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 that 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 aluminum 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 producing metal support, or covering the bottom edge with a suitable non-metallic material, such as an elastomer or a polymer, which will prevent sparking. |
