TUC Brown Book
This is the TUC version approved by the HSE for training union safety reps. A number of the regulations have been updated.
One important point to note is that the HSE Brown Book in its previous pocket-able envelope sized format no longer exists and has been replaced by an A4 book headed 'Consulting Workers on Health and Safety' and it incorporates both the SRSC Regs 1977 and the Health and Safety (Consultation with Employees) Regulations 1996.
However the Health and Safety (Consultation with Employees) Regulations 1996 is not contained in the TUC's Brown Book (the SRSC Regs are relevant to workplaces where the GMB is recognised by the employer under Section 30(1) TULRA 1974, See Reg 2 of Brown Book).
