The Royal Decree of 2 May 2019 amends the Code on well-being at work with regard to indoor air quality, adding the definition of “work space”, i. e. the space in which a workstation is located. It also modifies the articles concerning the ventilation of workplaces.
The general principle is that workers must enjoy good indoor air quality. Previously, only the criterion of “sufficient fresh air” counted. The employer is now required to carry out a risk analysis of indoor air quality and take into account the different sources of pollution: presence and physical activity of persons; presence of products and materials in the workplace; maintenance, repair and cleaning of the workplace and air quality provided by infiltration and ventilation, pollution and operation of ventilation, air treatment and heating systems.
The employer must take the necessary technical and/or organisational measures to ensure that the concentration of CO2 in the workplace is generally less than 900 ppm.
The basic rules contained in the Royal Decree of 2 May 2019 will be specified in a practical directive to be published on the website of the SPF Employment, Labour and Social Dialogue.
