EU boosts worker chemical protections
The European Parliament's Employment and Social Affairs committee adopted a position to strengthen protections for workers exposed to dangerous substances, updating health and safety rules linked to the industrial transition. The move frames worker exposure as a regulatory issue alongside emissions and competitiveness. (europarl.europa.eu)
A European Parliament committee voted on April 15 to tighten European Union rules for workers exposed to hazardous chemicals at work. (europarl.europa.eu) The vote in the Employment and Social Affairs committee covered the sixth revision of Directive 2004/37/EC, the European Union law on carcinogens, mutagens and reprotoxic substances at work. The file’s rapporteur is Liesbet Sommen of Belgium from the European People’s Party. (europarl.europa.eu 1) (europarl.europa.eu 2) The European Commission proposed the update on July 18, 2025, with new exposure limits for cobalt and inorganic cobalt compounds, polycyclic aromatic hydrocarbons, and 1,4-dioxane, and with welding fumes added to the directive’s scope. The Commission said the package could prevent about 1,700 lung cancer cases and 19,000 other serious illnesses over 40 years. (employment-social-affairs.ec.europa.eu) (europarl.europa.eu) The law works by setting workplace exposure caps, measured in milligrams per cubic meter of air, for substances linked to cancer, fertility harm, or other long-term disease. Welding fumes are not one chemical but a mix that can contain carcinogens such as chromium, nickel and cadmium compounds. (employment-social-affairs.ec.europa.eu) The substances in this round sit inside industries the European Union is trying to expand, including battery production, metals and chemicals. The Commission said cobalt is commonly used in electric-vehicle batteries, magnets and hard metals, while polycyclic aromatic hydrocarbons are found in steel, iron and aluminium production. (employment-social-affairs.ec.europa.eu) The Commission’s 2025 proposal set a cobalt limit of 0.01 milligrams per cubic meter for inhalable particles and 0.0025 milligrams per cubic meter for finer respirable particles, with six-year transitional limits for industry. It proposed a polycyclic aromatic hydrocarbons limit of 0.00007 milligrams per cubic meter, a general 1,4-dioxane limit of 7.3 milligrams per cubic meter, and a short-term 1,4-dioxane limit of 73 milligrams per cubic meter. (employment-social-affairs.ec.europa.eu) Council governments adopted their negotiating position on December 1, 2025, and added an occupational exposure limit for isoprene beyond the Commission’s original package. Council said the revision should follow the latest scientific evidence and “no one should get sick from going to work.” (consilium.europa.eu) Council documents put the number of workers exposed at about 113,000 for cobalt and inorganic cobalt compounds, 1,284,052 for polycyclic aromatic hydrocarbons, 31,150 for 1,4-dioxane, and 1,200,000 for welding fumes. Those same documents say future occupational exposure to cobalt, polycyclic aromatic hydrocarbons and welding fumes is expected to result in more than 30,000 cancer cases over time without stronger controls. (data.consilium.europa.eu 1) (data.consilium.europa.eu 2) This is the sixth update in a longer European Union effort that the Parliament’s research service traces back to 2016, with repeated revisions to add substances and lower limits as scientific evidence changes. A separate law lowering exposure limits for lead and diisocyanates was adopted in February 2024. (europarl.europa.eu) (consilium.europa.eu) After the April 15 committee vote, Parliament can move into negotiations with Council on the final text. That next round will decide whether the European Union’s industrial push comes with stricter exposure caps for the people doing the work. (europarl.europa.eu)
