specified rooms and areas that

present a high fire risk to occupants.

Installer Scheme

All combustion processes generate CO

Natural Gas / LPGNatural Gas / LPG 20 20 –– 200 ppm200 ppm

Oil / LiquidOil / Liquid Up to 1,000ppmUp to 1,000ppm

Solid fuelSolid fuel Up to 20,000 ppmUp to 20,000 ppm

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

Boiler flue dislodged

in boiler room

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.

Product Standards for CO Alarms

Standards & Regulations

Choosing a CO alarm

Battery powered alarm• Lower purchase cost

• Easier to install

• Easier to remove

• Battery may have to be

replaced with some products

• Alarm has to be replaced after 7 years

• No interconnect with most products

• No signalling option with most products

Choosing a CO alarm

Mains powered alarm

• No batteries to replace

• Less likely to be removed

• No back-up if mains fails

• Higher purchase price

• Higher installation cost

• Alarm has to be replaced after 5/6 years

• No interconnect option

• No signalling option

Choosing a CO alarm

Mains powered with back-up

• Rechargeable back-up cells

• No batteries to replace

• Less likely to be removed

• Replace sensor after 5/6 years

• Hard wire and RF interconnect option

• Can be interconnected with smoke alarms

• Signalling via a relay option available

• Higher purchase price

• Same installation cost as mains only

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

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

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

interconnectedAlarms
