Notts Fire and Rescue Service were called out four times in the first hour of the industrial action.
And by 10pm, the service had received 27 calls, with crews attending 13 minor incidents.

Chief fire officer, John Buckley, said: “It is regrettable that the on-going dispute between the FBU and the Government has not yet been resolved, which has been our wish for some time now. But, with the public’s help, let’s hope we can keep the number of incidents this weekend to a minimum and ensure a safe weekend for all.”
The strike will continue until 6pm on Tuesday 4th November.
