What does a "high-voltage warning sign" indicate?

A high-voltage warning sign indicates the presence of high-voltage electrical equipment within a specific area. Such signs serve as critical safety measures to alert individuals to the potential hazards associated with high voltage, which can pose serious risks including electrical shock or arc flash incidents. The warning signals that extra caution is necessary when working or moving in proximity to this equipment, as improper handling or negligence can lead to severe injury or even fatality.

By indicating areas with high-voltage equipment, these signs effectively help in ensuring that only trained personnel who understand the associated risks and safety protocols are allowed to enter, thereby reducing the likelihood of accidents.
