Gun safety courses actually discuss (at length, at least in my state) about how even if you’ve just got the gun on your desk next to you, but it’s loaded, it needs to be pointed in a safe direction. Even doing dry fire exercises (practicing, say, holstering/unholstering with the gun unloaded and the magazine removed entirely), you’re supposed to point the gun down at where the floor meets the wall to minimize any chance of anyone being hurt by an accident discharge.

Basically, you’re supposed to follow the same rules as if the gun was loaded and you’re holding it: don’t point it at anything you aren’t willing to destroy, and know both what it is pointed at and what lies beyond that.

I personally wouldn’t want a doctor on their 23rd hour of work to try to unload a firearm in a crowded and hectic ER, and don’t have the answer to how to handle this situation, but I’m not a medical professional so…
