Cast iron piping will not melt or burn away in a fire, meaning designers and engineers can avoid the added cost and complexity of adding fire stopping materials to their piping assemblies for every penetration in a building. All that is required to seal a cast iron penetration is some mineral wool batting and fire-resistant caulking around the pipe.
