I was mowing a property for someone that had ancient dried up fiberglass insulation for a dishwasher laying around. I accidently backed over it and it went everywhere. I quickly place my shirt over my face and stopped the mower. The fiberglass insulation had been dried in the sun for a long time and was breaking up and falling to pieces. Should I go to the doctor to get screened for cancer or lung failure? I’m freaking out!
