Carbon monoxide poisoning
Carbon monoxide is a colourless, odourless gas. If you breathe it in (inhale it) it can cause illness and in severe cases death.
Where carbon monoxide is found
Carbon monoxide comes from a range of sources. This can include emissions from:
- wood, paper or fuel that has not been burned properly (carbon-based materials)
- cars, trucks, forklifts (internal combustion engines)
- kilns, boilers and BBQs
- welding and plastics moulding
- space heaters, oil or gas heaters
- hookah, narghile and shisha (waterpipe smoking).
Carbon monoxide from these sources can build up in enclosed or semi-enclosed spaces, for example if windows are shut. Small, enclosed spaces such as caravans and tents pose a greater risk as carbon monoxide levels can build up quickly, particularly during cold temperatures when windows and tent flaps are closed.
Symptoms of carbon monoxide poisoning
Common symptoms of carbon monoxide poisoning include:
- headache
- dizziness
- weakness
- confusion
- feeling sick (nausea).
High levels of carbon monoxide poisoning can cause:
- chest pains
- hallucinations
- convulsions
- loss of consciousness
- death.
Who is at greatest risk of carbon monoxide poisoning
Carbon monoxide poisoning is dangerous for everyone. But certain groups are more at risk if they are exposed to carbon monoxide, including:
- infants
- unborn pēpi
- people with chronic heart disease, anaemia, or respiratory problems.
How to prevent carbon monoxide poisoning
- Move carbon monoxide generating processes outside to allow good ventilation while operating.
- Have your heating systems, including hot water, and any other gas, oil, or coal burning appliances serviced by a qualified technician every year.
- Do not use unflued gas heaters, cookers or portable flameless chemical heaters (catalytic) indoors. These appliances burn gas and can cause carbon monoxide to build up inside your home.
- Never run a car or truck in the garage with the garage door shut.
