Firefighters will strike for 24 hours in the ongoing dispute about pensions.
Members of the Fire Brigades Union will walk out from 9am on Tuesday.
Fire services in the area have called on residents and businesses to be alert and vigilant during strike action. Plans are in place to ensure fire cover is maintained and a response is made to 999 calls.
Cambridgeshire Fire and Rescue Service deputy chief fire officer Chris Strickland said: “We will be working hard during the coming days to ensure our resilience arrangements are in place to provide a reasonable level of emergency cover across the county, as we have with all previous periods of industrial action.
“We urge all residents and businesses to take extra care during this 24 hour strike period, whether it be in the home, at work or on the road.”
