Danger - 11000 Volts - Safety Signs by Caledonia Signs

An extremely important safety warning used to indicate the presence of very high-voltage electrical equipment or power lines operating at 11,000 volts (11 kV). This level of voltage is typical in electrical distribution networks and industrial power systems. Because such high voltage poses an immediate and severe risk of fatal electric shock, arc flashes, and serious burns, the sign is critical for keeping people at a safe distance and ensuring that only highly trained and authorised personnel work near these installations.

These signs are commonly placed on electrical substations, transformer enclosures, high-voltage switchgear, and overhead power lines where 11,000-volt systems are present. The high voltage involved can cause deadly injuries even without direct contact due to electrical arcing, which means that even being too close to the equipment can be dangerous. The sign serves as a strong visual warning to prevent accidental entry, discourage tampering, and remind workers to use specialised protective equipment and strict safety protocols when performing maintenance or inspections.

In addition to protecting lives, the “Danger – 11,000 Volts” sign ensures compliance with stringent electrical safety regulations and standards that require clear marking of high-voltage hazards. Utilities and industrial sites must clearly identify these dangers to reduce the risk of accidents, legal liability, and service disruptions. The sign helps foster a culture of safety awareness and respect for the powerful and invisible forces within electrical infrastructure.

Overall, the “Danger – 11,000 Volts” sign plays a vital role in safeguarding both workers and the public from the deadly hazards of high-voltage electricity. It emphasises the extreme danger posed by these systems and promotes careful, informed behaviour around them. By clearly communicating the serious risk, this sign helps prevent accidents and supports the safe operation and maintenance of high-voltage electrical installations.
