Why is knowledge of ESD important for technicians?

Knowledge of Electrostatic Discharge (ESD) is crucial for technicians because ESD can destroy many electronic components. When static electricity builds up on a person or an object and is discharged to sensitive electronic components, it can lead to immediate failure or degrade the performance over time, often without visible damage. Many modern electronic components are designed with very small structures that are sensitive to static electricity. If technicians understand how to handle these components properly, wear appropriate ESD protection, and maintain ESD-safe environments, they can significantly reduce the risk of damage to these components during installation, testing, or repair processes.

Other choices, while potentially relevant in different contexts, do not relate directly to the core issue at hand, which is the prevention of damage caused by ESD to electronic components.
