I still have an HII access card for when I worked on the USS Chosin and USS O'Kane right underneath the Coronado bridge. I was still in the custody of the San Diego sheriff's department at the time. Many of the few hundred of us that worked there were either currently in a halfway house or ex-cons. None of us received any safety training on asbestos, yet we handled a-cloth every single day. We only had rudimentary safety equipment. Some guys would cut asbestos cloth with a hand grinder, sending fluff everywhere. Equipment marked "TOP SECRET" was covered with a simple piece of butcher paper...assuming it hadn't torn or fallen off. It was pretty much a shit show.
