Povijest vatrogastva u Gaju seže u daleku 1907. godinu kada je na inicijativu nekoliko mještana Gaja osnovano vatrogasno odjeljenje koje je funkcioniralo kao ispostava DVD-a Vrbovec. DVD Gaj je utemeljen 1935. godine. Tada je izabrano i prvo vodstvo: predsjednik Đuro Habijanec, zapovjednik Mato Hrgović, tajnik Vid Drvenkar i blagajnik Ignac Pankretić. Nakon Drugog svjetskog rata 1946. društvo se proširilo i biva sve aktivnije. Godine 1948. održano je kotarsko vatrogasno natjecanje, a vatrogasci Gaja su osvojili 1. mjesto. Pripreme za gradnju vatrogasnog doma počele su 1956., koji je završen 1958. godine. Izgradnjom vatrogasnog doma povećana je aktivnost te je nabavljena prva motorna šprica „Savica“. Godine 1971. izvršeni su radovi na vanjskoj fasadi vatrogasnog doma, a 1975. godine nabavljena je šprica „Rosenbauer“. Članovi DVD-a Gaj su pod zapovjedništvom Franje Habijanca sudjelovali u saniranju posljedica katastrofalnog avionskog sudara dvaju zrakoplova, koji se dogodio 10. rujna 1976. godine, u kojem je jedan avion pao nad Gajem u polje Krč. Od RSUP-a vatrogasci Gaja su dobili zahvalnicu za brzi izlazak na mjesto avionske nesreće i za primjereno zalaganje i uloženi trud u gašenju požara i pružanju pomoći. DVD Gaj osniva 1979. godine žensko odjeljenje, a zapovjednica je Marica Brlečić, voditeljica Jela Tretinjak i blagajnica Zorica Tretinjak. Godine 1997. godine u DVD-u se osniva i dječje odjeljenje. Uz potporu tadašnjeg ministra poljoprivrede Božidara Pankretića Lura-grupa je DVD-u Gaj donirala auto cisternu kapaciteta 10 tisuća litara vode čime započinje novo razdoblje u djelovanju društva. Vatromenika je prenamijenila auto cisternu u vatrogasnu cisternu i od 2005. godine vozilo je u funkciji.

The history of firefighting in Gaj dates back to 1907, when, on the initiative of several local residents, a firefighting unit was established, operating as a branch of DVD Vrbovec. DVD Gaj itself was founded in 1935. Its first leadership was elected at that time: Đuro Habijanec as president, Mato Hrgović as commander, Vid Drvenkar as secretary, and Ignac Pankretić as treasurer. After the Second World War, in 1946, the brigade expanded and became increasingly active. In 1948, a district firefighting competition was held, where the firefighters of Gaj won first place. Preparations for the construction of a fire station began in 1956, and the building was completed in 1958. The construction of the fire station increased the brigade’s activities, and its first motor pump, a “Savica”, was acquired. In 1971, work was carried out on the exterior façade of the fire station, while in 1975 a “Rosenbauer” fire pump was purchased. Under the command of Franjo Habijanec, members of DVD Gaj participated in dealing with the consequences of a catastrophic mid-air collision between two aircraft on September 10, 1976. One of the aircraft crashed in a field known as Krč near Gaj. The firefighters of Gaj received a letter of appreciation from the RSUP for their prompt response to the scene of the aircraft accident, as well as for their dedication, efforts, and contribution to extinguishing the fire and providing assistance. In 1979, DVD Gaj established a women’s section. Its commander was Marica Brlečić, Jela Tretinjak served as its leader, and Zorica Tretinjak as treasurer. In 1997, a children’s section was also established within the brigade. With the support of the then Minister of Agriculture, Božidar Pankretić, the Lura Group donated a 10,000-litre water tanker to DVD Gaj, marking the beginning of a new era in the brigade’s activities. Vatromenika converted the vehicle into a firefighting water tanker, and since 2005, the vehicle has been in service.
