Llandudno fire: Electrics warning after short circuit starts blaze
North Wales fire chiefs have warned about the dangers of electrical fires after a blaze at Llandudno.
Fire investigators believe the fire in Trinity Avenue was caused by an electrical short circuit in an under-stairs cupboard.
A man and a woman remain in intensive care after suffering from smoke inhalation and severe burns in the incident on Wednesday morning.
Another man is also in hospital with minor injuries.
Colin Hanks, assistant chief fire officer of North Wales Fire and Rescue Service, said the danger of electrical fires was that they could strike "anytime, anywhere".
"It's important to be as prepared as possible in the event of fire, by ensuring that working smoke alarms are fitted in your home and that you have clear escape routes."
Mr Hanks appealed for householders to ensure areas housing electrical items, such as a fuse box, are kept clear of rubbish, papers or other combustible materials which could help a fire to spread.
"There are simple steps which you can take, including not overloading plug sockets, regularly checking for worn or frayed wires, unplugging appliances when not in use, and keeping appliances clean and in good working order," he added.
On Wednesday the Welsh Ambulance Service said paramedics treated the woman at the scene for severe smoke inhalation and first degree burns to her hands, arms and feet.
They also helped the man who had first degree burns to his arms and superficial burns to his back.
The third casualty, a second man, was suffering from smoke inhalation and a minor injury to his hand.
All three were taken to Ysbyty Glan Clwyd at Bodelwyddan.
