In Bolyarsko, Bulgaria, a close-up view captures a fueling operation at a tanker truck. The focus is on the connection point where a red, ribbed hose, marked with white and red bands, attaches to a silver metal coupling on the truck. This coupling features a yellow band and a red ring. A black handle with a red safety tag hangs from a wire attached to the coupling. In the background, a row of large white storage tanks is visible, one of which is labeled "T-03". The tanks are situated beneath a metal roofed structure, suggesting an industrial or storage facility. The ground appears to be concrete, with a drainage grate visible to the right. The overall environment is bright and appears to be outdoors, under a clear sky.
