See No Evil? Smell No Evil? Can We COpe? Understanding the Dangers of Carbon Monoxide Exposure
Carbon monoxide (CO) is known as the “silent killer” for a reason. It’s colourless, odourless, and tasteless, making it virtually undetectable without the right equipment. In our homes and businesses, CO exposure can pose a serious threat to health and safety.
But what exactly is CO, how can we recognise a leak, and what should we do if we suspect poisoning? Most importantly, how can we protect ourselves and our loved ones from this hidden danger? At Smart Heating EA Ltd, we’re committed to keeping your indoor work and home environment safe and comfortable.
What is Carbon Monoxide and Why is it Dangerous?
Carbon monoxide is a poisonous gas produced by the incomplete combustion of fossil fuels, including gas, oil, wood, and coal. In homes and businesses, this can occur in:
Gas boilers
Furnaces
Fireplaces
Gas stoves and ovens
Portable generators
When inhaled, CO prevents oxygen from binding to haemoglobin in the blood, effectively starving your body of the oxygen it needs to function. Prolonged exposure can lead to severe health issues, including brain damage or even death.
How to Recognise a Carbon Monoxide Leak
Since CO is invisible and odourless, recognising a leak isn’t straightforward. However, there are some warning signs to watch out for:
Yellow or flickering flame in gas appliances (a blue flame is normal)
Sooty or scorched marks around appliances
Increased condensation on windows and walls near appliances
Pilot lights frequently blowing out
Unusual smells only noticeable when appliances are on (not the smell of CO itself, but other fumes may accompany a leak)
Symptoms of Carbon Monoxide Poisoning
CO poisoning can easily be mistaken for other illnesses, such as the flu. If you or others experience the following symptoms, particularly when indoors and they improve when outside, CO could be the culprit:
Headaches
Dizziness
Nausea and vomiting
Shortness of breath
Confusion or disorientation
Loss of consciousness
What to Do if You Suspect CO Poisoning
If you suspect a CO leak or experience symptoms of poisoning, take the following steps immediately:
Leave the Premises
Get everyone outside into fresh air.Call Emergency Services
Dial 999 or your local emergency number.Do Not Re-Enter
Stay outside until emergency personnel declare it safe.Seek Medical Attention
Even if symptoms are mild, get checked by a healthcare professional.
Preventing CO Exposure in Businesses and Homes
The good news is that CO poisoning is entirely preventable with the right precautions:
Install CO Detectors
Place them in sleeping areas and near fuel-burning appliances.
Service Appliances Regularly
Make sure boilers, stoves, and other appliances are serviced by qualified engineers at least once a year. Get in touch to find out more about our service maintenance plans.
Ventilate Properly
Keep vents and chimneys clear of blockages.
Choose Safe Heating Solutions
Opt for eco-friendly heating systems, like air source heat pumps, which don’t produce CO.
Regulatory Requirements for Employers and Landlords Regarding Carbon Monoxide
Understanding and adhering to carbon monoxide (CO) safety regulations is crucial for both employers and landlords to ensure the well-being of occupants and compliance with the law.
Responsibilities of Employers:
Employers have a legal duty to provide a safe working environment, which includes mitigating the risks associated with CO exposure. Key responsibilities include:
Risk Assessment
Conduct regular assessments to identify potential sources of CO and implement control measures to prevent exposure.
Installation of CO Detectors
Where appropriate, install CO detectors to monitor levels and provide early warnings of dangerous concentrations.
Maintenance of Equipment
Make sure all fuel-burning appliances are properly maintained and serviced regularly to prevent CO production.
Employee Training
Educate employees on the dangers of CO, how to recognise symptoms of poisoning, and the procedures to follow in case of a suspected leak.
Failure to implement these measures can lead to legal consequences and jeopardise employee safety.
Responsibilities of Landlords:
Landlords must comply with specific regulations to protect tenants from CO poisoning. As of October 1, 2022, the Smoke and Carbon Monoxide Alarm (Amendment) Regulations 2022 mandate that landlords:
Install Smoke Alarms
Equip at least one smoke alarm on every storey of their properties where there is a room used as living accommodation.
Install CO Alarms
Provide a carbon monoxide alarm in any room used as living accommodation that contains a fixed combustion appliance, such as a gas boiler or wood stove (excluding gas cookers).
Maintain Alarms
Make sure smoke and CO alarms are repaired or replaced once informed and found to be faulty.
Non-compliance can result in enforcement actions and fines of up to £5,000.
