Beware of mirror danger in sun.
It comes after a man and his wife, were treated for smoke inhalation after a fire in their property on The Highway, Hawarden, during Friday afternoon.
The cause of the fire is thought to be sunlight on a mirror.
Justin Evans from North Wales Fire and Rescue Service, said the sun''s rays can be magnified by a lens, or a magnifying mirror, and become focused on a nearby object.
It can cause: "scorching, or charring potentially leading to smouldering or flaming ignition of the object," he said.
"In the evening, morning and during the winter, when the sun is lower on the horizon, the shallower angle at which the sun''s rays hit the earth means that it is particularly important to be aware of objects, such as magnifying vanity mirrors and glass ornaments, which may be left exposed to direct sunlight."
