Lockout, Tagout and Isolation

Isolating an electric vehicle is the easy part. Keeping it isolated while somebody else walks past the key is the part lockout exists for. A lockout system makes re-energising the vehicle a deliberate act by the person who isolated it, rather than an accident anybody can have.

A workable setup is a padlock per technician, a tag that names who applied it, and somewhere secure the service disconnect lives while it is out.

Common questions

Is lockout a legal requirement on EVs?

The Electricity at Work Regulations require precautions against danger from electrical equipment, and isolation that cannot be reversed by somebody else is how that is normally met. The regulations describe the outcome; lockout is the practical way to get there.

One padlock or one per technician?

One per technician, each with their own key. The point is that nobody can re-energise the vehicle while anyone is still working on it, and a shared lock cannot deliver that.

Where should the service disconnect go while it is removed?

Somewhere secured and signed, with the technician who removed it. Leaving it on the bench next to the car is how vehicles get re-energised.
