Does bacteria walk, ie move along a table or am i safe if i keep 1 ft away from the danger zone?

Depends what you mean...

If you have a petri dish of pathogenic bacteria, then as long as it is covered you are probably ok, but you should wear gloves while handling it just to be safe.

Many bacteria can produce spores, which can become airborne, so if the lid is off the dish, they can easily "escape".

Bacteria can swim in liquids, even a very thing film of liquid on a surface, but they don't "walk" as such.

Remember that most bacteria are harmless, or even beneficial. Your skin is covered in bacteria. Your intestines contain trillions of bacteria. You have more bacterial cells in/on your body than you have cells of your own, and there are more E. coli in your intestines than there are people in the world.
