Study chemistry and then consider how materials react. Probably the least likely secondary (that is, can be recharged) battery chemistry to catch fire would be Lead Acid, these days, usually Sealed Led Acid (SLA). As for Sodium batteries, consider what is likely to happen to Sodium if the battery casing ruptures. Ever seen Sodium and water react? Your NiMH batteries aren't especially likely to be a fire hazard. Neither--most likely--would NiCad batteries. None of this means that Lead Acid, NiMH or NiCad are especially healthy to be around is the casing are ruptured. Nickel, Cadmium, and Lead are all toxic in various ways.
