Ken- to quote your post
"which, whilst not being prescriptive, does prove useful in letting you know what is expected by the enforcing authority".
There were as many different interpretations of the the old prescriptive guides as there were Fire Brigades, let alone formats for fire certificates, exemption certificates??? etc. Why should this be any different?
The new order and the old management regs are perfectly clear on what constitutes a suitable and sufficient risk assessment. The guidance makes the process crystal clear. As long as the assessment meets the criteria and the significant findings are expressed what difference does the format make? And what is wrong with letting the court decide?
Theres no prescribed format for a manual handling, coshh, working at heights, workplace, display screen regs etc etc risk assessment, the guidance sets out the matters to be considered and leaves the choice how it will be recorded to the assessor. Why should fire be any different?
