During the Triennial Congress of the International Commission on Occupational Health held in Marrakesh, Morocco, 28th-April to 3rd May the ICOH renewed its collaboration agreement with the IEA and the International Occupational Hygiene Association. The MOU was signed by the Presidents, Prof. Seong-Kyu Kang for ICOH, Dr Samantha Connell for IOHA and Prof. José Orlando Gomes for the IEA. This is the third such agreement and its renewal reinforces the willingness of these three internationally important professional associations representing occupational physicians, hygienists and HFE specialists, who are active in workplace health and safety protection. We look forward to continuing the work together, particularly the plans to hold a joint Congress on informal work in Colombia in 2026.
