Risk factors for static electricity developing on a plastic pipe:
(1) installing and handling the plastic pipe
(2) repairing or working on the plastic pipe
(3) particulates in the flowing gas
(4) particulates outside the pipe passing over it (in the air, during excavation)
(5) hole in the wall allowing gas to escape
(6) connectors or flow valves that create turbulence in flowing gas
Development of static electricity is enhanced when there is:
(1) low humidity
(2) lack of adequate grounding
Grounding may be achieved by:
(1) wrapping the pipe in moistened cloth
(2) having a copper grounding wire running along the pipe
