Earthing clamps and cables
When working in the company with highly flammable liquids, we always recommend earthing* the container. After all, when siphoning (chemical/inflammable) liquids, the smallest spark can cause static electricity. Also always ensure that the receptacle is connected to the container so that it is also earthed when filling.
*explanation in a box: As is common knowledge, an earthing protects against electrocution.
