Always follow the fundamental rules of firearm safety: Treat every firearm as if it were loaded. Never point a firearm at anything you are not willing to destroy. Keep your finger off the trigger until your sights are on the target. Know your target and what is beyond it. Ensure your firearm is completely unloaded and no live ammunition is in your training area before starting practice.
