Choose the right CO alarm and be aware of false claims!

By | July 2, 2018

Following media reports this June about non-working imported carbon monoxide (CO) alarms sold on internet shopping sites, the Boat Safety Scheme (BSS) is cautioning boaters, that choosing the right CO alarm is an especially critical decision as boats can fill in minutes, sometimes seconds, with lethal levels of the highly toxic gas.

The BSS has teamed up with the CoGDEM (Council of Gas Detection & Environment Monitoring) to urge boaters to choose one from the list of CO alarms suitable for boats as recommended by the makers of independently certified products – the list can be found on the home page of the BSS website.

Incident reports collected by the BSS show that properly certified CO alarms have repeatedly protected skippers and crews from the hidden dangers of CO and ought to be regarded as part of the boat’s essential safety equipment.

The advice is to buy alarms that have been independently tested and certified by British Standards Institution (BSI), look for the Kitemark on the alarm or packaging or the Loss Prevention Certification Board, look for the LPCB Certification Mark.

CO alarms certified to BS EN 50291-2 are the best choice for boats, but if you have a CO alarm, BSI or LPCB certified to BS EN 50291, or 50291-1, CoGDEM’s advice is to keep it, test it routinely and when it needs replacing, choose a unit certified to BS EN 50291-2.

Look for the Kitemark
BSS Manager, Graham Watts says: “Reports of new alarms not working out of the box is very concerning so our advice to anyone worried that they have bought a non-functioning alarm for their boat, is to reassure themselves by looking for the Kitemark or LPCB Certification Mark.”

Leigh Greenham, Director and Administrator at CoGDEM adds: “We cannot stress enough that CO alarms are vital pieces of life saving equipment, but only independently tested and certified alarms should be trusted to do this most important of jobs.

“There’s no substitute for the good installation, regular maintenance and correct use of fuel burning appliances and engine systems, but if despite these steps, CO still occurs, boaters can have confidence in independently certified alarms protecting them and their fellow crew members.”

Silent Killer!
CO is produced when carbon-based appliance and engine fuels, such as gas, LPG, coal, wood, paraffin, oil, petrol and diesel don’t burn completely.

It cannot be seen, smelt, tasted, or felt, that’s why it’s known as the silent killer!

When you breathe in CO, it replaces the oxygen in your bloodstream, preventing essential supplies to your body tissues, heart, brain and other vital organs.

Survivors of severe CO poisoning may be left with severe long-term neurological problems, with disturbances in memory, language, cognition, mood and behaviour, as can some people exposed to lower, non-lethal concentrations of the toxic gas.

Alarms not only warn people about immediately dangerous amounts of CO, they can alert people to the presence of the lower, but still health-affecting, levels.

RYA Cruising Manager, Stuart Carruthers concludes: “An independently tested and certified CO Alarm that has been properly installed is a vital piece of safety equipment on any boat, but they should be treated as a last line of defence. It is vital that all boaters are also aware of the sources of CO and the signs and symptoms of CO poisoning so that they understand the dangers and take appropriate action.
