Static protection shall be provided to prevent static charges during which operation?

Static protection shall be provided to prevent static charges during which operation?

• A. Filling
• B. Transfer operations
• C. Spillage
• D. Pumping

Answer: (B)

Static electricity builds up when liquids move through hoses, pipes, and fittings, and a discharge can ignite flammable vapors in oil handling. Transfer operations are the phase where product is actively moved from one container to another, creating the most reliable conditions for charge to accumulate. To prevent ignition, static protection is applied during these transfers—bonding the source and receiving vessels, grounding the piping and equipment, and using conductive hoses to maintain a continuous path to earth. Spillage isn’t the stage where charges are generated, and pumping is part of transfer, but the essential time to guard against static is while the product is being transferred.
