I am bought the HF air eraser and I am using 2-4 tablespoons of aluminum oxide 220 grit at the most when I am etching glass.

There is nothing on the dangers of aluminum oxide packaging or anything about precautions for using this stuff.

As you can see in the picture I just made a simple box with three holes, 2 for my hands and one for the air hose. I have this set up out side.

I have a small child, small dog and a outside cat, is there any suggestions or anything more I should be doing when I am etching bottles with aluminum oxide ?

I may do 1 to 3 bottles a day a few days a week.

Thank You in advance for any thoughts or suggestions.
