Volunteers dealt with three incidents while South Yorkshire firefighters were out on strike over the weekend.
They were called out to a car found burning on High Street, Rawmarsh, Rotherham; a grill pan fire on Sheffield Road, Barnsley and a fire in the open off Scott Street, Attercliffe, Sheffield.
Firefighters began an eight day period of industrial action on Saturday, which will see them walking out between noon and 2pm and then 11pm and midnight daily.
The Fire Brigades Union is in dispute with the Government over changes to firefighter pensions and job security.
The union fears that aging firefighters deemed unfit for frontline duties will lose their jobs because of funding cuts resulting in a lack of back-office and community roles for them to move into.
There are 40 contingency firefighters who have been recruited and trained to provide emergency cover during periods of strike action.
Another 20 are in the process of completing their training.
High ranking officers, including Chief Fire Officer James Courtney, are also available to tackle blazes during the strike.
