Hello
It depends on the solvent, heptanes and hexanes have issues with static build up especially when transferring the material. The best practice is either using grounding of both the receiver and the bottle where the material is being dispensed or transferring at a slow steady pace. Have observed a stream of hexanes go sideways if it was poured fast.
A colleague sent me this question and I suspect that the DCHAS-L list can provide helpful information. I’d appreciate any thoughts people would like to share on the topic...

Hello,
I have noticed an increase in the usage of 20L metals cans of solvents and wanted to include some safety tips in a talk I am doing. I know that grounding is required when you are transferring Metal to Metal or Metal to Plastic because of the buildup of static electricity but I was only able to find one University that has a requirement for also grounding glass bottles. I have never seen/experienced a shock from glass so I was not sure if I should make that a best practice requirement.
Does anyone have any thoughts or experiences with glassware or glass bottles building up a static charge?
