I think we need more detailed information on this. How big was the explosion? Was anyone hurt? How many reeds were lost in the mayhem?
Seriously though, I have had spools blow up in my hands, too. Not, however, since I started using the FF nylon sold by RDG Woodwinds (not a solicitation). It is sold on a double-ended white plastic spool (165 yds.), with a simple black-and-white label which states "Made in USA." The spool seems more than sturdy enough to withstand my death-grip-pull-til-it-almost-pops technique. I've gone through at least a half dozen spools with no casualties (so far).
Good luck, and don't forget to wear your flack jacket -- just in case!
