  1. Lösemittelimmissionen in einem Schulgebäude nach Einsatz von Bautenschutzmittel.

    Article - En allemand

    Traduction en anglais : Solvent-immissions in a school building after the application of a moisture repellent.

    A wall of a school building was treated with a moisture repellent containing a silicone resin and white spirit.

    In the temporal connection with this a child experienced an exacerbation of its bronchial asthma.

    Some weeks after the second application the users of the rooms complained about unpleasant odor and discomfort.

    As shown by analysis the white spirit containing aliphatic and aromatic hydrocarbons diffused through the 50 cm thick stone wall into the classrooms.

    Due to the considerable concentration of the pollutant a part of the building could not be used any longer.

    In Germany no guideline values exist for white spirit or any mixtures of hydrocarbons in indoor air for non-occupational workplaces.

    For the reopening of the rooms a target value of 300 mug VOC/m3 was set.

    The incident shows that building materials can cause health problems and discomfort even if instructions of application are followed.
