High Voltage Warning Signs

Electric and Hybrid Vehicle High Voltage Warning Signs provide a clear and highly visible method of communicating restricted access in EV service and charging environments. Designed for use with barrier chains, posts and retractable barriers, these signs reinforce safety protocols by clearly indicating the presence of high-voltage systems and controlled work zones.

By displaying prominent “Danger – High Voltage / No Access” messaging, the signs help prevent unauthorised entry into EV service bays during diagnostics, battery isolation or charging operations. This visual reinforcement is critical in busy workshop environments where multiple teams, visitors or customers may be present.

Available in a variety of formats, sizes and custom configurations, these warning signs can be tailored to suit specific workshop layouts, branding requirements or OEM safety standards. They form an essential component of a comprehensive EV safety and access control system.
