About this detail

A roof hatch equipped with an aluminum folding guardrail system at a stair roof opening. The assembly bears on a 1 1/2-inch metal deck supported by structural steel framing, finished with tapered rigid insulation, a 1/2-inch cover board, and a single-ply roofing system. A fixed ladder aligns with the hatch opening, maintaining a regulated step-across distance between 7 inches minimum and 12 inches maximum in accordance with OSHA standards. The folding guardrail system is specific to the stair roof hatch location.
