Posted By Caroline Cousins I am looking for a method for evaluating when to install a fire sprinkler system into a new build. There are obviously a number of factors that need to be taken into consideration including construction materials, final 'users', planned management of the building, location, history as well as cost etc. etc., but I need to be able to justify when we sometimes install and when we make a decision to put in AFD instead. Decisions of this nature tend to take ages, so if I can put something down that provides some element of justification one way or the other (probably with a bias towards sprinklers) it would significantly speed up the process. Has anyone any ideas on how to set this out?

Posted By Chris Pope Caroline Are there any circumstances where the Loss Prevention Council or indeed any other recognised body would maintain that AFD (i guess this means automatic fire detection) will get the emergency services there quicker and put a fire out earlier than sprinklers or other approved automatic extinguishing agent.

Posted By Frank Hallett Good evening Caroline. There really is no absolute answer to your question. Some will simply quote the LPC "Fire Offices" Rules, some will go for the varying BS ENs and quote them. Unfortunately, the intended size, shape, function, location proposed contents, proposed activities all need to be taken into account before deciding on any particular scheme of detection, warning and possibly automated response that includes some form of sprinkler system. Modern fire design will often try to build-in innovative answers to difficult design questions which will often lean towards some form of sprinklers. The answer is - it depends. Frank Hallett

Posted By David Kimmins Caroline There are two aspects to the question. 1) Lifesafety. 2) Business continuity. On the first point sprinklers do save lives. The NFPA in the US has no incident on record of two or more people dying in a fire with a properly designed, installed and maintained sprinkler system. (exceptions: explosion). and "Sprinklers reduce the rate of fire deaths by 1/2 to 2/3rds". The design & use of the building, the amount of people in it (& type), the amount of exits and good early warning fire detection are all factors to consider for installing sprinklers for life safety. 2) On business continuity it's quite simple, can your company exist and make money, supply it's customer etc.. make widgets whatever if that building/facility burnt down. There is a 3rd issue which may come into play depending on how many buildings you have, their value etc.. which is the cost of property insurance and business interuption insurance. I hope this was helpful David Kimmins

Posted By Barry Cooper Caroline What type of building and what operation is in it? Can I suggest you contact your insurance company for advice. Also I personnaly prefer AFD as this gives an early detection of fires, which from studies has proved to save lives. Usually sprinklers are installed to protect the building, as by the time sprinklers activate, people usually have evacuated. If the building is used as a warehouse for combustible materials then sprinklers would be advisable. The earlier responses are also good advice

Posted By AllanH Something to consider, is the building occupied 24/7 if so then a sprinkler system may be enough, if its not occupied 24/7 then you may need to consider linking the sprinkler system to an AFD system, what happens when the sprinkler system is down for maintenance what protection do you have are you still covered for insurance etc, what about burst pipes faulty sprinkler heads. If in any doubt contact your local fire safety dept. Just a thought!!
