Evidence Mounts to Rethink Beryllium’s Classification

A recent published study of beryllium workers supports rethinking classifications of beryllium metal under the EU Classification, Labelling and Packaging Regulation (CLP), the GB Mandatory Classification and Labelling List (GBMCL), and the Globally Harmonized System of Classification and Labelling of Chemicals (GHS).
Updated evidence shows that the existing classifications do not accurately reflect scientific realities and risk information related to beryllium-containing materials in the workplace, and should therefore be reconsidered.
The study, “An updated mortality study of beryllium workers, 1925–2020”, followed 17,149 workers across 15 US facilities over nearly a century, making it the largest epidemiologic study on beryllium.
Its central aim was to reassess mortality risks, especially lung cancer, while explicitly accounting for whether workers were exposed to soluble,
insoluble, or mixed forms of beryllium.
By splitting facilities according to beryllium solubility, results show that insoluble-only settings show no increased lung cancer or other mortality for any timeframe for workers.
The study therefore adds momentum to align classification with scientific evidence and modern industrial contexts, while still maintaining strong protections against sensitisation and chronic beryllium disease.
BeST stands ready to provide expertise through its Be Responsible program, helping employers and regulators deliver the highest standards of worker protection.
