Sorry to bring up this rather large elephant sitting in front of the fire. But, this chap who died was not an apprentice or trainee.
So, one would assume that the test equipment was supplied by the company and if so, he could have objected because it didn't conform to GS38?
His counter argument might be that if he had complained and refused to continue on the grounds of H&S then at the very least a black mark would be against him with a possible demotion, and at worst would be fired for lack of conformance to company 'policy'.

So perhaps the decision was right !

Unfortunate, since 53 is still young and a lesson to us all.

It seems that his probes had been stripped back. probably by him because they didn't fit into a terminal at some time ?

I recently needed a new voltage and continuity tester, and bought a nice cheep one from CPC made by Ideal. I must say I've been very impressed. One of the neat little features is that the probes have spring loaded shrouds, so terminal tunnels push it back, but once withdrawn they're fully insulated again. Why can't all probes be like that? Particularly the more expensive ones!

Well BS61010 only specifies that the insturument be protected and not the probes.
When using test instruments examining small current electronic PCBs, retractable probes seem to get in the way. A completely different matter when dealing with both higher voltages and currents.
I used to use a Fluke multimeter,- an instrument for all seasons. - but have found that I prefer a test lamp for checking voltages. I get an instant result without having to look directly at the readout.

I've got a fluke multimeter with two sets of probes. One set are the standard fluke ones with 20mm of exposed metal.

The other set are GS38. To be fair I don't use the multimeter very often on mains supplies, I tend to use my megger as it's better protected.

The martindale two lead voltage indicator is nice as the probe covers slide which overcomes the terminal issues.

No one will ever know what happened to the lift engineer but the probes must have been pretty well exposed to be able to make contact.

There are electricians out there who have never heard of GS38, so perhaps it is even less likely that a lift enginer would especially as their training might only deal with fault finding and safe isolation. The training might not go in to the depths of GS38 and the like ?
Let's hope it does now.
