Thanks for the info! After cleaning up should I avoid the area for about 24 hours or longer (and/or hose it down), since it's outdoors?
I'll pickup a suit. I'll be using a 3M 2097 filters with a 3M6300 Mask https://www.amazon.com/gp/product/B00328IAO0/ref=oh_aui_detailpage_o03_s00?ie=UTF8&psc=1
This does filter dust but is designed more for vapors (paint fumes). The mask is great and you can replace the cartridges with particulate filters (for dust/debris) like these: https://www.amazon.com/3M-2097-Particulate-Filter-Organic/dp/B00328IAO0
I just bought and received P100 filters last week.
Amazon has 10 packs of 3M N95's available for delivery by the 15th.
...and McMasterCarr has N99's in-stock.
There were in impossible-to-get supply in March. It's not March anymore.
I'm still seeing some on Amazon. https://smile.amazon.com/dp/B00328IAO0
You can get them on amazon or almost any local paint or hardware store.

These filters will work, but be aware of the fact that if your mask smashes against it you won't be able to breathe well.
