The Fire Brigades Union (FBU) is planning a fifth period of strike action on Friday and Saturday, December 14/15, between 6pm and 10 pm on both days.
West Yorkshire Fire and Rescue Service (WYFRS) said it was confident with its contingency plans, but appealed for people to take extra.
Assistant Chief Officer Dave Walton 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.
“Whilst we do not want to spoil anyone’s fun, we hope the public can help us by helping themselves.”
Motorists are uged to be wary of potentially hazardous roads at this time of year and homeowners should switch off Christmas lights and snuff out candles before leaving their homes.
The decision for strike action relates to an on-going trade dispute between the FBU and the Government over its public sector pension reform programme.
During full strike action WYFRS anticipates having around half of its normal fleet of 54 engines available.
These will be strategically placed across the county and manned by non-striking staff and Community Response Operatives (CRO) who have undergone three weeks training.
