The video shows a high-angle view of a warehouse aisle with three workers and three small electric pallet stackers. The aisle is surrounded by tall metal shelves stocked with boxes. Two workers are operating pallet stackers to move boxes on pallets. The third worker appears to be inspecting or adjusting a pallet stacker. One worker is wearing a white long sleeve shirt with a hat. Another is wearing a dark short-sleeve shirt, with his back turned to the camera. The third worker is wearing a long-sleeved shirt and vest and shorts. Numbers 14 and 15 are clearly visible on the metal supports for shelving. A fire extinguisher is also visible. The lighting is bright, and the floor is concrete.
