They can be if you store them in something like an ammo box. If they "go off" in the sealed box the pressure builds, the reaction rate increases exponentially, and voila... shrapnel time. There's a video out there showing the results.
Most people recommend storing them in nomex/kevlar "cell bags". I keep mine, bagged, in an unused/unplugged oven! If one goes off, hopefully the flames won't spread to the rest of the property and the hinged oven door allows pressure to escape.
Hobby RC packs are one of the most dangerous type of rechargeable lithium cells out there... even from "reputable" sources and brands. A local hobby shop twice had brand new name brand packs sitting on the shelf go off. A friend of mine had the same thing happen carrying a just purchased pack home in his car.
