Similar fun would likely be the safety sheet for FOOF (Dioxygen diflouride), a compound that you can't really get to room temperature without said compound tearing itself and it's container apart. I do recall it reacts "vigourosly" (I believe the paper I read on this used those specific words) with Chlorine triflouride at 90K (-180C, -300F).
