They think “metal tech” is metal. They don't consider the whole scope of our work.
You can pull back the testimony from Marie-Ève Doucet. I have worked with her on the flight lines. I have changed engines with her. I have felt the jet fuel fall down and go into my lymph nodes and the hydraulic seep through my brain and seep through my skin. Our skin is the biggest organ. How can I even use gloves when the ketone melts the gloves? It's all of those things.
Also, those microparticles are from the aircraft being there, from the JP-8. If I'm doing a repair on a jet, I don't necessarily have the whole thing, so I have to sand. Once you sand down polyurethane paint, it releases very toxic microparticles of isocyanates. Isocyanates seep into the skin and the pores—everywhere.
I'm even worried about the janitors. The janitors should be covered. We have canteens in those buildings. Our food is made in those buildings, buildings that were created in the 1950s, not to save the technicians but just for the war. They were meant to be temporary.
