A climbing safety assembly for securing a ladder to a stanchion includes a plate that may abut a stanchion so the plate extends laterally away from the stanchion. The plate selectively engages a ladder. The ladder is retained proximate the stanchion so the ladder may be safely climbed by a user. A hook is operationally coupled to the plate. The hook may selectively engage the stanchion so the hook retains the plate on the stanchion. A belt is operationally coupled to the plate. The belt may be extendable around the stanchion so the plate is retained on the stanchion.
