i guess those 3 men were thinking about their families also at that time before making that action.. cause they were told that their families will be taken care by the government and back in soviet times its like an honor and at the same time it ll be a best thing to happen for those families.. im not sure they were firefighters i remember it more like night shift workers did that..
i have small video about the disaster that i post here earlier if you like to see..
