Crawley firefighters will join a national strike this week in the on-going dispute with central Government over pensions.
Members of the Fire brigades Union will strike on Friday (December 13) and Saturday (December 14), from 6pm to 10pm.
During the strike Crawley firefighters will be responding to 999 calls, but have fewer resources available.
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.”
