Xenon danger

Hi. Based on the article's history, it appears that you added the following text to the xenon article back on April 4, 2005:

A complicating danger is that Xenon is heavier than air, and in fact too heavy for the lungs to expel unassisted. After inhaling Xenon, it is necessary to bend over completely at the waste to allow the excess gas to "spill" out of the body. If a person passes out after suspected heavy gas inhalation, first aid includes lifting the person by the ankles into an upside-down position to allow the gas to spill out of the lungs.

Do you happen to recall the source you used for this? I'd appreciate knowing as I'm trying to cite it for the article. (Thus far I haven't had any success finding a suitable source.) Thank you. — RJH (talk) 17:36, 11 October 2007 (UTC)[reply]
