The Fire Brigades Union plans to take a second period of strike action on Saturday, October 19, between 6.30pm and 11.30pm.
Northumberland Fire and Rescue plans to provide a service but stresses it will not be business as usual.
Residents are encouraged to take steps to protect themselves and their homes from the risks of fire and other emergencies and the service has already written to businesses in the county to help them to minimise the risk from fire.
Councillor Dave Ledger, deputy leader of Northumberland County Council said: “We are obviously disappointed that issues between the Fire Brigades Union (FBU) and the Government over reform of the fire-fighters pension scheme have still not been resolved.
“The council in its role as Northumberland Fire Authority has a duty to ensure it has robust plans in place to provide a fire and rescue response during industrial action, and we will be putting these plans into action again.
“We must stress that it will not be business as usual however, and homes and businesses should take extra precautions.”
Alex Bennett, chief fire officer for Northumberland Fire and Rescue Service, added: “Our contingency plans were effective during the first period of strike action, and we will use similar processes and procedures to provide an emergency service during this period too.
“We continue to urge residents to take steps to protect themselves and their loved ones from the risks of fire, including ensuring they have working smoke alarms fitted in their homes.”
