BS in prisons ?

[Mr. P]

DtD, Thanks for that. I am sure that has clarified it for many of us (hope it was not just me guys!).

Spot on Dave. Hence the use in cells. Prisoners are allowed to smoke and this would cause problems to a typical smoke detector. Back to the original question, prisons must now conform to the RR (FS) O where as in the past they were exempt but came under the 'crown inspectorate-fire'. So if they are now under the RR (FS) O then the systems employed have to be up to date and suitable and sufficient.

Once again with the Scottish perspective, like the RR(FS)O the Fire (Scotland) Act and the Fire Safety (Scotland) Regulations 'shall bind the Crown'.
Enforcement in Scotland in Crown premises is by Enforcement Officers from HM Inspectorate of Scottish Fire & Rescue Services. Enforcement is done by Notices, Alterations Notices and reference to the Court of Session (in the final instances).
With regard to standards of cover the automatic fire detection systems are equivalent (in Scottish Prisons) to a M/L1 coverage, every cell, every room, every space bigger than a biscuit tin. Emergency lighting is to BS 5266, signage follow the BS 5499 series etc. etc.
As for smoking, Prisoners are permitted to smoke in their cells (considered on legal advice to be their domicile) but is prohibited everywhere else and for everyone else.
For security / operational reasons some fire safety provisons have to be 'restricted', e.g. access to extinguishers, hosereels and even (occasionally) manual operating points for the fire alarm system.
Evacuation drills involving prisoners need careful consideration as do trainng exercise for the local F&RS ops crews.
Happy to discuss further by direct e-mail if fire safety in Prisons is of interest.

Not sure why CO dets would be considered as boiler, plant etc was remote. Did not see anything that would contribute to a CO risk either.

Having read a number of threads recently including this one there does seem to be some confusion on CO fire detection and Carbon Monoxide detectors.

So here goes –

Carbon Monoxide is invisible odourless and tasteless gas produced by incomplete combustion e.g. faulty household appliances such as gas and oil boilers, water heaters or ovens. They usually sound a warning if the levels reach 100ppm over 90 minutes, 200ppm over 35 minutes or 400ppm over 15 minutes. Two basic types of detectors

1.   Biometric – sticky pads that change colour.

2.   Gel cell detectors – photoelectric eye that senses a colour changes in a chemically treated disk of gel, this mimics the body’s response to CO absorption usually battery or mains powered.

These should not be confused with CO detectors used to detect fire.  

These electronic detectors protect against fire by sensing low amounts of CO in the air normally operate at 30-50ppm. There isn’t a relevant BS or European standard but should operate within 60 seconds of the concentration reaching 60ppm    

Effective for deep seated smouldering fires.

Do not pick up flaming fires or fires not involving carbon.

Good for hotels rooms and residential care bedroom but not recommended for escape routes.

I thought 'CO' is just the chemical representation of 'Carbone Monoxide', the only thing there are different versions to suite different applications? But it still CO detector = Carbone Monoxide detector isn't it?

Correct, CO = Carbon Monixide, but there are two different reasons to detect CO and two different types of items.

1 - people use in their home so that if their gas fired boiler or fire is not working properly CO will be detected before they are killed by it (I have one of these in my house, cost about £15).
2 - part of a fire detection and alarm system.  Purpose - to detect a fire.
