Apparatus and method for providing a guard rail adjacent an access aperture extending through a floor surface, such as in an attic space of a residential structure. A guard rail assembly includes a top rail portion which extends adjacent at least one side of the access aperture to provide a guard rail. An angled portion extends at a non-orthogonal angle to provide a hand grip surface for a user passing through the access aperture. A front leg segment supports an end of the angled portion opposite the top rail portion. Preferably, a rear leg segment supports the top rail portion to form a first side rail assembly. A second, nominally identical side rail assembly adjoins the first side rail assembly to form a substantially u-shaped top rail surface that surrounds the access aperture on three sides. The guard rail assembly is further preferably adjustable to accommodate different access aperture dimensions.
