On 26 April 1986, following the initial explosion at the Chernobyl Nuclear Power Plant, Paramilitary Fire Brigade No. 6 was quickly called to the scene, the call out coming at 1:29 a.m. As Ignatenko was on duty that night, he was among the first 14 duty-watch firefighters from Pripyat to depart for the power station, located a mere 4 km away from the city.
