It'll allow states to race to the bottom in worker safety, which I suppose is the idea. It might also make compliance overall more expensive by creating a fragmented patchwork of regulations and practices, which increases complexity. Look at the effect of different states having different fuel formulation requirements on the oil refining industry. A lot of the cost of regulatory compliance comes from complexity, fragmentation, and cognitive load. Simple uniform regulations are cheaper and easier.
