                                            CARBON MONOXIDE (CO) gas is produced when ordinary fuels burn; for example, oil, natural gas, coal and turf. It is COLOURLESS and ODOURLESS. When inhaled, it prevents the blood cells from carrying enough oxygen around the body. All organs can be harmed by the lack of oxygen. High levels of CO can quickly kill, but even lower levels can have long lasting effects.
WHAT CAUSES EXPOSURE TO CO?
 Incorrectly installed, poorly maintained or poorly ventilated household appliances; for example, gas cookers, heaters and boilers, are the most common causes of accidental exposure to CO.
 Other possible causes may include blocked flues and chimneys or burning fuel in an enclosed or unventilated area.
SYMPTOMS OF CO POISONING
 A tension-type headache is the most common symptom reported.
 Other symptoms include; dizziness, feeling or being sick, tiredness and shortness of breath.
 Symptoms of low level CO poisoning can be similar to food poisoning and flu.
 CO poisoning does not cause a high temperature.
Other clues that may indicate CO poisoning include:
 Symptoms occur when an appliance is on.
 Other people in the house suffering similar symptoms.
 Symptoms improve when you are outside.
WHAT TO DO IF YOUR CO ALARM SOUNDS OR YOU SUSPECT CO EXPOSURE
 Turn off any fuel burning appliances.
 Open doors and windows to ventilate the area.
 Get everyone to fresh air in a calm manner.
 If you or anybody feels unwell call an ambulance.
 If you do not develop symptoms call a qualified service agent to check your appliances before reusing them.
 If you are concerned call the Carbon Monoxide Awareness Line on 1850 797979.
PREVENTING CO POISONING
 Boilers, gas cookers and heating systems should be installed and regularly serviced by a registered engineer.
 Make sure all flues and chimneys are kept clear and swept regularly.
 Never block room vents.
 Do not use appliances you suspect may be faulty.
 Install a CO alarm that complies with European Standard EN5029. Follow the manufacturer's instructions or have a qualified installer fit it for you.
Call 01- 8092166 if you suspect CO poisoning.
