What should be ensured before personnel utilize wrist straps connected to ground?

Before personnel utilize wrist straps connected to ground, it is essential to ensure that the equipment is de-energized. This is crucial because wrist straps are used to safely dissipate any electrostatic discharge that could potentially damage sensitive electronic components. If the equipment is still energized, there is a risk of electrical shock or short circuit incidents, which can pose serious safety hazards to personnel handling the equipment.

De-energizing the equipment ensures a safe working environment, allowing personnel to perform their tasks without the risk of electric shock. This procedure is a fundamental safety measure when working with any electrical or electronic systems, especially in environments that require grounding techniques to protect sensitive components from electrostatic discharge.
