Confirm the private residence elevator door-gap safety requirement in ASME A17.1 Section 5.3 and check for related CPSC recalls

Steps

1. Confirm the requirement, present from the 2016 edition onward, that the space between a closed hoistway landing door and the car gate/door must reject a 4-inch-diameter ball at all points, addressing a documented child entrapment hazard
2. Confirm the related sill-to-door-edge distance limit (no more than 3/4 inch) from the same safety-update context
3. Check the equipment's original install/edition-compliance date against the jurisdiction's adopted A17.1 edition to see whether the gap requirement applies retroactively there (via a locally adopted retrofit rule) or only to new installations
4. Search the U.S. Consumer Product Safety Commission's own recall database (cpsc.gov) directly for the specific manufacturer/model in question rather than relying on secondary industry summaries, since recall scope and remedy (e.g., space guards) are manufacturer- and model-specific
5. Where a gap-guard retrofit is warranted, confirm with a licensed residential elevator contractor that the proposed fix meets the current code's ball-rejection and sill-distance criteria
