Also in a lot of ways the military just seems to have safety standards a few decades behind everyone else. Various fuels, solvents and lubricants they use for aircraft etc. also contain carcinogenic compounds, and they just seem to have a history of never disposing of them properly (an example is the burn pits in Afghanistan where they would just dig big holes and burn toxic solvents along with plastic waste etc. in the air, causing huge health problems and many deaths for a lot of veterans).
