FIREfighters' leaders in the North-East said union members had backed the 24-hour strike "100 per cent".
It is hoped that Acas negotiations between union and employers being held today will be enough to avert further planned strike action on January 28 and February 1.
Cleveland Fire Brigade Union Chairman Kevin Gelders said the planned 48-hour strikes would "remain on the table unless the employers' pre-conditions to negotiations were removed".
In the latest 24-hour action there were 57 fire-related incidents in the North-East and 33 false alarms.
