Occupational cancer is the leading cause of work-related death in the EU, yet it receives a fraction of the boardroom attention directed at acute hazards. The December 2025 publication of EU-OSHA’s Workers’ Exposure Survey on occupational cancer risk factors changes that. Ireland is one of only six countries surveyed, giving Irish employers the most granular carcinogen exposure data the country has produced. The findings are an actionable roadmap for prevention.

The survey’s headline figure — 46.6 million EU workers probably exposed to at least one cancer risk factor in their most recent working week — reflects decades of under-prioritised prevention rather than new danger. For the first time, employers have a sector-by-sector baseline across six member states including Ireland. UV radiation and diesel emissions are the most frequent exposures, cutting across outdoor work, transport, agriculture and construction. Employers who treat this as a starting point for structured assessment will find the path to risk reduction clear and achievable.

The survey covers 24 known cancer risk factors across 98.5 million European workers, assessed by sector, job type and demographic group. Chemical laboratories consistently report strong technical controls, and the gap between their practice and that of other sectors is where the greatest prevention opportunity lies. EU-OSHA’s OccIDEAS exposure assessment tool, which underpins the survey, is available to support workplace-level evaluation and gives Irish employers a structured methodology immediately applicable to their operations.

The findings are informing revisions to the EU Carcinogens, Mutagens and Reprotoxic Substances Directive, which sets legally binding occupational exposure limits across all member states. In January 2026, updated EU asbestos guidelines advanced progress toward an asbestos-free Europe. In February 2026, EU-OSHA endorsed the fifth edition of the European Code Against Cancer, providing 14 evidence-based workplace prevention recommendations. Ireland’s HSA published a new Code of Practice for Chemical Agents Regulations in 2026, directly relevant to carcinogen management.

For Irish employers, the convergence of WES data, forthcoming legislative revisions and a new domestic Code of Practice creates a structured window for proactive action. Ireland’s participation in WES means national data will directly inform HSA inspection priorities. Organisations that establish carcinogen exposure registers and document substitution decisions now will be well placed as regulatory expectations rise.

Three practical measures provide a starting point. First, conduct a carcinogen exposure inventory using HSA chemical agents guidance and the EU-OSHA WES framework, prioritising UV radiation, diesel emissions and dust given their survey prevalence. Second, apply the hierarchy of controls — elimination and substitution before engineering controls, before personal protective equipment. Third, document and carefully review the assessment annually, embedding carcinogen management as a standing item within the safety management system.

The EU-OSHA Workers’ Exposure Survey gives Ireland evidence-based carcinogen data that employers can act on now and that regulators will use to shape policy ahead. The 100,000 work-related cancer deaths recorded annually in the EU are overwhelmingly preventable. Irish organisations that engage with the findings and embed carcinogen management in their safety infrastructure are already making the most consequential long-term investment in workforce health.
