>> Isn’t balloon helium mixed with oxygen so that children don’t suffocate inhaling it? > Nope. The stuff you can get from party stores (in the US, anyway) definitely isn't; more than one person that I have heard of has committed suicide with it. Apparently, ballon helium is now often mixed with air in the US: Where can a person obtain ‘pure’ helium? http://assisted-dying.org/blog/2015/07/11/where-can-a-person-obtain-pure-helium/ http://assisted-dying.org/blog/2015/07/11/where-can-a-person... Unfortunately I missed the warning about the change in helium tanks that will now include oxygen. Ballon Time FAQ https://www.balloontime.com/contact-us/faqs/ https://www.balloontime.com/contact-us/faqs/ Our helium is rated from 98-99.99 percent pure. However, due to global helium supply issues, we are now mixing helium with air. All tanks will have 80 percent or more helium.
