The fire service is urging people in West Sussex to take extra care if planned strike action by members of the Fire Brigades Union (FBU) goes ahead on Saturday (October 19).
West Sussex Fire and Rescue Service (WSFRS) said it had robust contingency plans in place to minimise the impact of strike action and to maintain emergency services to the public.
The FBU is involved in a dispute with the government over changes to firefighter pensions, and has called for a second round of national strike action between 6.30pm and 11.30pm on Saturday.
This comes after the initial FBU strike on Wednesday, September 25.
A spokesman for the fire service said: “WSFRS expects to have fewer resources available and we realise it will be challenging to meet normal emergency response times.
“However, our experience from the first strike action in September has shown our contingency plans work, and this was helped by the public taking note of safety advice and reducing the number of 999 calls made.
“Simple steps, like ensuring your home has a working smoke alarm, not leaving cooking or candles unattended, and extinguishing cigarettes properly can make the difference between needing to dial 999 or not.
“We therefore again urge residents, drivers, and businesses to take extra care, but to still dial 999 if we are needed for a genuine emergency.”
