Re: preparation of styrene kits for painting

I have no doubt what you are saying is correct. The EPA would prohibit the use of Aluminium oxide for an outdoor cleaning where the object and the surface beneath the object are not enclosed by scaffolding covered with an impervious material. The grit being collected and recycled without any offsite migration of the grit or the paint. It was impractical to enclose the Statute of Liberty or a concrete walkway, thus the use of Aluminum Oxide would be prohibited. Your error is in taking this very well defined restriction and extrapolating it to all uses of aluminum oxide. It just isn't so. Using AO in a booth or other enclosure is not restricted in any manner and with proper preparation, it can be used outdoors. Just need to meet all the regulations and jump through all the hoops. Standing in your garage blasting rust off an old lawn mower blade is acceptable as long as the doors and windows are closed. The garage is containment and the only person you are potentially harming is yourself. Just make sure you claen up all the grit. Preferably with a vacuum.
While I do not work for the EPA, the government agency for which I do work is responsible for enforcing the Air Quality regulations locally.

The EPA made the company doing the Statue of Liberty use Baking soda.
Of course you can buy Aluminum Oxide because it is used for things
other than blasting but they do not come into your home and stop you
from hurting yourself. I talk to the company that did our condo
( because I am a director on the board) It can not be used by them.
The directives are out there from the EPA.
