Bonding and grounding are needed when dispensing flammable liquids from storage drums to smaller electrically conductive containers. Similarly, whenever you transfer these liquids between conductive containers in any work area for example, when filling or draining dip tanks, mixers, rinse tanks or other equipment, bond both containers together and ground one of them.
Flammable gas systems should be grounded and bonded. Piping and gas bottles should protected from static charge buildup.
This factsheet describes how to apporopriately bond and ground items to ensure safety.
