Hi All: While parusing the ATF web page to look for regulations that would apply to liquid O2 - C3H8, and O2 - Kero, I found this ...
http://www.atf.gov/forms/notices/04-7020.pdf Under the "L" listing, liquid O2 'explosives' is listed as a single entry. Also under "P" is listed 'Peroxide based explosive mixtures'. So does this mean that a liquid rocket engine using LO2 or H2O2 is considered an explosive? If so than a prop flow greater than 62.5g falls under regulation and permitting requiremnets? What is the experience of the folks who build and test hardware out there? Note, the form says the list is not all inclusive. I guess that way they can say you fall under regulations for anything. It looks like one out might be to transport gaseous O2 and liquify it on site with LN2. There seems to be a rather large exemption for producing 'explosives' on your own property. -- Andrew _______________________________________________ ERPS-list mailing list [EMAIL PROTECTED] http://lists.erps.org/mailman/listinfo/erps-list
