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.

    Before working on equipment that I judged to be high risk, or in doubtful condition, I would prefer to test to “true earth” and not just to the CPC or frame of a machine.

    Test to structural metalwork, or to a metallic pipe, or to the CPC of another circuit. if outdoors test to a metal fence or even to a temporary earth rod.

    This being AFTER the usual tests.

    Even the much derided neon screwdriver will detect a dangerous voltage between allegedly earthed equipment and true earth upon which the operator is standing.
