, the tank also includes a base support. The base support usually is a steel or aluminu m base ring. If the tank is dropped on or slid along the floor, it may cause a spark that can trigger a fire or explosion in the presence of gaseous vapors. This problem is solved by either replacing the metal base support with a non-metallic or a non-spark producin g metal support, or covering the bottom edge with a suitable non-metallic material, such as an elastomer or a polymer, which will prevent sparking.
