Under what circumstance is a fast slap with the hand used when bonding onto a grounded tower?

The use of a fast slap with the hand when bonding onto a grounded tower is particularly relevant during the transfer from a hook ladder. This action serves as a safety measure to ensure that the worker is properly grounded and that any potential electrical charge is safely dissipated before further work is performed. By slapping the hand against the structure, the lineman establishes a bond that helps to equalize any electrical potential between themselves and the grounded tower, reducing the risk of electric shock.

Contextually, this action is not typically employed when stepping onto the tower, as at that moment, the focus is usually on physical positioning and ensuring stability. Signaling for help, while important in emergencies, does not involve the specific action of bonding through a fast slap. Furthermore, during emergency situations, though the need for grounding and safety is heightened, the hand slap is specifically associated with the transition from a ladder to ensure immediate bonding, which is critical to preventing electrical hazards.
