How safe are our phones?

I just wanted to point you out to this link before I start:

So, how safe do you think out phones are? I’m more concerned about the phones like HTC One which have a completely metal body. If you saw the pictures, the battery had swollen up like a balloon! Do you think plastic phones have this advantage of allowing the battery to expand without causing an explosion or do you think metal body phones would actually help contain it (or cause a bigger explosion with metal flying around)…

While Lithium-ion batteries are almost everywhere, how much thought do manufacturers give to design to incorporate such extreme scenarios?
