In this three-minute read, we examine the dangers posed by carbon monoxide.

We recently read a statistic about private landlords that left us scratching our heads.

A whopping 56% of private renters say they live in a property that doesn’t have a carbon monoxide alarm*.

Can such a high percentage of landlords really be ignoring safety advice and flouting regulations on carbon monoxide alarms?

By law, landlords must have:

  • At least one smoke alarm installed on every storey of their rental property which is used as living accommodation, and
  • a carbon monoxide alarm in any room used as living accommodation where solid fuel is used – after that, the landlord must make sure the alarms are in working order at the start of each new tenancy.

Many experts also recommend having an alarm near a gas appliance (such as a boiler), although this is not a legal requirement.

These rules are there for a good reason – carbon monoxide poisoning can cause severe illness and even death. There’s no excuse for complacency.

How is it made?

Carbon monoxide is a by-product of burning fossil fuels. When fuels like gas, oil, charcoal, wood, or coal fail to burn properly (a process called incomplete combustion, caused by a lack of oxygen), carbon monoxide is produced.

Exposure to it is hazardous to humans and animals.

Detecting it

You can’t see, smell or taste it; hence its nickname, the Silent Killer. To keep safe, you need to ensure carbon monoxide alarms and fuel-burning appliances are in good working order.

Good ventilation is crucial, too. Blocked flues and chimneys are problematic, as are poorly fitted flues. 

Other warning signs include: 

  • Black or brown stain marks around heaters and fireplaces. 
  • Pilot lights on gas appliances that extinguish regularly or burn yellow (they should burn blue).
  • Flames that burn yellow or orange.
  • Excessive condensation in a room where there is a device that burns fossil fuels.
  • Excessive soot.

Symptoms

Signs of carbon monoxide exposure include vertigo, tiredness, nausea, headaches, chest pains, and blurred vision. The affected person may slip into a coma and then die. The NHS says 60 people die from carbon monoxide exposure every year.

Keeping your tenants and property safe

Landlords should:

  • Brush up on the regulations and install carbon monoxide alarms where required.
  • Ensure working fireplaces are serviced and swept by a competent person.
  • Have gas appliances regularly serviced by a qualified engineer.
  • Check any carbon monoxide alarms in the property are working when the tenant moves in (note this in the check-in inventory). 
  • Ask tenants to test carbon monoxide alarms regularly.
  • Test carbon monoxide alarms during mid-tenancy inspections. 
  • Endeavour to avoid cowboy builders who could bodge boiler and flue installations.
