Main causes of carbon monoxide poisoning
If you suspect a problem

K25 install the only CORGI approved carbon monoxide detector on the market.

The SF350 is the UK's best selling carbon monoxide product. Using the latest electrochemical sensor technology, the SF350 gives an audible and visual warning long before the level of carbon monoxide reaches a dangerous level.

The SF350 has the added benefit of being compact enough to be portable. For added peace of mind they should be an essential part of your holiday kit.

Death and injury, such as permanent brain damage, by carbon monoxide (chemical symbol: CO) poisoning is preventable with the right safety checks in place.

   
Carbon monoxide is absorbed into the body through the lungs and attaches itself to haemoglobin in the blood. Carbon monoxide starves the body tissue of vital oxygen, suffocating you from the inside out. When carbon monoxide is inhaled into the body it combines with the blood, preventing it from absorbing oxygen.
   
Approximately 30 people die every year from carbon monoxide poisoning. Every one of us is a potential victim.
   
It is illegal for anyone other than a CORGI registered engineer to touch gas – you could be fined £5,000, imprisoned or worse still and kill someone – Don’t be tempted
   
Carbon monoxide poisoning can have long lasting effects on health, quality of life and work which cannot be reversed if high or prolonged exposure to CO has occurred.
   
Carbon monoxide is caused by incomplete burning of fossil fuels – e.g. gas, oil and coal from engines, oil burners, gas fires, water heaters, solid fuel burners and vehicles
   
Carbon monoxide is odourless, colourless and tasteless,  leaving anyone exposed at danger
   
Carbon monoxide can kill without warning in just a few hours
   
Boats and caravans are also potentially at risk
   

Preventative measures

Carbon monoxide poisoning is easily preventable, so it's important to be aware of what may cause it and how to minimise the risk of exposure by putting these safety tips into practice:

Make sure gas appliances and heating systems are inspected every year by a CORGI registered engineer
   
Install* audible carbon monoxide detectors one per gas appliance
 
* Please note: Installing a carbon monoxide detector isn’t a substitute for having your appliances checked and maintained annually by a CORGI registered engineer
   
Never run cars, motorbikes, lawnmowers or petrol driven generators in a confined space
   
Never block or obscure air vents
   
Have chimneys swept regularly
   
Have flues checked regularly
   
Never be tempted to “fix” the problem yourself – ALWAYS use a CORGI registered engineer
   


What are the symptoms of carbon monoxide poisoning?


The symptoms of poisoning can vary depending on the level of absorption by the human body.  While most people are aware that high levels of carbon monoxide are harmful, it is  less well known that the length of exposure is also important. A relatively low level of carbon monoxide for a long period of can cause the same symptoms as a high level of carbon monoxide for a short period.


Carbon monoxide symptoms are often mistaken for flu


A major concern is that the symptoms of carbon monoxide poisoning can often and easily be mistaken for flu.  Patients presenting the usual symptoms are very rarely tested for carbon monoxide by their GPs.  After conducting a survey, Poisons Expert, Professor John Henry, found that the majority of GPs misdiagnosed carbon monoxide poisoning as flu.  Thus resulting in thousands of people suffering from undiagnosed carbon monoxide poisoning especially in the  winter.

   
Breathlessness
Dizziness
Erratic behaviour
Fatigue
Headache/Nausea
Stomach pains
Visual problems
Vomiting
   


How do I know if I am risk?

Although carbon monoxide is a colourless, odourless gas there are some significant danger signs to look out for that indicate you could be at risk:-

Staining, sootingYellow or orange flame – it should be blue
Rusting or water streaking on appliance
Loose or disconnected vent
Increased condensation on windows
Pilot lights that frequently blow out
Act on your instincts - If you think there is a risk get it checked out by a CORGI registered Engineer
   

What are the main causes of carbon monoxide poisoning?


There are several different causes of carbon monoxide poisoning:-

Ventilation
Poor maintenance of appliances
Chimneys - can become blocked for various reasons. It could be as a result of birds nesting on the chimney, or possible degradation of the flue.
Blocked or leaky flues can lead to carbon monoxide leaking into your home
   
Backdrafting

With an increase in the number of devices which extract the air from the home, e.g. bathroom extractor fans and kitchen vents, in conjunction with the more energy efficient homes, a negative pressure situation may occur within a home.  This results in a reverse in the airflow spilling carbon monoxide into the living area.

The severity of carbon monoxide emissions in the home will often be exacerbated in new energy efficient homes, particularly where double glazing has been installed.  This removes the draughts so often associated with older properties where a natural ventilation system existed.

   


If you suspect a problem associated with carbon monoxide
:-

   
Switch of the appliance and do not use until it has been properly checked by a CORGI registered engineer
Shut off the gas supply – and call Transco if you think it is still leaking - Freephone Number 0800 111 999
Ventilation is vital – open all windows and doors – do not sleep in the room
Seek medical advice immediately
Contact a CORGI registered engineer and get the system thoroughly checked
