Colin, I have looked at your book and I found it full of good advice and information. However I did not find a clear, concise list of the principles that I seek. The reason that I am going on about this is that I think that they would be a benefit for us. If we were able to clearly identify these principles we could, for example, apply them to the guidance coming from ODPM. The guidance could be judged in a more objective way and hopefully a better product would be produced.
But we need to start on solid uncontroversial ground. In spite of the fact that most of this site is full of argument I think that there are core principles that we can all agree with.
The principles that I have listed above (Logical, etc) do not give direct fire safety advice. But their application will assist the production of effective fire safety measures. I think that they are applicable to the fire engineer or the "competent person."
