Firefighters have urged people to take extra care ahead of strike action this weekend.
Members of the Fire Brigades Union (FBU) will walk out for four hours from 6pm on Friday, December 13 and Saturday, December 14 as a dispute over pensions rumbles on.
West Yorkshire Fire and Rescue Service has urged residents across the area to unplug their Christmas lights when leaving their homes this weekend.
Dave Walton, assistant chief officer, said: “The previous four strike periods have passed without major incident and our contingency measures have stood us in good stead.
“This time around we are into the run-up to Christmas and people may well be looking forward to parties this weekend.
“Whilst we do not want to spoil anyone’s fun, we hope the public can help us by helping themselves.
“We always remind drivers that roads can be hazardous in December, so if you are going out ensure your vehicle is prepared, drive carefully and never drink and drive.
“Before you leave your home turn off Christmas lights and remember to snuff out candles. When you return from a night out do not set about making a meal – alcohol and cooking do not mix.
“Ultimately we want people across West Yorkshire to enjoy this festive period safely.”
