Grounding is a critical safety practice in electrical systems that serves multiple functions, but it does not eliminate all electric shock hazards. The primary purpose of grounding is to ensure safety by providing a safe path for fault currents, which helps protect individuals from electrical shocks during faults.

While grounding helps mitigate risks associated with electrical noise and can aid in reducing the impact of voltage spikes caused by lightning strikes, it does not prevent such events. Grounding systems can provide a pathway for lightning to dissipate harmlessly into the ground, but they cannot stop lightning from striking the structure in the first place. Similarly, while reducing electrical noise can enhance the performance of electronic equipment, sound grounding practices provide only a degree of reduction, but not a complete elimination of electrical noise.

The understanding is that while grounding significantly increases safety and system reliability, it cannot completely remove the risk of electric shock, as there may always be unexpected conditions or system failures present. Therefore, grounding plays a vital role in safety, but it cannot assure that all hazards related to electric shock are entirely eliminated.
