Carbon Monoxide Alarms

Good news

All our properties with fossil fuel appliances will have a carbon monoxide alarm fitted by October 2022. This is a legal requirement and designed to keep you and your family safe from the danger of the presence of carbon monoxide in your home.

What is Carbon Monoxide (CO)?

Carbon Monoxide, also known as CO, is a very dangerous gas. It’s poisonous, but you can’t see it or smell it, and it is produced by appliances and vehicles burning fuels, such as coal, oil, natural/bottled gas, paraffin, wood, petrol, diesel, charcoal etc. People are killed each year, and many more suffer ill health from Carbon Monoxide (CO) poisoning.

Common household appliances that may use carbon-based fuels:

  • Boilers
  • Gas Fires
  • Central Heating
  • Water Heaters
  • Cookers – (please note it is the tenant responsibility to have gas cookers serviced.)
  • Open fires

High levels of CO in a house can be caused by:

  • Incorrectly or poorly installed fuel-burning appliances.
  • Blocked or cracked chimneys/flues.
  • Blocked vents or draught-proofing which makes areas with fuel burning appliances or fireplaces airtight.
  • Engines of cars, lawnmowers etc. left running in confined spaces.
  • Portable paraffin or gas heaters in badly ventilated rooms.

Having a Carbon Monoxide alarm is the most reliable way of checking there aren’t dangerous levels of this dangerous gas in your home.

What to do if your alarm sounds

If your alarm sounds, please take the following action:

  • Open the doors and windows to ventilate the area.
  • Turn off all fuel appliances where possible and stop using them.
  • Evacuate the property leaving the doors and windows open.
  • Get medical help immediately for anyone suffering the effects of Carbon

Monoxide poisoning, such as headaches and/or nausea, and advise that Carbon Monoxide poisoning is suspected.

  • Ring your gas – Cadent on 0800 111 99* or other fuel supplier on their emergency number. It’s a good idea to keep the number in a prominent place.
  • The alarm can be silenced by pushing the test/hush button (this will only work if the CO level is below 150ppm).
  • Do not re-enter the property until the alarm has stopped. If the alarm has been silenced by pressing the test/hush button, please wait at least 5 minutes so the Alarm can check that the CO has cleared).
  • Do not use the fuel appliances again until they have been checked by a
  • registered installer or equivalent expert.

When ventilation is provided by leaving the window and doors open, the CO build up may have dissipated by the time help arrives and the alarm may have stopped sounding. Although your problem may appear temporarily solved it is crucial that the source of the CO is determined, and appropriate repairs made.

Testing your detectors regularly

Just like smoke detectors, you’ll need to test your Carbon Monoxide alarm monthly to make sure it’s working properly – this is really important as they can save lives and help keep you and your family safe.

To test simply press the ‘test’ button and make sure you can hear the alarm sound loud and clear from every room in the house.
