I worked in a plastic factory and had to clean out this thing that had hot recycled methylene chloride in it...no breathing apparatus either..didn't know how bad it was until years later after I left..I was inhaling the fumes I guess..that was 27yrs ago so I guess I am ok.Besides that driving a truck into Hunts Point,Nyc,the bronx and parts of Long Island..oh newark and East Orange too..got held up at gun point in the bronx in an elevator at a project..that should be the worst but I didn't get shot who knows what those chemicals did to me at that ****inl plastic factory..we made wheel chocks for the navy for their planes on the crusiers.
