Warning - Arc Flash / Shock - Appropriate PPE and Tools Required - Safety Signs by Caledonia Signs

Inform personnel that working near or on electrical equipment presents serious risks of arc flash and electric shock, and that specialised personal protective equipment (PPE) and tools are mandatory. Arc flashes can release intense heat, light, and pressure, while electrical shocks can cause severe injury or death. This sign ensures that only trained personnel equipped with the proper insulated tools, gloves, face shields, flame-resistant clothing, and other PPE handle the equipment safely.

This sign should be placed in high-voltage areas, switchgear rooms, transformer rooms, control panels, electrical substation sites, and other locations with energized or exposed electrical systems. It should be displayed at entrances, on doors, and near the equipment itself so that anyone approaching the area understands the specific PPE and tool requirements before working. Placement at eye level and in clearly visible positions ensures maximum awareness and compliance.

The wording “Appropriate PPE and Tools Required” clearly communicates the safety expectation, while “Arc Flash and Shock Hazard” identifies the specific risks. This combination emphasizes the severity of the hazard and the critical need for proper safety preparation. Workers are reminded to follow electrical safety protocols, including lockout/tagout procedures and use of flame-resistant and insulated equipment.

Overall, using this sign is essential for preventing serious injuries or fatalities, maintaining regulatory compliance, and fostering a strong culture of electrical safety. It ensures that personnel approach high-voltage work with the correct protective measures and tools, minimizing the risk of accidents in hazardous electrical environments.
