Caution!

The chemical etching process entails the use of corresive etching solutions that can be hazardous if the appropriate precautions are not taken!!

You must carefully read, understand, and follow all manufacturer usage instructions and safety protocols.
Always wear safety goggles, neoprene gloves, and a protective lab coat. Do not wear loose or baggy clothing or jewelry. Wear long pants and full shoes (no sandals or other open shoes).
You must dispose of used or excess etching chemicals properly. NEVER POUR ETCHING CHEMICALS INTO ANY SINK OR TOILET. Follow MSDS instructions and proper university protocol when disposing of chemicals.
