  • Check the general cleanliness of the building, including checking that the vacuum cleaners are working properly, are regularly emptied, and that their filters are clean.
  • Check that cleaning materials are being properly used and stored.
  • Check the general operation of the heating, ventilation and air-conditioning system. Special attention should be paid to the fresh air supply system.
