Parliament Approves New EU Limits on Workplace Carcinogens

The European Parliament on Tuesday approved a sixth revision of the EU directive on carcinogens, mutagens and reprotoxic substances, updating workplace protections for exposure to several dangerous chemicals. The text was endorsed by 499 votes to 49, with 104 abstentions, after a provisional agreement with the Council.

Substances and safeguards

The revision sets exposure limits for cobalt and inorganic cobalt compounds, polycyclic aromatic hydrocarbons, 1,4-dioxane and isoprene. These substances are used across battery production, steel and metal processing, chemical manufacturing and textiles. The Commission will also assess whether additional limits are needed for substances in welding fumes.

Where exposure cannot be reduced below the set limits, the updated rules clarify provisions for personal protective equipment, including respiratory protection and regular breaks in uncontaminated areas. Employers must provide additional safeguards for firefighters and emergency-service personnel, and appropriate training for workers who may be exposed, including healthcare staff handling hazardous medicinal products.

Implementation timeline

Member states will have two years after the directive enters into force to transpose its provisions, with longer transitional periods for some occupational exposure limits. The Commission estimates the measures could prevent around 1,700 lung cancer cases and 19,000 other illnesses over 40 years.

Why it matters: The vote turns a negotiated agreement into Parliament’s formal position and sets a framework for national implementation. Employers in affected sectors should track the final legal text and country-level transposition deadlines.
