HEATCARBONMONOXIDESMOKEEN50291: 2001SMARTINTERCONNECT))Kidde FyrneticsKidde Fyrnetics manufactures 24 million CO, smoke and heatalarms every year and has unrivalled expertise and commitment toongoing research and development – with the resources to matchas part of the $37 billion United Technologies (UTC) group. Ouralarms are all Kitemarked and made in our ISO 9001 and 14001certified factories. We have unrivalled expertise in CO detection,particularly in the USA where this problem has now been addressedby legislation.The launch of our new range of hardwiredcarbon monoxide alarmsspecifically for the UK market followsextensive development and testing.

CO and human healthEffects of CO concentration over timedemonstrating why CO alarms need to monitor bothconcentration and durationThe graph shows that a low level ofCO exposure over several hours isjust as lethal as a short-term highexposure level.According to the Health and Safety Executive, carbon monoxide(CO) poisoning causes an estimated 50 deaths and 200 seriousinjuries annually in Britain. Other organisations have recordedhigher fatality and injury levels and all these figures reflect justwhat we know about: CO poisoning is certainly underdiagnosedby doctors and often not recognised by coroners, asit simulates other conditions.CO is odourless and colourless. It bonds with haemoglobin inthe blood to gradually replace essential oxygen, preventing theuptake of oxygen into the blood, resulting in headaches,nausea, unconsciousness – and finally death. While exposure tohigh concentrations leads to collapse, long-term exposure tolower concentrations can result in symptoms similar to flu orfood poisoning. As the chart shows, lower level exposure overa longer period can prove fatal just as higher level, short-termdoses. Surviving victims of CO poisoning may well be leftpermanently unwell and disabled through neurologicaldamage.Key50% COhb Death45% Coma/brain damage40% collapse35% vomiting30% drowsiness25% Nausea+headache20% headache15% mild headache10% none5% noneCO alarms – standardssiting CO alarmsThe current standard for carbon monoxide alarms, BS7860, willcease to apply in April 2006 being replaced by EuropeanStandard BS EN 50291:2001 – a much tougher standarddesigned to increase safety and improve product integrity.This incorporates aspects of the US standard UL2034 andrequires CO alarms to trigger at lower concentrations thanpreviously. While all newly designed CO alarms must comply,existing alarms complying only with the old BS are stillavailable. Another newstandard, BS EN 50292,will apply to selection,installation, use andmaintenance – includingsiting.The number and locations of CO alarms will depend upon thedwelling layout. It is essential that carbon monoxide reaches thealarm from the source to trigger it and the alarm sounder must becapable of waking sleeping occupants. To achieve this with just oneunit is difficult and a network of interlinked alarms – for examplewith the Kidde Fyrnetics Smart Interconnect feature - is preferable,with one alarm in each sleeping area and at least one on every level.CO alarms should never be installed in bathrooms, shower rooms,boiler rooms or garages.The optimum positioning of a CO alarm within a room is discussedin the Kidde Fyrnetics CO alarm installation manuals and the latestinstallation standard, BS EN50292.
