Smartwatch that can detect electrocution?

[MarkT]

Hello folks,

I and a few others will be working with high power inverters, high voltage batteries (up to 1000 VDC) with very high power (up to 200 kW), in a lab, and sometimes we will be alone.

In which case you should not have any hand/wrist metal jewelery or watch on due to the short-circuit hazard these introduce?

It one thing to get a shock but having molten/vaporizing metal as well isn't going to help!

Surely this is a situation for a lock-out system?
