Gas safety

• Ensure that all gas appliances are serviced at least once a year by a registered Gas Safe Registered Engineer: www.gassaferegister.co.uk

• Fit a Carbon Monoxide Detector.
• Be aware of the position of your gas meter and mains valve.

Carbon Monoxide
If any of your gas appliances are faulty, they may produce Carbon Monoxide. This is a dangerous by-product of natural gas and is colourless and odourless. If your gas appliances are burning orange or yellow, there could be Carbon Monoxide present. If in doubt you should have the appliances checked by a Gas Safe Registered Engineer: www.gassaferegister.co.uk
