New workplace safety regulations signed to protect workers from hazardous chemicals

New regulations aimed at strengthening protections for workers exposed to hazardous chemicals have been signed into law by Minister of State Alan Dillon.

The updated rules, introduced under the Safety, Health and Welfare at Work (Chemical Agents) (Amendment) Regulations 2026 and the Carcinogens, Mutagens and Reprotoxic Substances (Amendment) Regulations 2026, implement EU Directive 2024/869 into Irish law.

The measures are designed to reduce the risks associated with exposure to substances such as lead and diisocyanates, which can have serious long-term health effects, including impacts on fertility, the nervous system and respiratory health.

Minister Dillon said the regulations demonstrate the Government’s commitment to workplace safety.

“This Directive adds a further layer of protection for workers,” he said, noting that industries have already taken steps to improve training and awareness around chemical exposure.

For the first time, EU-wide exposure limits have been introduced for diisocyanates, chemicals commonly linked to asthma and skin conditions. Across the EU, an estimated 4.2 million workers are exposed to these substances.

The new rules also strengthen protections around lead exposure, requiring ongoing medical monitoring for workers with elevated blood-lead levels, even if exposure occurred in the past. Stricter limits have also been set for female workers of childbearing age.

Minister for Enterprise Peter Burke said the regulations would deliver tangible health benefits.

“The benefits include reduced illness, improved quality of life for workers and better outcomes for families,” he said.

The Health and Safety Authority has been credited for its role in supporting workplace compliance and promoting training, particularly in sectors where chemical exposure risks are highest.

The updated regulations, alongside revised codes of practice, ensure that Ireland is fully aligned with EU standards on worker protection.

The move is expected to impact a wide range of industries, including construction, manufacturing and pharmaceuticals, where chemical exposure is more common.
