Currently regs are in place to allow carriage of dry ice in appropriate packaging and quantities that will allow the sublimated gas to disperse safely. The amount is reduced eg if we only have one pack working. With this new packaging the sublimation rate is less, so more dry ice can be carried. It’s actually not that new - we’ve been using similar packaging for a while now, mainly for carriage of medical stuff to specific destinations. These regs have been in place for a very long time. One of my NOTOC checks is quantity of dry ice carried.
We don’t use detectors, good question though. But neither do we have detectors for any of the other DG that we carry eg acids, alkalis, solvents. Regs for packaging of DG are really stringent and rigorously applied.
