Just to be clear, I am NOT advocating using firearms that contain live ammunition during any sort of training, outside live fire drills.
That said, one simple step as part of organizing a class to reduce the risk of accidental/negligent shootings from happening is to clear and inspect every firearm prior to entering the classroom.
This is why you make them sign a hold harmless waiver. CYA like the ranges around here do.
There are two kinds of people in this world:
Those that have had an ND, and those that will.
The idea is to ensure that when that unfortunate occurrence comes to pass that no one is hurt because of it; otherwise there would be only 1 safety rule: don’t fire the gun except when you want to.
Guns are dangerous. Humans make mistakes. Life is risk.
Approach the world accordingly.
Well said F2S!
For the Internet’s sake I’ll post 4 rules everyone’s heard:
1 All guns are always loaded.
2 Never let the muzzle cover anything you are not willing to destroy.
3 Keep your finger off the trigger until your sights are on the target.
4 Be sure of your target and what is beyond it.
Obviously this wouldn’t have happened if 1, 2, or 3 were followed.
