Fatal Incident - Safe Isolation failure?

jbrameld

What do we think on this incident, reported a bit differently in these two locations:

Whilst very sad and no-one should lose their life in the workplace (or anywhere else) I can't help thinking that an engineer of 30 years' experience should have been familiar with safe isolation procedures, and perhaps these were not followed.  There are of course many unreported possibilities such as multiple supply sources not identified but if you follow the mantra of poking a verified test device probe in before anything else (like your fingers or a screwdriver….), then your chances of falling victim are much reduced.

    Mike's comments remind me of an incident many years ago when wound ballasted fluorescents were popular.

    A batten fluorescent fitting in a domestic garage was misbehaving. I was up a metal  step ladder having an initial look and fiddle. I received a mild but unpleasant shock.

    The terminal block inside had three terminals. L. E. and N.  E. was connected via a small metal tab to the metal batten body and was designed to be the earth terminal.

    A clown had connected the E. terminal to the permanently live loop conductors. Earth (C.P.C.) was not connected at all.

    I was saved by the fact that the steps had plastic feet on them.

    I have found the same issue with fluorescent lights several times.
