When working with static-sensitive electronic devices, what must you wear?

Wearing a grounding wrist strap is essential when working with static-sensitive electronic devices because it dissipates any static electricity that may build up on your body. This is important because static electricity can easily damage sensitive electronic components, leading to malfunctions or failure of the devices being worked on. The wrist strap is designed to create a direct path for any static charge to safely discharge to the ground, thus protecting the electronic components from potential electrostatic discharge (ESD).

In contrast, while conductive aprons and static-free gloves may provide some level of protection, they are not specifically designed to ground static electricity in the same effective manner as a grounding wrist strap. A safety helmet, although important for physical protection in electrical work environments, does not address the specific needs of controlling static electricity when handling sensitive electronic devices. Therefore, the grounding wrist strap stands out as the necessary equipment in these situations.
