nitrogen is about a 1/3 of the price of helium last i checked
if you get in a accident that is bad enough to break the valve off...which is kinda slim
this could be a big debate but i think the bottle has to gain speed to cause problems
if the bottle is held in with proper brackets that are not made out of wood,sheetmetal,elastic bands, etc....the bottle shouldnt be able to launch itself
now let it sit on the ground stand in front of it while your buddy knock the valve off lol and try to catch it and then its going to be a different story lol
also they make different styles of valve/regulator protector caps that are available online or at your local bottle shop
