Is there any Static Hazard?
The output of the top gate will be A. The output of the middle gate will be 1 (as it has a zero at one input). The output of the bottom gate will be 'A (inverse of A). The right hand gate will always have a zero going in so will always have a 1 going out. As A changes, if the right hand gate responds to the high going transition first it will glitch low, as it will briefly see 3 1's at its inputs.

The following chart shows the logic signals as A goes 0 to 1 to 0
