Dear Chac,
Sorry, I forgot to revert.
2.4.3 is undoubtedly stolen from ISO. I think Cazx has given you a standard answer, full sets of Quality manual, Quality Procedures to the “Users” and the descending levels (though not meaning less important) as similarly appropriate. I was once asked regarding the detailed documentation supplied to the lady cleaning the toilets (always seems to be a lady, Caz, even in airports

). This did cause some head scratching but at least her flawless operational procedure approx. matched the manual and she could state the (documented) Company Policy.
A negative environment for 3.1.1.1 might be processing food next to a municipal rubbish dump. I have seen it happen after braving the resident fly population to do an inspection. Didn’t pass of course.
Have seen 3.2.1.9 applied to frozen cooked food where there must be a transfer point from raw to cooked (ie low to high risk) and a physical barrier is mandatory for separation of the two varieties / production personnel etc (including buckets) . Similar logic can be applied to frozen raw materials / frozen raw finished product although the risk differentiation is a bit more arguable.
