Carbon Monoxide
Carbon monoxide
Badly fitted and poorly serviced gas appliances can cause carbon monoxide poisoning. Carbon monoxide is a poisonous gas. It has no taste, colour or smell and it can make you feel seriously ill. If you are suffering from headaches, dizziness, nausea, breathlessness, collapse or loss of consciousness, it might be a sign of carbon monoxide poisoning.
Gas safety advice
- Never use a gas appliance if you think it is not working properly.
- Never cover an appliance or block any ventilation grills or air bricks
- Never block or cover outside flues
