Sprinklers in Schools
« on: November 19, 2004, 08:28:46 AM »
DfES are planning to consult shortly on a fire safety guide (BB100) for schools. The plan is for this to serve in place of AD B for the Building Regs and also to give advice on property protection issues.

see  http://www.fire.org.uk/BBC_News/News2004/November/9hansard.htm

At the same time (coincidence?) The FBU and Teachers Unions are pushing to get sprinklers fitted in more schools.

One of the things that often gets raised is the risk of malicious operation of the sprinkler heads (I would have done it when I was a kid).

I know that quite a few schools are now being fitted with sprinklers so, without getting drawn into the broader issues - which we have debated in the past - does anybody have any experience of this or what if anything is being done to prevent it?

Are people using specialist sprinkler heads?

Are today’s children much better behaved than me?

I speak as someone who works for the company who insures about 75% of the schools in the UK.  We are aware of 71 sprinklered schools and about 50 being fitted.  To our knowledge (and we continualy ask and are in close contact with BASA on this) there has never been a malicious activation.

This is mainly because recessed heads are so hard to spot.

Bear in mind that usualy the insurer would pay for the water damage from £0 up anyway as they are usualy so keen to have sprinklers in.

The issue of school fires cost £96.6m in 2002 and £78m in 2003.  It's a real serious issue.

Chirs

You suggested that recessed heads are hard to spot, do you mean concealed heads with a cover plate or recessed heads that sit inside an escutcheon but are themselves still visible?

I'm not being pedantic for the sake of it, I just want to be sure on the type of head that is in use.

Concealed heads with cover plate that drops off at 58 degrees, sorry for the confusion.

Thanks for pointing out the mistake, it is important, the last thing we want is schools not putting them in because they think they will be vandalised.

If it were not for the various myths that exist:
Vandalism problems in schools
Misconceptions about water damage
Misconceptions about chances of product failure
Misconceptions about all heads going off at once (only the ones above fire go off)

I am sure we would see many more.

In 60% of fires, 4 or less heads activate.
In 99% of fires, the fire is extinguished by sprinkers alone.

(Source: European statistics over 10 year period www.basa.org.uk)

Like I say, we have yet to have one set in a school by a vandal.

(Source: Zurich Municipal)

Accidental discharge of water due to manufacturing defects is 1 in 14,000,000 (per year of service)

Thanks for that.

There must be some vandalism in schools - isn't that why they keep burning down?

We'll have wait and see what BB100 has to say.

There is indeed very serious vandalism in most UK schools, but not to sprinkler systems.

90% of large fires at schools are maliciously set.

Sorry about the slightly flippant comment. This BB brings out the worst in me.

Does this mean that they are regretting the departure of BB7? I have heard this view expressed by architects and personally found it easier to consult BB7 than extricating the relevant parts for schools from the approved documents.

Sprinklers seem to be generally seen as a property protection rather than life protection measure and whenever suggested, in my experience, the client has preferred to go with the current 'industry practice' of not having them (and saving the cost). I suspect that there is insufficient direct relationship between insurance premiums and those controlling school spending budgets for sprinklers to be seen as a cost-saving measure. A stronger stand on this by the DfES might, however, have the desired effect.

Proper risk management would assess all the savings that a sprinkler system brings, not just the insurance premium discounts.  Insurance doesn't pay for many of the aspects of the loss including:
The deductible (excess) perhaps £100,000 - £250,000
Business Interuption costs (unless insured)
Transporting kids to alternative locations for perhaps 3 years
Hire of temporary accomodation for rebuild period
Loss of community facilities, scout groups use, local training facility, sports facilities - schools are moving towards community use
Environmental damage of fire, smoke in environment, polluted run off water
Environmental damage of needing to use finite resources to re build
Environmental damage to trannsport good used to build school
Staff stress, demotivation
Pupil stress and demotivation
Lost work, coursework
Loss of personal effects, pupils and teachers
Loss of teaching aids, most of which take decades to buid up.
Injury and loss of life (money cannot fix these things)

In addition to the insurance premium savings (which could is significant) and typically with withdrawal of the deductible (excess) for fire, there are plenty other benefits:
Inceased architectural freedom in terms of compartment sizes and building components used
Knolwedge that my list above won't happen

Proper risk management would cost benefit all these costs, although the insurance premium saving, on an individual premises (problem being most schools not insured individually) would cover the costs, just depends how long it will take.

Sorry Ken, just to answer your other points.

DB7 - can't comment, but it is the architects jobs to be able to understand the legislation in that regard.  Free advise is available from school insurers who will work with architects given the slightest opportunity.

Some local authorities and PFI contractors will only build sprinkler protected schools in future.  It tends to be the "Risk Management and Insurance" Departments who make such decisions, after having costed out the benefits.  These local authorities are in a minority, in my opinion, due to widespread misconceptions (listed above) about sprinklers and a lack of appreciation of the benfits of them and a lack of appreciation of the full cost of a major fire.

Like I have said before, school are unique in terms of the frequency and cost of arson attacks in them.

Thanks, Chris.

I agree with the points you make - of course! The problem seems to have been that the risk assessment factors to which you refer have not been addressed in this way with regard to sprinklers in schools. The assessments have generally been made at school level by persons with limited financial control and with academic achievement as their primary goal.

When I was with an education authority (some years ago) the purse strings for school building works were held tightly at the centre and schools with leaking roofs, unsafe electrics, asbestos-ridden buildings, etc, etc were competing with each other for the limited sum allocated by the politicians to the department. Sprinklers had no chance and if there was fire damage, insurance was there to cover anything beyond the excess. This would then become essential expenditure - at the expense of other school needs. The insurance officer was someone in another department in another building dealing with the multitude of claims and issues of an entire council and I doubt if school sprinklers featured much on his agenda and, anyway, none of the other authorities around were putting sprinklers in their schools. Hopefully the 'picture' has been improving since then but the sprinklers have still not arrived.  In recent years, I have been involved with the design and management of a number of school buildings and, whilst AFD has been accepted throughout, architects and clients have always stopped short of having sprinklers other than in perceived high-risk areas with cost being given as the reason together with the fact that they are not specifically required by the DfES, HSE, fire authority, etc. Additionally the insurers will not offer any discount for having them!  I hope you will appreciate, therefore, my interest in seeing something from the DfES to the effect that all new school buildings must have an adequate sprinkler system and that all existing buildings should have a plan for the progressive introduction of sprinklers over a stated period of time (eg as per the required access plans following the introduction of the DDA)

The earlier document to which I referred was BB7 (Building Bulletin 7: Fire and the Design of Educational Buildings) which was updated over the years and provided an easy access document for designing and altering schools - with lots of diagrams and tables. The transfer to Building Regs submerged the information with that for all other buildings and lost some clarity along the way (such as specific maximum direct distances).
