In the kitchen, definitely, I have to soap where there's a sink, totally finicky about any spills or drips. I mix lye in the sink, and recycle newspapers to cover all surfaces. Safety precautions latex gloves, socks, shoes, I wear glasses so don't bother with goggles, a minimum of shorts and t-shirt, no long sleeves (somehow I always get soap batter on those, I think easier to rinse bare skin when I feel any touch of lye). Religious about cleanup after soaping -- wipe floors, all counters and workspaces within several feet, rinse and soak pots and utensils so all that's apparent is a little residue which soaks overnight in Dawn.
