Working with Bone

How cautious do I need to be when working with bone? Before I start I'm going to pick up a decent respirator, but what about the work area itself.
My workbench is out the back of my house and when I'm not working there my wife and kids use the area. I normally vacumme the bench and sweep the floor but is that enough when dealing with bone.
Thanks

If you're outdoors you are probably okay. Wouldn't worry too much about the wife though. :w

In my shop, I open my doors, put a fan in the doorway for exhaust and dust the whole thing with a leaf blower. I don't know if this makes it safer or healthier, but it does ease up on that delightful scent of freshly ground bone
