  1. Ironically it was the manufacturing of shells and explosives that led to the use of Nitro Glycerine or Glyceryl Tri Nitrate as a treatment for Angina, as due to the effects of the nitro in explosives very few workers ever suffered from the illness. They did suffer from "nitro headache" which was due to the effect that it opened up blood vessels. Some people also had their skin take on a yellow tinge. My great grand mother worked in munitions in WW1 in UK, later became a nurse, and in WW2 nursed and also worked on sewing the fabric on aircraft in particular the Hurricane. After ww2 she was a nurse and used GTN with patients on a regular basis.
