Mandatory CO alarms introduced from 1st April 2019

A newer one from the manufacturers website, which now shows the CO-9X-10 as suitable for boats. The C0-9D is still shown as only suitable for caravans and motorhomes.

Best guidance I can think of is to use BSS and sales web-sites to make an initial choice, then check the Kitemark Certificate to make sure the advice is sound and up-to-date.
Then check the printed copy in the box after/at purchase.
 
I've spoken to Fire Angel and they say the only reason the C0-9D is not recommended for boats is because the LED display is not fully sealed and being in a damp marine environment could cause an issue with the display. As far as the actual Co alarm is concerned it will work exactly the same as the other models that are recommended for boat use.
 
A couple of other thoughts. if you are away from the boat for while check if the CO/CO2 alarms work, also be aware of the symptoms:
Signs and symptoms of carbon monoxide poisoning may include:
Dull headache.
Weakness.
Dizziness.
Nausea or vomiting.
Shortness of breath.
Confusion.
Blurred vision.
Loss of consciousness.

I also noticed a question about where alarms should be placed in the engine room.
 
I doubt whether raw sewage is being dumped into a tidal river as this is illegal and has been for some time. It is also vigorously enforced by the EA. There may be a storm overflow which has received primary treatment but only discharges during storm conditions.

Doubt anything will change below Allington Lock unless the marina/boat club/yard mandates you must have one.
With all the raw sewage being dumped into the river from St Werburgh "Marina "at Hoo, Peel Ports appear to have no effective juristiction over safety in the tidal Mudway at all ?

Has anyone actually ever seen, or fitted, a CO2 alarm?

Is such a thing even available for use on a boat?

Google will find a small number. Most seem to be mains powered but 12 volt ones do exist

Suitability for boats not specified

The post referred to pollution from a marina, so I assume is about boat toilets rather than shore sewers.

I think CO2 in a large quantity it cause cause serious harm

Carbon dioxide is a physiologically important gas, produced by the body as a result of cellular metabolism. It is widely used in the food industry in the carbonation of beverages, in fire extinguishers as an 'inerting' agent and in the chemical industry. Its main mode of action is as an asphyxiant, although it also exerts toxic effects at cellular level. At low concentrations, gaseous carbon dioxide appears to have little toxicological effect. At higher concentrations it leads to an increased respiratory rate, tachycardia, cardiac arrhythmias and impaired consciousness. Concentrations >10% may cause convulsions, coma and death. Solid carbon dioxide may cause burns following direct contact. If it is warmed rapidly, large amounts of carbon dioxide are generated, which can be dangerous, particularly within confined areas. The management of carbon dioxide poisoning requires the immediate removal of the casualty from the toxic environment, the administration of oxygen and appropriate supportive care. In severe cases, assisted ventilation may be required. Dry ice burns are treated similarly to other cryogenic burns, requiring thawing of the tissue and suitable analgesia. Healing may be delayed and surgical intervention may be required in severe cases.

Of course, we are always hearing cases of yachts with leaky exhausts killing people onboard from the Co2 from the engines.

Chances are, you'd die of old age first.

Yep absolutely , just pointing out that CO2 is toxic in high quantities , but if your boat is pumping out that much CO2 Via the exhaust and you dont notice all that smoke ,well there is no point in having an alarm :D

When you hold your breath (voluntarily or otherwise) it's the elevated CO2 levels, rather than a shortage of oxygen, which give you that pressing urge to breath. On the whole, this is a good thing.

Elevated levels also seriously impair judgement. Computer keyboards are clearly strong emitters of the stuff...

A mother and her 10-year-old daughter died after inhaling carbon monoxide fumes as they slept on a moored motor cruiser on Lake Windermere, marine accident investigators have confirmed.
Fumes from a generator, whose improvised exhaust and silencer system had become detached, had spread into the cabin where Kelly Webster, 36, and daughter Laura Thornton, who were on an Easter boating holiday, were asleep. The boat belonged to Matthew Eteson, who was Webster's partner, 39, who was on board but survived the incident.
"The boat's carbon monoxide sensor system did not alarm because it was not connected to a power supply," said an interim report by the Marine Accident Investigation Branch (MAIB).'

I seem to remember the man involved was later found guilty of manslaughter
