I'm seriously considering at LEAST a mask and safety glasses...
The thing is too, with this habanero powder...it don't wash off!!! I've literally washed my hands with soap (ok, maybe not as good as I coulda, but still, WITH SOAP) and then rubbed my eyes and it's burned me.
Heh. Once upon a time dummy me sliced up some jalapeno's for a recipe. Washed the dishes by hand, took a shower, washed my hair, etc. The upshot is that I had my hands in all kinds of soapy water after the pepper and took out my contacts at the end of the day. Bad move. My eyes burned like fire when I put those things in the next day.
