Yeah, here in the US almost every state has “at will” employment, so any protections could really be circumvented by just firing a worker for whatever other reason (or no reason at all) they want. Hopefully labor has it better in the land down under.

I was a researcher for around twenty years and almost passed out leaning over an LN2 tank like an idiot looking for my samples once. No pain, just felt some tingling and rapidly fading consciousness. There was still a good amount of oxygen in the room since the alarms never went off. Just glad I started to fall backwards instead of into the tank.

I’ve also experienced nitrogen narcosis while deep diving, and that actually felt good.

For an AR-15 you can just use an AR Maglock and Kingpin, then it’s just a button press to very slightly separate the upper and lower receiver, allowing for magazine ejection. It’s almost as fast to change magazines as in other states.

There’s also zero chance a criminal would follow these laws. It takes maybe a minute to disable a maglock and swap on whatever stock you want. “Freedom Week” or old 30 round mags are prevalent as well.
