they give me 4 4x4x4 boxes which i now think are called gaylords, they give me o2 tanks mainly probably right at half, some forklift propane tanks with the valves out, and some other stuff i dont know what they are kinda look like a bomb that would fit on a ww2 plane, and believe it or not more fire extinguishers, and some kind of aluminum tanks with chambers in them with an opening at each end. with the conversation i had with the yard manager i would be getting all tanks from now on
