A fire broke out in a bathroom of a Burnley house on Wednesday morning.
Two fire engines were called to the house in Pembroke Street at 9-30am after reports of a fire in an upstairs bathroom.
Firefighters used four breathing apparatus wearers, a hose-reel jet, two positive pressure ventilation fans, and two thermal image cameras.
Acting crew manager Kevin Birchall said: “The damage to the bathroom was the first floor was severe.
“Investigations are currently ongoing but the cause is thought to be accidental.
“There was a working smoke alarm in the property and this will have given the resident an early warning and extra time to evacuate.
“We would always recommend that smoke alarms are tested regularly. A smoke alarm is the easiest way to alert you to the danger of fire, giving you and your family precious time to escape.”
