These two (2) videos from the Solvent Industry Association (SIA) in the United Kingdom and the European Solvents Industry Group (ESIG) are by far the best series of videos on the practice of bonding and grounding. They can be found on the internet for non-members, but SAFTENG members can watch them below.
SPECIAL NOTE: in Europe and the UK they the word “earthing” to represent what we call “grounding” in the USA. All of the practices and hazards related to flammable liquids are UNIVERSAL.
These are another MUST SEE series of videos and be sure to check out these two great organizations for more info.
