Badly maintained gas appliances have killed tenants by carbon monoxide (CO) poisoning. Carbon monoxide is created when the combustion of fuel is incomplete. You will not be able to smell or taste this gas.
Danger signs on the appliances might include:
-
Soot or sooty smell
-
A yellow or orange flame instead of blue
-
Scorch marks on any part of the appliance
-
Brown or black discoloration of burners
-
Cracked, damaged or blocked flues through which gas could escape
-
Pilot lights that frequently go out
-
Blocked ventilation
-
Excessive condensation
Symptoms of carbon monoxide poisoning include:
-
Drowsiness
-
Headaches
-
Dizzy feeling on standing up
-
Feeling sick
-
Chest pains
-
Tiredness, palpitations, diarrhoea and stomach pains
-
Unconsciousness
Minimise risks:
-
Make sure all appliances have been professionally installed and serviced within the last year
-
Do not seal up your room to make it draught free
-
Use appliances appropriately – gas cookers are not for heating kitchens
-
Open flue-type heaters in bathrooms and bedrooms should be used with particular care: keep the room ventilated and turn the heater off once you are in the bath or in bed
-
Do not restrict ventilation to any appliance and make sure all flues and chimneys are clear
Don’t compromise on safety. If your landlord does not respond quickly to an apparent problem with a gas appliance, stop using the appliance and contact the Environmental Health department of your local council or the Regional Health & Safety Executive, either of which can order a landlord to carry out work.
If you are worried that a gas appliance is unsafe:
-
Stop using it
-
Turn off the gas supply
-
Ventilate the room
-
Contact your landlord or Wales and West Utilities
Your landlord has a legal responsibility for making sure that gas appliances are professionally installed, well maintained and safe.
It is illegal for unregistered people to work on gas appliances. Ask to see a gas safety certificate.
