Blueprint: Ultraviolet Disinfection for Low-Resource Clinics — Installation and Implementation Specification

Installation and implementation specification for ultraviolet disinfection in a reference low-resource clinic room: two louvred 254 nm upper-room fixtures delivering 12.1 equivalent air changes per hour for tuberculosis at $0.88 per room per day, an optional four-fixture far-UVC 222 nm whole-room system capped by the named exposure standard (1.02 eACH under ICNIRP, 7.16 eACH under ACGIH), and a two-position 254 nm surface terminal-disinfection cycle for direct-line surfaces only, with required equipment, installation, commissioning by radiometer measurement, operating procedures, failure modes, maintenance, safety limits, and costs. DESIGN BLUEPRINT — SIMULATED, NOT MEASURED — NOT BUILT, NOT CLINICALLY TESTED. Blueprint for the specification published as DOI 10.5281/zenodo.24108585.
