For many in-house FR assessors the first step is the NEBOSH fire and risk management course. I did the course a number of years ago and it was populated mostly with office-bound people with third level education but with little knowledge of building construction or engineering and safety services. They were good at absorbing the plethora of facts and figures that the course spewed out and were happy with management protocols but they were not so good at the technical side. Few would have any understanding of building regulations relating to any aspect of construction let alone fire safety, although, strangely, the course didn?t concern itself with that aspect.
By the way, the practical fire risk assessment is, or at least was a number of years ago, a verstrange beast indeed.
