In the video, a man is seen walking on a dock while holding a bucket of supplies. He then proceeds to place the bucket on the ground and walks towards a yellow container labeled "spill kit". The man then opens the container and takes out a red fire extinguisher. He then closes the container and walks away from it. The video seems to be a demonstration of how to use a spill kit, with the man showing the process of accessing the fire extinguisher from the kit.
