Fire and rescue services are warning the public to be extra vigilant following the announcement by the Fire Brigades Union of three more strike days, including parts of Christmas Eve and New Year's Eve.
The union, in dispute with the Government over pension reforms, has scheduled strikes from 7pm-midnight on Christmas Eve, 6.30pm-00.30am on January 1 and 6.30am-8.30am on January 3.
Chief Fire Officer for Devon & Somerset Fire & Rescue Service, Lee Howell, said: "Our plans have worked well during the previous periods of action, but we are asking the public to help us again by taking extra care during the festive period. We will continue to respond to 999 calls."
The service warns that Christmas lights should always be switched off before householders go to bed and candles should never be left burning unattended.
