Never forget that a gun has the potential to produce serious injury or
death in a single instant of carelessness. Make safe gun handling a
habit to be followed at all times. After you determine that a gun is
unloaded, continue to handle it as though it were loaded.

In selecting a safe directions, you must also take into consideration

that bullets can penetrate walls, ceilings, floors and windows.
you finger out of a gun's trigger guard and off the trigger until you
have aligned the gun's sights on a safe target and you have made the
decision to fire! By keeping your finger completely
outside the trigger guard until you have aimed at the target, you
guarantee that any shots you will fire will go safely in the direction
of your intended target.
Always be certain that your target and the surrounding area are safe before firing!
