Gotta disagree there Stumpy.
Argon is inert yes, but it is also narcotic.


Extract from the safety data sheet:

POTENTIAL HEALTH EFFECTS:
Effects of a Single (Acute) Overexposure
Inhalation. Asphyxiant. Effects are due to lack of oxygen. Moderate concentrations may
cause headache, drowsiness, dizziness, excitation, excess salivation, vomiting, and
unconsciousness. Lack of oxygen can kill.

Stumpy, Inert means it won't go bang (unless you damage the bottle) but it's still toxic

I thought Argon was like Helium

Not in itself dangerous, but if it displaces the oxygen you are breathing then you will asphyxiate, and as you are still blowing carbon dioxide off from your lungs in the normal way you will not gasp for breath, just pass out.

I belive Argon is heavier than air

[triker_Chewie]

its not the density, its the fact that its taking up valuable space in yer lungs that is needed for oxygen.
your breathing reflex is triggered by the presence of c02 so if your lungs fill with ANY gas other then air
you will asphyxiate

but if you were laying on the floor it would happen quicker than if you were standing up
