i know at the plant i work at, if you work on or near the dock , you must wear a life jacket/vest the entire time. Or on the Gyp stack (basically a very tall lined pond). But at the height of that bridge, i am not sure someone would survive that fall.
I feel like that’s more reason to wear it. If the fall doesn’t kill you, it may seriously injure you to the point you can’t stay afloat.
