What voltage level is considered "high voltage" according to safety regulations?

The classification of "high voltage" in safety regulations is typically set at over 600 volts. This threshold is established because voltages above this level pose significant risks to personnel due to the potential for severe electrical shock and the increased likelihood of arc flash and other related hazards. Systems operating at these higher voltages require additional safety precautions, training, and protective equipment to minimize the risk of accidents and injuries.

In practical terms, the distinction is important for compliance with workplace safety standards, ensuring that workers are aware of the proper protocols when dealing with or near high voltage systems. This includes understanding the necessary Personal Protective Equipment (PPE), safety practices, and emergency response measures that must be employed when working with or around equipment operating above this voltage threshold.

Understanding this classification helps reinforce the importance of safety awareness in electrical work and ensures that training programs adequately address the risks associated with higher voltage systems.
