What may happen to a large container of calcium hypochlorite if it is left to sit in water and muck remaining in a building after fire fighting efforts have ended, but clean-up will not begin for several days? The assumption here is that the plastic container has been compromised in some way by heat of the fire and possibly creating cracks in the base or sides.
