I want to know the effect of breathing Anodize and Chemfilm particles. The part I work with is made of aluminum sand casting which gets anodized and chemfilmed after being machined. I have to hand polish the inside of the part with sand paper. So in total i sand about .0015 of the Anodize. I do not use a face mask cause I have problems breathing with it. I blow the dust with a air hose making all the particles fly into the air. I end up getting it all over my face, arms, and hair. I noticed that my face and neck started breaking out in a rash. Ive never been told the effects of these chemicles and just wanted a helpful understanding of what Im working with. Also sometimes I touch up some parts with Chemfilm. Sometimes it gets alittle messy and I end up getting the chemfilm all over my hands. Is this harmful?
