Higher exposures can cause a build up of fluid in the lungs and pulmonary edema. It can affect liver and kidneys, damage nervous system, causing numbness, “puns and needles”, and/or weakness in the hands and feet, and may cause a skin allergy. High exposure can cause dizziness, irritability, difficulty with concentration and reduced memory. Workplace exposure limits are 100 ppm over 8 hrs shifts or 50 ppm if longer term exposures.
