Edouard Herriot Hospital, composed of 32 blocks (France) is involved in a large modernization program which consisted in the demolition of an entire central medical block names “H”. All the care activities continued in the near blocks.
o Objectives
Demolition can generate fungal spore’s suspension which can be associated with high risk of invasive aspergillosis (IA) in immunocompromised patients 

  • In France, hospital are responsible of the air distributed to patients.
  • Different types of air handling system existed. Their objectives of confort and sanitary secure of aerocontamination depend of the types of unit.
  • In order to be efficient to avoid specific pollution, those systems need to be regularly monitored and maintained.
