Nearlythere .... I disagree with two of your last statements at the end of your post.
There are times when we have to stay outside and adopt defensive techniques, although we will not stand and do nothing, we will do something, such as get jets to work, arrange hydrant feeds etc etc. An example of this tactic would be a large retail unit such as B & Q Warehouse ..... half brick, half lightweight cladding around a steel frame. Rapid fire growth and spread means these building collapse quickly, so to commit personnel into them is, in my opinion not an option.
Procedures and policies are there to provide a framework for dealing with incidents, the Standard Operating Procedure. They are not a stick to be beaten with, they are there to be adhered to and as a manager, if I have operated outside the procedure and something goes wrong, I would expect to take the full rap for it ....... I would also expect a visit from the HSE!
