Making outline

Assemble duty-selected eye/face and contact barriers, fixed splash separation and independent emergency rinse interface
Detailed procedure and acceptance remain unresearched.

What remains unresolved

Complete inventory, source-supported recipe, independent acceptance, caller demands, stock/loss and availability remain unreviewed.
Current memory-first method needs source and compatibility review.
