Good that you are thinking of safety while spending time on your project.
I keep plenty of eye wear, gloves, jack stands, extinguishers, band aids, telephone, etc. handy.
I stored my Plymouth, and Dodge using 4 auto jack stands, under the frame. I placed several cookie sheets with cat litter, on a large plastic sheet, under the car to soak up moisture, and any oil/grease drips. With the wheels off the car, I could work on brakes, etc. easy when ever I had the time. My brake drums had high spots, probably from sitting too long,so had them shaved.
I always use jack stands when ever I jack a car up, even for a short time. If a jack seal pops, the car come down in an instant.
