Post-incident audit of an elapid range
A regional zoological park retained the practice following a near-miss during a routine cleaning shift. Audit identified a gasket tolerance drift of 3 mm on four of eleven enclosures, traced to a change in the adhesive used by a sub-contracted fabricator. Corrective work was specified within twenty-eight days, including a shift-level rehearsal of the revised lockout procedure.
Outcome: Collection returned to full rotation. No incidents in the twenty-two months since.
