Titanium dioxide helps clean up ambulances in Italian city

New ambulances in the Italian city of L’Aquila have been fitted with an interior lining containing titanium dioxide to clean surfaces.

The titanium dioxide has specifically been inserted into the ambulances’ passenger cab lining for this purpose, removing pollutants and inactive microorganisms from surfaces.

When the chemical comes into contact with light and air an oxidation process occurs, leading to the rapid decomposition of potential harmful dirt present in ambulances, reducing the risk to patients.

Using a particular grade of titanium dioxide in this way means it acts as a photocatalyst when exposed to UV light. An electrochemical reaction occurs producing free radicals which decompose pollutants.

The lining has been fitted in seven new ambulances, funded by L’Aquila’s local health authority, including an ambulance specifically reserved for neonatal transport.
