Diisocyanates are essential chemical compounds used in a variety of industrial processes, particularly in the production of polyurethane products. Although these substances are crucial for many industries, they also pose health hazards if not handled correctly. In this article, we explore what diisocyanates are, the risks associated with them, and why it is legally required to complete training on their safe use to protect both employees and the working environment.
What are diisocyanates?
Diisocyanates are a group of chemicals used as building blocks in the production of polyurethane, a material widely used in everything from insulation and furniture to varnishes and adhesives. Common types of diisocyanates include toluene diisocyanate (TDI), methylene diphenyl diisocyanate (MDI), and hexamethylene diisocyanate (HDI).
These compounds are highly reactive and can cause serious health problems if inhaled or come into contact with the skin. Exposure to diisocyanates can lead to respiratory problems, skin irritation, and in the worst case, the development of occupational asthma. Therefore, it is essential to understand how to handle these substances safely.
EU requirements and mandatory training
From August 24, 2023, the EU has introduced requirements through the REACH Regulation (Annex XVII, entry 74) that all persons working with diisocyanates in concentrations above 0.1% by weight must undergo documented training in safe use. This requirement applies throughout the EU/EEA area, including Norway.
The training is divided into three levels based on the degree of exposure:
- Basic training – For anyone who may come into contact with diisocyanates
- Intermediate training – For those who regularly work with products containing diisocyanates
- Advanced training – For those who perform spraying or other tasks with a high risk of exposure
Training must be renewed every five years to ensure knowledge remains up to date.
Who is required to take a diisocyanate course?
The requirement is broad and affects many industries and occupational groups:
- Painters and varnishers – Working with polyurethane-based varnishes and paints
- Insulation installers – Spraying or installing PUR foam and insulation
- Car workshops – Painting and repairs with polyurethane products
- Furniture manufacturers – Adhesive and foam production
- Construction and building – Sealing, bonding, and insulating with PUR products
- Industrial workers – Anyone handling products with diisocyanates above the limit value
Employers are responsible for ensuring that all affected employees have completed approved training. It is not sufficient for the company to have general HSE training – specific training in diisocyanates is a separate requirement.
Why is safe use of diisocyanates training important?
1. Prevention of health hazards
Exposure to diisocyanates can lead to serious health problems, including allergic reactions and chronic respiratory diseases. Through safe use training, employees learn how to protect themselves, including the use of personal protective equipment and correct handling of chemicals to minimize risk.
2. Compliance with legal requirements
The EU requirement is clear: without documented training, it is forbidden to work with diisocyanates. Completing courses and certification is therefore not only important for health and safety, but also to ensure that your company complies with applicable laws and regulations.
3. Increased awareness and workplace safety
The courses provide workers with increased understanding of the risks of diisocyanates, which can lead to a safer workplace. Companies that invest in training show that they take HSE seriously, which improves the working environment and reduces sick leave.
4. Reduced costs for the company
By preventing health injuries through proper training, the company can reduce costs associated with sick leave, medical treatments, and potential legal consequences due to non-compliance with HSE requirements.
Consequences of insufficient training
Companies that fail to ensure employees have completed mandatory diisocyanate training risk:
- Prohibition of use – According to regulations, it is illegal to use diisocyanates without documented training
- Supervisory reactions – The Norwegian Labour Inspection Authority can issue orders, fines for violations, and work stoppages
- Liability for damages – In case of health injuries, the company may be held liable for damages if training has not been completed
- Insurance problems – Lack of documentation can affect coverage for occupational diseases
What does the course cover?
Training in the safe use of diisocyanates covers important topics such as:
- Identification of risk factors when working with diisocyanates
- Safe handling and storage of chemicals
- Use of personal protective equipment (PPE) such as respirators and gloves
- Measures in case of accidents and first aid
- Legal requirements and documentation – What the REACH Regulation requires
