As New Year’s Eve parties get underway firefighters will have walked-out.
The latest strike in a dispute over pensions takes effect from 6.30 pm to 12.30 am.
West Yorkshire Fire and Rescue Service (WYFRS) is urging people to bring in 2014 safely.
Assistant Chief Officer Dave Walton said: “New Year’s Eve is a time when we can experience an increased level of calls.
“Whilst we are confident that our contingency plans will once again prove effective, we are mindful that we will be experiencing reduced cover during a risky period.
“Please do your bit to help us by looking after friends and family, staying safe on the roads and reducing fire risks in your home.”
On average over the last five years, WYFRS has attended 20 call outs between the hours of 18.30 on New Year’s Eve and 12.30 on New Year’s Day.
A further strike is anticipated on Friday, January 3, between 6.30 am and 8.30 am.
