What must be done at the earliest opportunity after a Taser handover?

The correct course of action following a Taser handover is to conduct a spark test and fill out the Taser register. Conducting a spark test is essential as it verifies that the Taser is functional and ready for use. This ensures that the device is operational and safe, which is critical for maintaining safety protocols when dealing with potentially dangerous situations. Filling out the Taser register is similarly important, as it provides a record of the Taser's use and custody, ensuring accountability and traceability within the equipment management system.

This initial verification and documentation step is crucial in maintaining compliance with safety procedures and operational readiness. Taking these actions promptly helps prevent any issues that might arise from using a malfunctioning device and ensures that all necessary records are accurately kept from the start.
