The Commission is empowered to adopt delegated acts in accordance with Article 9a to make strictly technical amendments to the Annexes, in order to take account of technical harmonisation and standardisation of the design, manufacture or construction of parts of workplaces, technical progress, changes in international regulations or specifications and knowledge with regard to workplaces.

Where, in duly justified and exceptional cases involving imminent, direct and serious risks to workers’ and other persons’ physical health and safety, imperative grounds of urgency require action in a very short timeframe, the procedure provided for in Article 9b shall apply to delegated acts adopted pursuant to this Article.
