Grounding Non-Flammable Materials and Static from Totes

Grounding Non-Flammable Materials and Static from Totes

Grounding Non-Flammable Materials and Static from Totes

(OP)
Good afternoon,

I have two static related questions.

First, we have two different locations at our site where we unload flammable materials from tank trucks to bulk storage. At each of these locations we have static grounding indicator stations.

We have a third location where we unload 50% caustic from tank trucks to the bulk storage tank.

During a recent HAZOP of a process which uses caustic, the subject of not having a grounding station for this tank truck arose. In our case we go through stainless piping to a poly tank, and the bulk tank, being poly is not grounded or bonded.

Is there some true hazard here that I am missing? Is it a good practice to ground non-flammables anyway?

My second question is we occasionally handle 250 gallon poly totes. These poly totes have an aluminum support cage around them. After emptying we would rinse these with a spray nozzle. Even though we would have a ground wire connected to the aluminum cage, it was my experience that getting within 4 - 6 inches of the tote while the spray was going would produce enough static to produce a spark. Is there any better method for grounding these totes? I was considering having the plastic nozzle replaced with a metal one and having that grounded to the cage.

Thank you all.
