In order to practice the safest lightsaber fighting styles, follow the S.A.B.E.R.S acronym.

S is for safety. Always ensure your saber is secure before forgoing a fight. Check for loose blades, grips, and straps.

A stands for awareness. Get to know your surrounding area and become aware of objects that can obscure your fight. There's nothing worse than accidentally hitting an unseen item and damaging your blade.

B is for batteries. Keep a new supply of batteries with you anytime you leave for a battle or convention. You wouldn't want a lightless saber!

E stands for experience. No matter what saber you own, the experience you have with it will be incredible.  Get acquainted with your saber and learn its many quirks and elements. The more experience you have with your saber, the better your performance will be.

R is for restraint. Don't aimlessly swing your saber around uncontrollably. Additionally, random dueling can result in injury. Know how much your saber can withhold and act accordingly.

Lastly,

S stands for share. Share the experience of owning a lightsaber and the happiness it brings to you and those around you. Inspire people to wield the lightsaber force.
