Never point your gun at anything you do not intend to shoot. This is particularly important when loading or unloading a firearm. In the event of an accidental discharge, no injury can occur as long as the muzzle is pointing in a safe direction. Continually check the area for other users.
A safe direction means a direction in which a bullet cannot possibly strike anyone, taking into account possible ricochets and the fact that bullets can penetrate walls and ceilings. The safe direction may be “up” on some occasions or “down” on others, but never at anything not intended as a target. Even when “dry firing” with an unloaded gun, you should never point the gun at an unsafe target.
Make it a habit to know exactly where the muzzle of your gun is pointing at all times, and be sure that you are in control of the direction the muzzle is pointing, even if you fall or stumble. This is your responsibility, and only you can control it.
