So, we don't (and shouldn't) 'hug' the codes, but we must measure our assessment of risk against them.
Hi Fishy
I agree with you but am not sure what this means in practical terms. My experience of several brigades leads me to think that
for example in a small chocolate box B&B,
-irrespective of size and layout and travel distance
-irrespective of the assessment of risk of fire occurring
-irrespective of the standard of management
-irrespective of the numbers and profile of guests
we must have fire doors to each room opening onto the escape routes and we must take the guides definition of an LD3 system with a detector in every room leading onto an escape route. (which differs from the BS5839 definition?)
It seems to me that irrespective of the findings of the risk assessments, many brigades will not ever relax these provisions as illustrated on page 97 of the guide. Even for one letting bedroom on the first floor of a traditional two storey dwelling house with an enclosed staircase . The guidance says that the arrangement shown in the diagram on page 97 is suitable for buildings accommodating up to 60 persons per floor. Clearly there must be a very significant difference in risk between a building capable of housing 60 person per floor and one housing a handful of persons- even taking the basic liklihood and consequences approach to risk assessment.
This attitiude to enforcements limits scope for finding a proportionate compromise, ie to fully take into account the size and nature of each business; to install "such general fire precautions as may be reasonably required in the circumstances of the case" (Article 8.1.b). or any relaxations of page 97 fire safetyarrangements that may be "appropriate, having regard to the size of the undertaking and the nature of its activities" (Article 11.1).
It has been suggested to me that the only alternative to installing fire doors may be sprinklers.
