two men working around a large truck with a tank mounted on the back. The truck is parked on a concrete surface next to a sidewalk and a street. The truck is marked with "EPS MSA" and a logo featuring a water droplet. A man in a vest and jeans walks towards the truck in the first seconds of the video. Another man, wearing a blue hard hat and a grey jumpsuit with reflective stripes, is seen near the back of the truck. The truck appears to be some type of sanitation or service vehicle. A blue and white-striped pole stands next to the truck. Buildings are visible in the background.
