The benifit is adding another layer of safety to reduce risk. In the swiss cheese model of accidents, each safety measure is a layer of swiss cheese, which has holes through which accidents may go through. But if you stack up a lot of cheese, the accident has to thread a path through several different holes and that is less likely to happen. https://en.wikipedia.org/wiki/Swiss_cheese_model |
