I don’t think you can do it with beer. The yeast used dies from the alcohol they produce. I’m sure there is nasty bacteria that can survive in concentrations of alcohol above what yeast can.
You could make vodka, or moonshine, but that requires distillation and is a more advanced tech.
Soap (made from animal fat) and water should do fine for your hands. Use a fire to disinfect any tools before you use them (let them cool off first). That should majorly help with survival.
make very strong beer. ferment longer
