On the other hand, you could get acclimated to it.
When my agency ran a study at Radford, they showed us pictures of the old open vat system of making nitroglycerine. A 500 gallon tank that was filled with glycerine and nitrating acid (nitric + sulfuric acid blend) added gradually. The operator sat on a tall stool and adjusted a hose to keep the incoming acid at the interface between glycerine and nitroglycerine as it formed. They got acclimated to the NG fumes that dialated blood vessels and would come in to work on Monday with a headache from blood vessels in their heads constricting. So as soon as a little nitroglycerine was formed, they would wipe some on their hatbands and put the cap on to get their "fix."
