Found some drywall dust behind my fridge. It’s been there a year. It’s about 1/3 cup of dust. I already cleaned it but my only concern is there’s a fan behind the fridge that blows air behind the fridge. My fridge is in in a cut out space, with a wall on one side and a counter on the other side and cabinets above. The dust was there when I pulled the fridge out, seems like it didn’t go anywhere but wondering if a little has been flowing in the house. Read drywall dust has silica in it and your not supposed to breathe this. Is this a huge exposure since it’s been back there a year? Thank you
