Some details of the INF interventions:

On 18th March, I went in the Cleaning Lab (where is the tank of the ultrapure water) to check the leak of water reported by M. Perciballi. Once there I contacted D. Soldani for instructions. He instructed me to close all 5 valves in order to stop the leak. ~ 19.30 UTC I did it.
