Firefighters across North Yorkshire are planning to strike between 12 noon and 4pm on Wednesday, September 25.
The action is a result of the Fire Brigades Union (FBU) ballott over government reform of firefighter pension schemes.
If the action goes ahead as planned, emergency calls will still be answered.
Many stations across North Yorkshire, particulary in rural areas, will be unaffected.
Non-FBU members will be working as normal, and fire engines will be placed in locations near to where crews are planning to strike.
Chief Fire Officer Nigel Hutchinson said; “I want to reassure the public that emergency (999) calls will still be answered during this time and contingency plans have been put in place to ensure we can still respond to emergency incidents.
“However, it would greatly help us if members of the public took extra steps during this time to reduce the risk of fires breaking out in their home.”
The service urged people to get out, stay out and call 999 if a fire breaks out.
