Col. Jeff Cooper, an influential figure in modern firearms training, formalized and popularized "Four Rules" of safe firearm handling. No accident with firearms has ever occurred without violating at least one of these rules:
Please be aware of these rules at all times when handling firearms.
Guns are always Loaded, everywhere, all the time
Be sure of your target and what is beyond it
Never let the muzzle cover anything you are not willing to destroy
Keep your finger off the trigger until your sights are on the target
From the perspective of the actual target system, there are several safety tips which everyone should observe.
Range customers should NEVER be down range.
Range employees should always disconnect the power from the rear of the target system prior to performing any maintenance on the target system.
No one should EVER look directly at a laser. Doing so could adversely affect your eyesight. When shooting the Plinker Target System, each target is illuminated by a laser beam. The image you see, as a shooter is the laser beam being reflected off of the steel target. You are not looking directly at a laser beam.
