The pouch types LiFepo4s also vent pretty energetically, that was what a kid at a local robot event had go off in his bit and he got a face full of lithium smoke (And this was like a tiny 2AH 12v pack).

Sure LiFepo4 it's much safer then LiPo but I still wouldn't trust high school kids with them.

That just looks like a bit of toxic smoke... compared to the fiery conflagrations of LiPO I think LiFePO4 is still way safer.
Especially in the SLA "packaging" like in the OP's link, I would find it hard pressed to kill one.
