A total of 36 recruits are officially fully fledged members of Dublin Fire Brigade following 13 weeks of rigorous training.
The recruits demonstrated some of the skills they have developed over the course of their training during the passing-out ceremony in Marino yesterday.
These included exercises in dealing with hazardous materials and road traffic collisions.
In addition, recruits have received specialist instruction in the use of breathing apparatus.
Dublin Lord Mayor Paul McAuliffe presented a Silver Axe to the best recruit - firefighter Derek Baitson, who attended the event with his family.
Mr McAuliffe said the city should be proud of the 2019 class of recruits.
"The calibre of the recruits passing out is a testament to the hard work and dedication of the instructors and of the recruits themselves," he said.
"Dublin Fire Brigade provides a vital service to the city and county of Dublin and I have no doubt that all firefighters joining the ranks of Dublin Fire Brigade will continue to uphold that proud service."
He said that having undergone meticulous instruction, the new recruits would graduate with the knowledge and specialist skills that would equip them to work alongside their professional firefighter and paramedic colleagues in Dublin Fire Brigade.
