According to safety standards, what action should be taken for electrically risky equipment?

The appropriate action for electrically risky equipment, according to safety standards, is that it needs to be grounded properly. Grounding is a crucial safety measure that minimizes the risk of electric shock or fire. By providing a path for electrical currents to return safely to the ground, grounding helps protect users from the dangers associated with equipment malfunction or faulty wiring. Proper grounding helps ensure that any stray currents are diverted away from individuals, thereby enhancing overall safety in environments where such equipment is used.

While other options may suggest alternative approaches, they do not adequately address the fundamental safety concerns associated with electrically risky equipment. Leaving equipment ungrounded would increase the risk of accidents, and saying proper training should prevent its use does not resolve the inherent hazards posed by electrical risks. Likewise, limiting repairs to manufacturers might not always be practical or necessary, as many qualified technicians can handle repairs as long as safety protocols, including grounding, are strictly adhered to. Proper grounding remains the most effective solution to mitigate risks related to electrical equipment.
