Fall protection is now required for fixed ladders extending more than 24 feet above a lower level.
Is the climb over 24 feet? If yes, specify a cable-guided or rigid-rail fall arrest system instead of a cage.
PIP STF05501: Understanding the Updated Standards for Fixed Ladders and Cages
The Process Industry Practices ( ) document , which covers Fixed Ladders and Cages Fabrication Details underwent a major revision in

"Cages shall not be specified for new fixed ladder installations. Cages are considered a means of fall containment, not fall arrest, and do not meet the intent of modern fall protection hierarchy."
Fixed ladders installed or replaced after November 19, 2018, that extend more than 24 feet above a lower level must use a personal fall arrest system (PFAS) or a ladder safety system (e.g., vertical cable or rail), not just a cage.
All material for ladders and cages must be ASTM A36/A36M unless specified otherwise. Fall protection is now required for fixed ladders
The release of the updated PIP STF05501 standard for fixed ladders and cages marks a significant and necessary evolution in industrial safety specifications. As safety protocols continue to shift toward modern fall protection requirements, this updated standard provides a vital roadmap for engineers and safety managers looking to align with current regulatory landscapes.
Understanding the functional difference between the old standard (cages) and the new updated PIP standard (LSS) is vital for facility safety. Traditional Ladder Cages (Old PIP) Ladder Safety Systems / PFAS (Updated PIP) Encloses the climbing space to contain a falling worker.
: For existing ladders with cages, assess the condition and plan for their eventual replacement by November 18, 2036 .
The PIP STF05501 practice details the construction specifications required to provide safe, regular operational access and egress in highly volatile process industry facilities. Core Fabrication Elements PIP STF05501: Understanding the Updated Standards for Fixed
Grandfathered for old installs; banned for new builds >24 ft.
Requires the side rails to flare out and extend at least 42 inches above the top landing to serve as built-in handholds.
The shift from 1910.27 to 1910.28, and the transition of standards like PIP STF05501, represent a major evolution in workplace safety philosophy—moving from passive fall containment (cages) to active fall arrest (PFAS/LSS). While the recent proposal to remove the 2036 deadline offers operational flexibility, it does not change the fundamental legal requirement to use modern, approved fall protection systems on new fixed ladders over 24 feet.
Are you planning to or retrofit safety cables inside them?
The updated standard includes several key changes, which are summarized below:
