Tragic Incident
• Boiler slow to fire-up resulting in a build up of gas in firebox.
• Boiler eventually ignited, a small explosion caused the flue
to become displaced.
• Exhaust gases escaped into the boiler room
• Fumes leaked into 2 bedrooms above
• 1 man died and there was also a near miss.
• A CO alarm would almost certainly have saved them.
Bedroom 1
1 man died due to
CO poisoning
Bedroom 2
1 woman poisoned

Tragic Incident
• A flue leading from a boiler had been fixed just below the
bathroom window of a seaside hotel bedroom.
• The window had been screwed down but was later
undone – fumes entered the bedroom
• 1 man died from CO poisoning
• Flue and terminal were installed in the wrong place and in
the wrong way.
• Two employees of the installer company were charged
with manslaughter and received fines.
• Statements from family included ...
"We hope everyone who reads this will buy a carbon
monoxide alarm and pass the message on."

A near miss
• Lady was complaining of flu-like symptoms
• CO Alarm was fitted and it did respond.
• Gas engineer could not find a problem – claimed
CO Alarm was faulty
• New digital alarm showed high levels of CO
• Exhaust gases were coming from the flat below
• A Near miss showing the value of fitting CO alarms

Flues in voids – existing installations
• Gas Safe Technical Bulletin 008
Edition 3 issued April 2013
• Inspection hatches must be
fitted, OR
• A void monitoring system should
be installed
• How many will be?

Flues in voids – an alternative
• Install a CO alarm in all habitable
rooms that the flue passes through

Gas Cookers
• Owned by the tenant –rarely serviced?
• Can emit significant amounts of CO – 400ppm
not uncommon!
• Low level CO poisoning can
cause long-term health
problems
• Can this be ignored as
being outside of your responsibility?

Corgi Report 2009
• ‘Just over 72% of installers said they have discovered a CO leak on a customer’s appliance’
• ‘Nearly 50% of CORGI registered installers say they recommend that their customers install an audible CO alarm’
• ‘through increased awareness of CO, it is hoped that public knowledge about the importance of installing an audible CO alarm will increase’.

Gas Safe Register recommends the use of audible carbon
monoxide alarms marked with British Standard EN 50291. It
should also have a British or European approval mark, such as
a Kitemark.
What the Regulatory bodies say
England & Wales Building Regulations requires a CO alarm to
be installed when a new solid fuel appliance is installed or
when an existing one is replaced
Northern Ireland Building Regulations requires the
installation of a CO alarm when any fuel burning
appliance is installed – new and existing installations
Scotland Building Regulations requires the installation of
a CO alarm when any fuel burning appliance is
installed – new and existing installations

Quote from Baxi website
‘For you and your family's safety, it is advisable to fit a carbon
monoxide alarm in each room in your home that has a gas
appliance’.
Response to e-mail enquiry to Worcester Bosch
We don't have a specific company stance on it [installing CO
alarms] - we would always refer customers to Gas Safe
Register's guidelines.
Quote from COCAA section of Vaillant website
Fit an audible Carbon Monoxide alarm. CO alarms need to
meet European safety standards and must be audible.

Where to site CO alarms• In all rooms where there is an appliance
• 1st Priority – open-flued or flue-less appliances
• 2nd Priority – where people spend most time
• 3rd Priority – where appliance is most used
Open–flued
appliance
![Page 36: Fire Standards & Regulations Are you confused? · 2013-11-13 · Fire Alarm Systems There is no risk low enough to negate the need for some form of system •Single household up to](https://reader034.fdocuments.in/reader034/viewer/2022050403/5f80e25d789b2777f344eabd/html5/thumbnails/36.jpg)
Siting CO Alarms
• BS EN 50292 allows wall or ceiling mounting
• BRE GBG 30 recommendations based on trial results...
• Ideally, site on the ceiling at least 300mm from wall or
other obstruction - the easiest siting position
• Site 1 - 3m from the appliance
Ceiling mounted Recommended Siting position
![Page 37: Fire Standards & Regulations Are you confused? · 2013-11-13 · Fire Alarm Systems There is no risk low enough to negate the need for some form of system •Single household up to](https://reader034.fdocuments.in/reader034/viewer/2022050403/5f80e25d789b2777f344eabd/html5/thumbnails/37.jpg)
Wall Mounting
• If it must be on the wall:
a). High as possible – 150mm from ceiling
b). Higher than doors or windows
• Between 1 – 3m from source of CO.
• Not easy to meet these restrictions

Siting CO Alarms
• Where the appliance is in a confined
space e.g a boiler room

Interconnecting alarms
• If only one CO alarm is installed audibility
could be a problem
• Interconnection with smoke alarms can
overcome this
