Firefighters will go on strike for the second time this month on Saturday.
The Fire Brigades Union has called the action for between 10am and 5pm.
As with previous periods of industrial action, Northumberland Fire and Rescue Service has plans in place to provide a service during the strike.
Alex Bennett, chief fire officer, said: “We have a duty to ensure we have robust plans in place to provide a fire and rescue response during industrial action, and we are once again putting these plans in place.
“Homes and businesses should take extra precautions as it will not be business as usual.
“We’re again asking people 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.”
