Best practice is to never assume a firearm is unloaded. Proper equipment would be dummy weapons or similar, in place of "unloaded" firearms.
As I recall, back long long ago when I was a Boy Scout, there was a rifle range at camp, at which we shot "moskeet" small clay pigeons with 22 bird shot. Which, by the way, was tremendous fun. My recollection is that we were taught two basic rules from which one must never deviate. The first is that you never point a gun at anything you do not intend to shoot, and at anyone you do not intend to kill. The second is that you start with the assumption that all guns are always loaded.
That seemed to work pretty well.
