Air Cleaners

On August 24, 2023, new EU regulations regarding the use of diisocyanates came into force. According to the new regulations, diisocyanates may no longer be used industrially or commercially either as a substance or as a component of other substances and mixtures if their concentration individually and in combination is 0.1% by weight or more, unless the user has previously carried out training in safe use of diisocyanates.

In addition, if the product is covered by the new requirements, the manufacturing company must have the following statement printed on the label: “As from 24 August 2023 adequate training is required before industrial or professional use”.

What are diisocyanates or isocyanates?

Isocyanates or diisocyanates (commonly known as polyurethane or PU products) are the main materials for the production of polyurethanes. Diisocyanates are found, for example, in foams, glues, paints, coatings and sealants. An example that many can relate to is PU foam, which is created by foaming with a spray can. Whether a product contains diisocyanates can be checked in the safety data sheet.

Why is a limitation necessary?

The reason for the restrictions is above all the increase in work-related illnesses among people who handle diisocyanates. Isocyanates can, among other things, lead to respiratory diseases, including severe asthma. According to data from the Commission’s regulation, approximately 5,000 people develop work-related asthma each year due to exposure to diisocyanates.

Isocyanates are absorbed by inhaling gases, vapors, aerosols and dust particles containing isocyanates. Isocyanates sometimes cause sensitization, in the form of a type I allergy. Research has also shown that exposure to isocyanates can alter and destroy cell membranes in the human body.

Technical protective measures

In addition to training, technical solutions can help companies meet the limit values and thus ensure a healthier workplace.
