Does any one know how toxic Purple Heart wood dust is?  I know breathing it is, and I plan to wear a mask made just for toxic dust, but what about covering my arms and hands?  What about my face?  I plan to do my husbands purple heart medal on this purple heart wood I already received.  I will close the shop door, close off the kitty door, open the windows and scroll it all at once while he's gone to his uncle's for a couple of weeks.  It is 11:00 here and 76 degrees (F)! I also plan on cleaning up all the dust that I can.  Is there anything else about this wood I need to know?  I know it's very hard and I have blades set aside just for it.  I will finish it with non-yellowing polycrylic gloss clear coat.  Thank you for your help!
