DMS
Acute (short-term) exposure of humans to the vapors of dimethyl sulfate may cause severe inflammation and necrosis of the eyes, mouth, and respiratory tract. Acute oral or inhalation exposure to dimethyl sulfate primarily damages the lungs but also injures the liver, kidneys, heart, and central nervous system (CNS), while dermal contact with dimethyl sulfate may produce severe blistering in humans. Human data on the carcinogenic effects of dimethyl sulfate are inadequate. Tumors have been observed in the nasal passages, lungs, and thorax of animals exposed to dimethyl sulfate by inhalation.
I didn’t expect the DMS when I went to investigate the bunker and really didn’t know what it was until I was able to research it a couple hours later.
As I read the MSDS and other literature I began to cough, sniff, have some itching and felt a little tightness in my chest...and I had to reassure myself that I was only experiencing psychosomatic symptoms as I read the signs and symptoms of exposure.
It’s funny now of course.
