What is the recommended practice to prevent electrostatic discharge (ESD) during module installation?

Wearing grounded wrist straps is a critical preventative measure against electrostatic discharge (ESD) during module installation. Grounded wrist straps connect you directly to the ground or a grounded surface, ensuring that any buildup of static electricity is safely dissipated. This helps to protect sensitive electronic components within the modules from potential damage that can be caused by ESD.

Grounding yourself minimizes the risk of damaging these components due to a sudden discharge of static electricity that could occur if you touch them directly without proper ESD protection. This practice is especially important in environments where electronic equipment is handled frequently, as static electricity can accumulate from various sources, including clothing and synthetic materials.

While other options such as using plastic gloves, keeping the module in an antistatic bag, and disconnecting power from the switch can also contribute to ESD safety, they do not provide the same level of direct protection to the individual handling the equipment as wearing a grounded wrist strap does.
