I belong to a private club and standard practice is first arriving shooter becomes range safety officer unless he/she defers to another...
Also standard practice when a cease fire is asked for nobody leaves the line until all firearms are unloaded, bolts locked open on bags, rest or bench, preferably with open chamber indicator in place, and all shooters have stepped back from the line...
Only then is a “Line Is Clear” declared and shooters may go downrange to check and replace targets...
Range officer and all shooters are obliged to determine downrange is clear before “Range Is Hot!” command is given so shooting can resume...No gun handling, unpacking or packing up allowed during cease fire...
When my brother, myself and others get some trigger time, one of us is signaled as Master while we are there...
That’s exactly how they do it at the public range in my neck of the woods. I kinda figured that was standard practice everywhere. It should be.
