It's also depending on the frequency of the AC voltage
if the frequency is close to man's avarage heart beat rate (60 a 70 Hz) than the chance it will disturb the heart beat is pretty big and more lethal than just a DC voltage with the same values
of course it starts all about 63V or higher (that's what I learned on school )
i normaly say every thing lower than 48 Volt is considered safe (not lethal) you still can burn your self and have a not so good time if you are a conductor for many amps at that voltage
