Historically, PIP STF05501 mandated that cages be provided on ladders with a climb length of 20 feet or more. However, modern safety data and OSHA studies indicated that cages do not effectively stop a falling climber; instead, they can often cause additional injuries as a body ricochets down the hoop assembly.
The most significant logic feature to build into your tool is the transition away from cages for taller fixed ladders: Accuris Standards Store Ladders under 24 feet:
Workers step off sideways onto a platform, requiring rigid grab bars stationed directly at the platform's edge. pip stf05501 fixed ladders and cages updated

An interesting paper on the update of (Fixed Ladders and Cages Fabrication Details) centers on the shifting landscape of industrial safety—moving from passive "cage" protection to active Fall Arrest Systems. Historically, PIP STF05501 mandated that cages be provided
: While cages were historically the standard, OSHA no longer considers them sufficient fall protection for new installations over 24 feet. Existing ladders with cages must be retrofitted with a safety system or replaced by November 18, 2036 .
: Rungs must have a minimum load capacity of 250 pounds . They are typically spaced 10 to 14 inches apart and must be at least 16 inches wide . : Cages are required on ladders over 20
The primary focus of recent updates to fixed ladder standards involves the as a primary means of fall protection for ladders taller than 24 feet.
