During transfer from a hook ladder to a grounded tower, a worker may experience a static shock. To bond onto the grounded tower, a worker should which action?

• A. Do a fast slap with the hand
• B. Touch with bare skin
• C. Use a bonding strap
• D. Climb without bonding

Answer: (A)

Static electricity can build up on you when you move between grounded metal structures. To prevent a shock, you need to bring your body to the same electrical potential as the tower before making a final grip. A fast slap of the hand against the grounded tower provides a quick, direct path for the static charge to flow to earth, immediately discharging you and reducing the chance of a spark when you complete the transfer. While a bonding strap can establish grounding, the rapid hand slap achieves bonding right at the moment of transfer. Touching with bare skin or climbing without bonding either leaves a potential difference or isn’t a practical, reliable bonding method in this scenario.
