Some of the solvents are harsh smelling, but doesn’t give me side effects.
I work in aircraft and am around MEK, MPK, TOLUENE, NAPTHA’S, and various paints and coatings. Some of these can be quite offensive in large amounts.
There was a guy up in a fuselage that had to be pulled out feet first when he started working with us. Come to find out from medical that was allergic to MEK, so he quit to go work somewhere else.
