The 16 of us were in like an enclosed room, as big as this, there were 8 rows on each side and there were two tables to the workshops, two workshops to two boys at that time, and 16 of us in an enclosed place. The only thing that we had is open windows on top for the smell of the gas to go, the smell of the aluminium as well, we used to wear goggles and on some welding we used to have masks as well, on the faces, but the job, for me the job was easy because I was used to welding and I helped as many boys as I could with the welding, and they appreciated it.
