More the suggestion that the air line itself, the plastic or rubber airline, has the potential (ha!) of building up static charge as result of the air blowing thru it.
And I’m thinking about spark from hose to van as you bring the hose up start the gas line cleaning. There might be some gasoline vapours around...
Maybe in reality the chance of sparking is low, i.e. plenty of alternate grounds.
You know how it is, one worries about gasoline fires.
Cheers
