Can OSB plywood get wet?

The OSB floors should be swept clean each day after work concludes..
Should I use OSB or plywood for roof?
OSB takes longer than plywood to get saturated, but also takes much longer to dry out. When used as roof sheathing, this tendency to hold moisture means it will degrade faster than plywood when exposed to chronic leaks.

How can you tell the difference between plywood and OSB?
OSB boasts a more consistent density. While a sheet of plywood might be 5 to 7 plies thick, a sheet of OSB is made from as many as 50 strand layers packed and compressed into the same thickness. There’s no equivalent of the weak spots that can be left in plywood when knotholes in adjacent plies overlap.
