Frank M., KY

I joined the military 31 Mar,1960 and was sent to HVAC Tech school and that's when I was exposed to phosgene gas and welding/brazing fumes. Because I was a A/C refrigeration Tech I was constantly exposed the fluorocarbon refrigerant's. I was exposed to 100% F-22 refrigerant for over 5-6 seconds. Now I have COPD and am on 2% oxygen plus I use AIbuterol and AdVAair 250mcg/50mcg plus I worked in factory environment's.
