Indoor air quality: a key issue for schools

Since 1 January 2018, indoor air quality monitoring has been mandatory in France in all buildings that are open to children under the age of 6. And since 1 January 2020, such monitoring has been made mandatory for all secondary schools, colleges and leisure centres. The regulations are moving towards making it mandatory to monitor indoor air quality regularly in all buildings open to the public. The substances to be monitored are formaldehyde, benzene and carbon dioxide (CO2). Decrees No. 2011-1728 of 02/12/2011 and No. 2012-14 of 5 January 2012.

On average, children spend 90% of their time indoors (in classrooms, at home, when travelling, in sports centres, etc. Note that indoor air can be 8 to 10 times more polluted than outdoor air.

  • 40% of environment-related diseases affect children under 5.
  • In France, 1 out of 10 children suffer from asthma.

Poor air quality causes many symptoms (fatigue, irritation of the eyes, nose and throat, hyperactivity, etc.) experienced by both educational professionals and children.

The issues for your profession:

  • Headaches
  • Fatigue
  • Irritations
  • Hyperactivity
  • Difficulty concentrating
  • Respiratory allergies

Sources of pollution in schools

The indoor air in schools can contain many different pollutants, some of which are organic (bacteria, viruses, dust mites, etc.), others chemical (formaldehyde, benzene, adhesives, paint, etc.) and still others gas (carbon dioxide, etc.). The pollutants come from building and decorating materials, (new) furniture, cleaning products and disinfectants, activities carried out with the children, etc.

  • Fine particles
  • Stubborn odours
  • VOCs (adhesives, varnish, paint, etc.)
  • CO2
  • Bacteria, viruses

Occupants (staff and students) breathe this polluted air every day, which is why it is imperative to improve indoor air quality in schools.

and health for users

Improving indoor air quality helps to prevent the spread of epidemics by eradicating bacteria and viruses present in the air. Purifying the air in your school also ensures that you provide the best possible conditions for children, including any said to be particularly sensitive to air quality (allergic, asthmatic, etc.). Last but not least, by giving your staff clean air every day, you will retain them more easily and reduce absenteeism (during winter epidemics for example).
