What are thermosetting plastics?

Thermosetting plastics harden through a chemical reaction. They include epoxy, polyurethane (with diisocyanates), acrylates and methacrylates, formaldehyde resins and organic acid anhydrides. Before they have cured they can cause allergies, asthma and skin problems - which is why training is required.

Who needs thermosetting plastics training?

Anyone who handles uncured thermosetting plastics, or products containing them, at work - for example:

  • operators, fitters and tradespeople in industry, construction and workshops
  • nail technicians and lash stylists working with gel, acrylic and lash glue
  • dental staff handling composites, bonding agents and other acrylates
  • supervisors who plan and manage such work

Which rules apply?

The Swedish Work Environment Authority's rules on chemical risks are in AFS 2023:10, in force since 1 January 2025. The employer must make sure that anyone who is going to work with thermosetting plastics has been trained in the risks and in how to work safely before the work starts. What the training needs to cover depends on which products are handled and how.

For products containing diisocyanates, the EU REACH requirement also applies: since 24 August 2023, specific training is required before the products are used professionally.

Some work with thermosetting plastics also requires medical checks. That is a separate requirement for the employer and is not part of the training.

How long is the training valid?

AFS 2023:10 sets no fixed validity period for thermosetting plastics training. REACH, however, requires the diisocyanate training to be renewed at least every five years. We therefore recommend renewing the training every five years - and earlier if the work tasks or products change.

What does the training cost?

At BraKem the online training costs, per participant and excluding VAT:
