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.

    You could take a lead from SSE jointers. They were blue neoprene examination gloves when working, as they will protect from non-piercing direct contact, such as brushing a conductor or slipping when using insulating tools. I have some extra tough orange neoprene ones which might be even better, as seen on certain car maintenance videos, being made from synthetic rubber. Any additional safety feature is a good idea and these gloves still give excellent dexterity, unlike the gum-rubber insulating gloves for fuse changing live,  etc. I agree with John too, the volt-stick pens are much better than a two-pole tester, they work on the electric field between true Earth and live parts, check before and after use on a known live cable. Although many people don't seem to like them, the neon screwdriver works nearly as well as a volt stick, and is still VDE certified as safe to use. However, I can offer no guarantee of 100% reliability of any to these things, but that is not really what you are wanting is it?
