Hi there Mr Stone 

Could you elaborate as to why you've shared this document in your question in the Wiring Regs forum? There's not much to go on! 

Edit: I'm changing the format of this question to a discussion as there's no question raised by the author. I'm going to hazard a guess that it's a paper they've written and they'd like some feedback on it? 

I’m still trying to guess the question, however as a comment I’ll add:

I think that as a society, we need more desensitization and not less. Just look at the poor Royal Lady In Waiting for example.

I think you have a point in that the perception of risk is very often differs quite significantly from the actual risk - and sometimes that can be true for the people wiring the safety procedures as well as those that are meant to follow them. Certainly there's a tendency to "get used to" situations and accept the associated risks, regardless of the actual statistics. Often life forces that sort of attitude - if we thought logically we probably wouldn't even get to work since the hazards of road travel are often much higher than anything we're exposed to once at work. I can see that it might be a "challenge" to get people to think differently once they're crossed the threshold into a workplace.

(Correcting some of the more obvious grammatical/spelling errors might make the paper easier to read - e.g. don't use possessive 's for plurals, or shear instead of share)
