Ian
You have misunderstood my comments and I resent your patronising reply. By all means debate your point, but please don't judge people, or their levels of competence.
Firstly would you like to tell me which authority I work for seeing as you seem to know so much about me?
To my knowledge no fire authority discourages the installation of sprinkler systems in new builds, also they try to push for sprinklers in existing buildings wherever possible too, sometimes they are unable to enforce it however.
Secondly yes I do know about sprinklers thank you, Im not sure why you feel I don't - strangely you actually confirm what I said originally about perceptions of cost that the layperson has about sprinkler systems - so not sure what you were trying to prove there.
I agree with you about people having choice of open plan living. Great!.
But alas you miss the point we are making relating to the real world where human behaviour issues mean that the sprinkler system won't be maintained properly by the residents for the reasons I and other people on this forum have eluded to.
Such precautions should be maintained. Fire alarms should be maintained, emergency lighting systems have to be maintained, my car's brakes have to be maintained... why? not simply because the law says so , but because regular maintenance ensure the device concerned will work when required. Unless you are suggesting we don't need to maintain sprinklers?
So some people remove doors? or dont reapir them as you mention. Yes correct. Some do, others dont - most people however do repair damaged doors for privacy or security reasons as I said. Doors are more obvious than the components of a sprinkler system, so when something is wrong with the door they are more likely to notice it.
The point I make is that without doors smoke would be allowed to perculate throughout the building in the event of fire
I think I''ll deal with the issue of smoke spread in the incipient stages of fire thank you Ian:-
If (to quote your scenario) we have smoke detection, and as you said the resident is awake why cant they put the fire out? Well there is no reason why they can't put the fire out. But they could do that regardless of whether sprinklers are fitted or not, so again not sure of your argument there.
But what about if those persons were asleep?
Furthermore not sure where you are coming from asking about "how many deaths I have investigated where the fire was slow growing and smouldered, producing cool smoke and the person aware of the fire"
The answer is none for obvious reasons. I have witnessed slow growing smouldering fires however where alot of smoke was generated in a short space of time and been able to permiate through the rest of the property.
Sprinklers do not initially stop smoke and thats exactly why I bring up this point.
Smoke is the killer not flame. You still need doors along with sprinkler systems (note i DID NOT say fire doors) Sprinklers do not negate the need for doors Ian.
YOu are quite right that people do prop open doors and that aids smoke travel, but I ask you again you try saying to a landlord of a HMO "fit a sprinkler system" and see what reply you get. Also tell me how sprinklers stop propped door situations!.
