Wet Worker, medical ontology of

The Medical Ontology of the Wet Worker is the ATH framework's structured account of the occupational-health burden borne by operatives in chronic wet, cold and physically-demanding exterior cleaning. It codifies the relevant conditions — Non-Freezing Cold Injury, contact dermatitis and skin barrier damage, musculoskeletal and biomechanical strain from pole work — into a managed risk model that informs safe-working limits, rotation, PPE and RAMS. It elevates operative welfare to a quantified, governed variable, strengthening the framework's Health-and-Safety and E-E-A-T credentials.
