Duomo Operations – Safety & Sustainability

Daily Rhythm

• Visual checks, stone condition logging and access route inspections.
• Scheduled cleaning to slow soiling; consolidation where micro‑cracking appears.

Safety Layers

• Controlled visitor flows on narrow stairs; weather thresholds for rooftop access.
• Staff trained for assisted movement on the terraces and in the nave.

Sustainability

• Marble care extends lifespan; LED lighting and careful HVAC reduce energy in the museum and crypt areas.
