From the BBC:
London’s fire commissioner says the Grenfell Tower blaze must be a “turning point”, calling for sprinklers in all high-rise council flats.
Dany Cotton, commissioner of the London Fire Brigade, said: “I think Grenfell should be a turning point.
“I support retrofitting – for me where you can save one life then it’s worth doing.
“This can’t be optional, it can’t be a nice to have, this is something that must happen.
“If that isn’t one of the recommendations (of the Grenfell Tower inquiry) then I will be so very disappointed.”
Firstly a little on the background of Dany Cotton:
Since 2017, she has served as the Commissioner of the London Fire Brigade and is the first woman to hold this position. She had previously been the Director of Safety and Assurance at the London Fire Brigade. In 2004 Cotton became the first woman to be awarded the Queen’s Fire Service Medal. She is the National Chair of Networking Women in the Fire Service.
Aged 19, she had been a full fire-fighter for just three months when she attended the Clapham Junction rail crash. In 2007, she was assigned the post of Area Commander, becoming the highest-ranking woman in the British Fire Service.
Her professional biography seems to be a lot more about being a woman than a firefighter. But let’s look at her remarks.
Retrofitting sprinklers into an existing building will be extortionately expensive:
Croydon Council, in south London, has taken the decision to retrofit sprinklers in its 25 high-rise blocks at a cost of £10m.
I bet that figure will triple. Of course, somebody who has only every worked for a taxpayer-funded organisation like Cotton wouldn’t care too much about what things cost. Look at this statement again:
for me where you can save one life then it’s worth doing.
For a public servant in charge of safety to come out with this is rather illuminating, as it appears she has no idea about how resources are applied to minimise risk. When it comes to safety, you want to spend the money in the areas where it will have the most impact. For example, do you spend £10m on sprinkler systems if the same money spent on networked fire alarms and better fire doors would save more lives? This is something a risk assessment and cost benefit analysis would tell us, and this is what should have been done. The fact that we have the head of the London Fire Brigade saying sprinklers should be retrofitted regardless of cost and their effectiveness suggests that it hasn’t. Then again, nobody seems even in the slightest bit interested in what caused the initial fire, so perhaps we ought not be surprised.
The money from these sprinklers has to come from somewhere, and this will mean cuts to other services or an increase in rents. If the latter, it will push those at the margins into cheaper, less safe accommodation. The video here is not an outtake from The Lord of the Rings but an interview with a spectacularly smug and idiotic Welsh MP talking about Wales being the first country ever to make sprinklers mandatory in all new homes:
I hope they will just look and listen, and I think this idea about over-burdening and over-regulating has proved that we do have to have those regulations. You know, sprinklers have been around since 1886 and the building industry haven’t used them successfully so, you know, if you’re not going to use them in goodwill, then as we have done in Wales, we’ll mandate for you to use them to keep people safe.
Aside from the first sentence being gibberish, at no point does it occur to her that there are good reasons why not a single country in the world has insisted sprinklers are installed in ordinary homes since their alleged invention in 1886. But apparently the Welsh know better and have made it compulsory, and now want to foist this idiocy on the rest of the country.
All this will do is push up the cost of housing, which in the UK is the last thing you want to do. Again, this will simply push those at the margins into cheaper, less safe accommodation. And presumably all homeowners and tenants will know exactly how these systems work and are maintained. I know I wouldn’t.
There’s also the issue of how effective sprinklers are in houses and flats. My understanding, at least from how they’re deployed on oil and gas installations, is they exist to keep surfaces cool and stop fires spreading as opposed to putting fires out. From what I can work out, the fire protection philosophy in buildings is to contain the fire using fire doors, use sprinklers to stop it spreading and keep the escape ways clear, giving you time to evacuate. The fire brigade then come in and put the fire out. In other words, they make sense in places with a proper evacuation plan but not so much in stand-alone private residences.
Interestingly, I’m sat in a 40-storey tower built between 1982-85 which has no sprinkler system. They have fire hoses on each floor but (and I’ve just checked) no sprinklers in the offices, corridors, or stairwells. Is the building unsafe? Probably not. Every door is a fire door, they have a decent alarm system and in the event it goes off everyone evacuates. I suspect a more modern tower would have a sprinkler system in, but I am reasonably sure its purpose would not be to put out an actual fire.
Would sprinkler systems help in a tower like Grenfell? Probably. Would they make much difference in the absence of fire doors and an evacuation procedure? Probably not. They might keep the stairwell clear, but if they’re installed in the apartments themselves you can expect a lot of spurious discharges as people set them off by mistake or maliciously, which would upset those in the flats below. Are they worth the money? In a new-build block, probably. But to insist they’re retrofitted regardless of cost or the lives they’ll save is madness, as is mandating their installation in new-build houses. The money would be far better spent on other fire-safety measures.
I think people have seized upon sprinklers as the solution of the day without really knowing what they’re for or how they work, let alone what they cost. That the head of the London Fire Brigade doesn’t seem to know any better ought to shock, but actually it doesn’t, not at all. This is the new normal. At least she’s got a few medals.
