If more than one Category 1 responder which has functions which are exercisable in a particular F1co-ordination area is subject to a particular duty under section 2(1)(a) to (f) in relation to an emergency or an emergency of a particular kind, paragraph (2) applies.

Where this paragraph applies, the Scottish Category 1 responders referred to in paragraph (1) may co-operate with each other and general Category 1 responders referred to in paragraph (1) for the purpose of identifying which of them will be the Category 1 responder with lead responsibility for performing that duty in relation to that emergency or an emergency of that particular kind in that F1co-ordination area.

If, pursuant to paragraph (2) and analogous provision in regulations made by a Minister of the Crown under Part 1, one of the Scottish or general Category 1 responders referred to in paragraph (1) is identified as being the Category 1 responder with lead responsibility for performing a duty under section 2(1)(a) to (f) in relation to an emergency or an emergency of a particular kind in a particular F1co-ordination area, the other Category 1 responders in that F1co-ordination area which are subject to that duty in relation to that emergency or an emergency of that particular kind are referred to in these regulations as “non-lead Category 1 responders”.
