Why is the F2508 series of forms so called? Why didn't the opt for a simpler system i.e in an easier numerical system?

I wondered if it related to the original SI number of the first RIDDOR (or even NADOR before that) but no joy there.

I don't know why and I personally don't see that it matters. I don't think that anything about the number of form makes it difficult in any way whatsoever.

bigpub and walker,

In you search for answers, might be useful to look at the list of forms used by HSE,

https://www.hse.gov.uk/forms/formsindex.htm

within there you'll also find F2067, F2525, F2533, F2534, so there may be a trace back in time

That was my first thought!

BUT - F10 (CDM) by my reckoning is a much more recent document

Some followers of this thread may be interested to know that Form 1 was the reference for the poster comprising the abstract of the former Factories Act which for many years had to be displayed by law to employees in premises designated as factories under that Act. Though I may be 'ancient' by walker's definition at #4, I can't remember anyone in HSE ever explaining how the numbers were allocated. However, I do possess a copy of 'Redgrave's Health and Safety in Factories'. The footnotes about Form 1 list other obligatory posters ('prescribed forms') as Form 2 for docks, etc., Form 3 for construction sites and Form 3A for building operations at mines and quarries, so these posters were evidently the subject of a short rudimentary sequence.
