An electrical danger sign board made from an aluminum plate is a safety precaution commonly used to alert individuals to the presence of electrical hazards. The sign typically features a rectangle shape, with a bold warning symbol such as a lightning bolt or a warning triangle, often accompanied by text like “Danger: High Voltage” or “Electrical Hazard.”

The use of aluminum for the plate provides durability and resistance to weather, making it suitable for both indoor and outdoor installations. The rectangular design ensures visibility and can accommodate clear, large text and symbols to communicate the hazard effectively.
