Faulty CO alarms

Following media reports about non-working, imported CO alarms sold on internet shopping sites, the BSS cautioned boaters that choosing the right CO alarm is an especially critical decision, as boats can fill within minutes, sometimes seconds, with lethal levels of the highly toxic gas. The BSS and the Council of Gas Detection and Environment Monitoring (CoGDEM) urge boaters to choose an alarm that has been independently tested and certified by the British Standards Institution (BSI). Look for the Kitemark on the alarm or packaging, or look for the Loss Prevention Certification Board (LPCB) Certification Mark. CO alarms certified to BS EN 50291-2 are the best choice for boats, but if you already have a CO alarm that is certified to BS EN 50291, or 50291-1, CoGDEM’s advice is to keep it, test it regularly and choose a unit certified to BS EN 50291-2 when it needs replacing. Some alarms are not recommended for use on boats and a list of recommended alarms that are suitable is available at www.boatsafetyscheme.org/media/294453/boat-co-alarms-may-18.pdf
