Which of the following is a practice to mitigate ESD?

Wearing grounded wrist straps is an essential practice for mitigating electrostatic discharge (ESD). These straps are designed to provide a path for static electricity to safely discharge to the ground, preventing the accumulation of static charges on the technician or the equipment. By using a grounded wrist strap, an individual can ensure that any static electricity is continuously dissipated, minimizing the risk of damaging sensitive electronic components during handling and assembly.

This practice is critical because many electronic components, particularly those in avionics systems, are highly susceptible to ESD, which can lead to operational failures or compromised functionality. Grounded wrist straps are an integral part of ESD control programs in environments where sensitive electronics are present, such as manufacturing or repair stations.

Other practices may help in managing ESD risks, but wearing grounded wrist straps provides immediate and direct protection against static discharge during work activities.
