A white truck with a tank that reads "XE CHỞ XĂNG DẦU" (which translates to "Fuel Tank Truck") is spraying a dense white foam or mist. Flames are visible coming from containers on the ground next to the truck's rear wheel. Another vehicle is positioned in front of the fuel truck, also being sprayed with foam. In the background, there are grandstands, stage setups, and people, some of whom are wearing protective gear and holding hoses, suggesting a controlled demonstration or emergency response. The ground appears wet, indicating the use of water or foam. The environment suggests an outdoor public space, possibly a plaza or a venue with event infrastructure.
