Thanks for the informative references and guidance on grounding and bonding.  In addition to the information shared, it seems NFPA 77 and 29 CFR 1910.106 both address the issue.  We will be reviewing the information with an eye towards developing a guidance document for our folks.  I also really liked the poster and will definitely be ordering one or two!

Grounding wires usually have a spring clamp with either serrated teeth or a single point that will bite into the top rim/edge of the drum (through the paint). The other end of the wire can have the same spring clamp for bonding or be screwed into a metal strip attached to the wall which is hard connected to a building ground. Important to check resistance periodically to make sure there is none.

This really depends. What exactly are you trying to do? If you're running an electric current though something then rubber is going to be your best insulator/grounder.  As for a bonding material, this depends. You should be able to use almost any metal depending on its availability and the going rate of the metal. Just keep in mind the melting points and your safety.

Hi ,

I am looking for guidance on the appropriate method for grounding and bonding metal solvent containers such as 55 gallon drums or 5 gallon cans?
