Quite so Wee Brian, that was the point I was making to John. The Order says the Responsible person must do it. Article 18 requires him to appoint competent persons "to assist him in undertaking the preventive and protective measures."
Can't resist it - must get in my twopenneth
Much depends on the interpretation of the word "undertaking" in the above extract from Art 18 - and not surprisingly there is no defintion of "undertaking" in the RRO
If it means 'to implement' then it suggests that the preventive and protective measures have already been identified by the Responsible Person in his risk assessment - the RP has done it on his own - and the competent person shouldn't do it for him.
(The defintiion of 'preventive and protective measures' is clearly defined as those "identifed by the RP")
If "undertaking" means 'in identifying' then it would infer that the competent person can assist the RP in carrying out his RA.
If "undertaking" means "duty" then there's a personal pronoun missing - it should be "his undertaking" (the most likely intention - I think!)
and if it means "promise" or "assurance" it doesn't make sense ..... like most of it I'm afraid
