Pump Chamber Access Vent

A narrow rectangular grille set high in the pump chamber's metal walls, secured with flanged bolts and accessible only via collapsible metal ladder. The vent runs horizontally along the chamber's upper tier, its slatted design allowing air circulation while preventing unauthorized entry. Its industrial-grade mesh shows faint scratches from recent use—fresh evidence of Mensch's escape route and the Doctor's subsequent infiltration. The grille's position far above ground level emphasizes the chamber's closed-system design and the difficulty of unobserved egress.
