Heh, my duty had me 8+ hours a day, five days a week, in buildings that used asbestos for insulation. We also used Trichloroethylene as a staple for cleaning electronics in timers and transmitters. I feel pretty lucky at this point considering my age.
I was in Naval Air but attached to an aircraft carrier '70 to '72 in the Tonkin Gulf and the South China Sea in the Vietnam War. Like most ships of that time,
asbestos was everywhere, as steam spun the turbines to propel the ship.
Being a carrier, it was afloating fuel farm with
avgas for propeller-driven airplanes,
JP-4 for the jets and
fuel oil (Bunker C) for the ship....the fumes were in the air constantly. My berthing compartment where I slept was atop tanks containing thousands of gallons of all 3.
Vietnam-era aircraft carriers primarily used
Aqueous Film-Forming Foam (AFFF) for firefighting, particularly for dangerous liquid fuel fires on the flight deck and in engineering spaces. I took my turns during flight ops dumping the bright red cans (that had a skull and crossbones insignia on it) of the liquid into a fog
fog foam generator for deck firefighters to use when an aircraft crashed and burned trying to land on the carrier. The original AFFF formulations contained per- and polyfluoroalkyl substances (PFAS), including PFOS and PFOA, which are now recognized as persistent environmental contaminants with potential health risks. These formulations are no longer used because of those health risks.
I got out in '72 then starting the very next year in '73 I spent the next 31 years in traffic signals and facility maintenance and the neon transformers for the older "WALK/DON'T WALK" signals for pedestrians and the fluorescent lighting ballasts in the facility lighting and most stepdown transformers were filled with
PCB's (Polychlorinated biphenyl) oil as a coolant. I've had the smelly, sticky oil smeared up to my elbows for hours as it would leak out when the equipment that contained it overheated.
All of the aforementioned things...
asbestos, hydrocarbon-based fuels, Aqueous Film-Forming Foam and PCB's....are known to either be carcenogenic and/or impose other serious health issues after prolonged exposure.
And then I smoked 22 years from '65 to '87 and my colorectal cancer was discovered in Dec. '24. I cannot imagine how I contracted cancer.

After 30 radiation treatments, 8 chemotherapy IV's and about 300 chemotherapy oral pills between Feb. and Aug. of this year ('25),
and by God's boundless mercy and grace, all the scans and blood tests look good.
I'm hangin' in there, like a hair in a biscuit.
