The Fire Brigades Union (FBU) has announced two further strikes in the on-going dispute with central government over pensions.
Members of the FBU will hold strike action on December 13 and 14, from 6pm until 10pm.
During the strike periods West Sussex Fire and Rescue Service will still be responding to 999 calls and providing an emergency response across the county, but will have fewer resources available.
An additional ballot of FBU members on taking action short of a strike closed on Wednesday (December 4) and resulted in a yes vote. No announcement has been made yet on how and when action will be taken under that ballot.
Chief fire officer for West Sussex Fire & Rescue Service, Sean Ruth, said: “Once again we have been working hard to ensure we are prepared for any possible strike action and have robust contingency plans in place to minimise any impact on the public. In an emergency people should still call 999 but we are urging everyone to take extra care and help to reduce the risk by following our fire and road safety advice.
“This action is taking place when many people may be enjoying festive celebrations - having a working smoke alarm is the single most important step people can take to ensure that and their loved ones are safe from fire during the festive season.”
