The event at the station in Icknield Road was organised by Oxfordshire Fire and Rescue Service and took in hopefuls from as far as Didcot.
The volunteers began by climbing a 13.5m ladder on the drill tower before doing a ?leg lock?, which involves wrapping a foot around a rung and leaning backwards. The second challenge was to pull a 90kg dummy around a course and carry heavy items from one side of the yard to the other.
Finally, they were asked to throw out a length of hose before rolling it back up as fast as they could.
Marcus Reay, station manager for Goring, Wallingford, Watlington and Henley, said: ?We asked members of the public to come down and have a go at the tests they will be doing at selection. It?s making sure they are not frightened of heights and testing their strength and cardio. The real tests will be a little harder but we wanted to give them a bit of encouragement. We are pleased with the candidates who were all very enthusiastic and willing to learn.?
Ryan Bonner, 22, of Wallingford Road, Goring, is an on-call firefighter at the station and a home and community safety advisor for the service.
He said: ?I?ve been a firefighter for two years and love the variety as well as the practical and team aspects. I found out about it by going down to my local station. I?m able to do my day job and do firefighting in my spare time.?
On-call firefighters must live or work within five minutes of their local station. They are paid for their time on both incidents and training.
