Tottaly agree with Phil here, have recently audited a LA large primary school under the Fire (Scotland) Act, the headteacher in my scenario, most certainly did have control over the day to day running of the school, but is only issued an annual budget like all other heads in LA schools in my area, for repairs and maintenance purposes, when asked if that also refered to repairs and maintenance to fire safety measures, I was told it doesn't
So for me this head is most certainly a RP (dutyholder) in Scotland, but as he is not the employer, his Employer is the primary dutyholder, for the safety of all employees and other relevent persons, and responsible for conducting the FSRA.
The headteacher has fire safety responsibilities in my case, but only to the extent of matters within his control,
So unless its different south of the border, thats how it is here, anyone who has control to any extent of premises will have some responsibilities for ensuring that those occupying the premises are safe from harm caused by fire.
The greater the degree of control, the greater the responsibilities.
