Abstract: A safety parapet system for securement to the wall surfaces of building structures and which can be disposed on uneven ground that may surround the building structures includes at least two stanchions located adjacent the wall structure with each stanchion capable of receiving a drop-in safety rail post that is telescopically adjustable along the length of the stanchion for locking into place with the safety rail posts being independently adjustable on the stanchions so that a walkway can be supported in a horizontal disposition on laterally extending members of each safety rail post whether the safety parapet system is disposed on level or uneven ground. An optional handrail can be mounted to the safety rail posts for use if the worker is located six feet or more above the ground surface.
