Warning - Arc Flash / Shock Hazard - Safety Signs by Caledonia Signs

Alert personnel to the presence of electrical equipment or systems that pose a risk of arc flash and electrical shock. Arc flashes can occur when electrical energy jumps across a gap, releasing intense heat, light, and pressure, while electrical shock can cause serious injury or death. The sign provides a clear warning to ensure that only trained and authorised personnel approach or work on the equipment, and that proper protective measures are taken.

This sign should be placed in electrical rooms, switchgear areas, transformer rooms, control panels, high-voltage equipment zones, and industrial or commercial facilities with exposed or high-energy electrical systems. It should be positioned at entrances, on doors, and near the equipment to alert anyone approaching that specialised training, personal protective equipment (PPE), and safe work procedures are required before entry or interaction.

The wording “Arc Flash and Shock Hazard” clearly identifies the specific risks, while “Warning” signals that there is a serious potential danger. This combination ensures that workers and visitors understand the severity of the hazard and take the necessary precautions, such as wearing appropriate PPE, following lockout/tagout procedures, and maintaining a safe distance.

Overall, using this sign is crucial for preventing serious injuries or fatalities, ensuring compliance with occupational health and safety regulations, and fostering a culture of electrical safety. It communicates risk awareness effectively and supports the safe operation and maintenance of high-voltage and energized electrical systems.
