HWFRS is encouraging people to heed the advice as it pledges its support to the 14th annual Gas Safety Week (September 9-15).

Emma Roberts, HWFRS head of prevention, said: "I would urge people to ensure they have their appliances checked by a professionally-qualified Gas Safe engineer.

"This will provide vital protection against the dangers of unsafe gas appliances, not only from fires, leaks and explosions but also carbon monoxide poisoning.

"It's also important not to risk your health or mental welfare by tackling 'fuel poverty' by reducing heating, hot water or cooking or skipping necessary gas appliance repairs or servicing to save on cash.

"I'd also encourage everyone to keep an eye on elderly or vulnerable relatives and neighbours who may be particularly struggling at the moment."

Be aware of the signs that an unsafe gas appliance may cause such as a lazy yellow flame instead of a crisp blue flame, soot or staining on or around the appliance or excess condensation in the room.

Know the symptoms of carbon monoxide (CO) poisoning. CO gas is known as the 'silent killer' as it has no smell, taste or colour. The symptoms of CO poisoning include headaches, dizziness, nausea, breathlessness, collapse and loss of consciousness which can easily be mistaken for something else.

Always ask to see an engineer's Gas Safe ID card and check it to ensure the engineer is qualified to work on the appliance in question.
