Demarcation of work zones in EV workshops

Retractable barriers to mark and cordon off the area around an electric vehicle during high-voltage maintenance. Customised belt with a message and electrical hazard pictogram, stable base, immediate deployment.

Signage and Demarcation

The barrier does not isolate the voltage; it marks the perimeter

Electric vehicles operate on 400 to 800-volt direct current batteries. Before working on the high-voltage system, the technical person applies the five golden rules of live-line work. The function of Dsafety in this context is not electrical isolation, but rather signage and demarcation: to comply with the fifth rule—demarcating the area and visually communicating that there is equipment inside that is off-limits to unauthorized personnel.

Role in the procedure

Cordon off the perimeter during lockout, do not electrically isolate it

While the technician performs the lockout—disconnecting the auxiliary battery, removing the service connector, waiting for capacitors to discharge—the work area must already be cordoned off. Dsafety barriers deploy in seconds and mark a visible perimeter around the vehicle and the lift.

The worker’s electrical protection is provided by dielectric PPE, procedures, and specific training. The barrier complements the procedure by making the boundary visible to those moving through the workshop.

Customisable tape

The printed message is the warning tool

The retractable tape is customised with the electrical hazard pictogram, warning text, and the workshop’s corporate colors. Dye-sublimation printing covers 100% of the surface. Anyone approaching the perimeter can clearly view exactly what type of zone they are entering.

Common messages: "DANGER — High Voltage," "Restricted Area — Work on HV Battery," "Authorized Personnel Only," orange color code for the high-voltage circuit.

Entry point

Where the belt ends, control begins

Regulation RD 614/2001 stipulates that work involving electrical hazards must be performed only by authorized and trained personnel. Barriers are placed leaving a defined opening: that opening is the access point, where the supervisor verifies the worker’s identity and dielectric equipment before allowing entry.

Can be combined with A4/A3 poster holders to display the vehicle’s rescue sheet, the lockout procedure, and the identification of the technician responsible for the disconnection.

The 5 golden rules and the barrier

The 5 golden rules of working on de-energized systems

Mandatory procedure before working on the high-voltage system of an electric vehicle. The retractable barrier complies with the 5th rule.

1
Disconnect
Turn off the contact, disconnect the 12V auxiliary battery, remove the service connector
2
Prevent backfeed
Store service connector in a safe place; prevent accidental reconnection
3
Verify absence of voltage
Wait for capacitors to discharge (5–10 min), measure voltage with appropriate equipment
4
Ground and short-circuit
Not applicable to EV — batteries cannot be grounded or short-circuited (IT network)
5
Cordon off and post warning signs
Cordon off work area, post hazard signs, restrict access to authorized personnel
