The document discusses the upcoming revision of Annex II of REACH, which will standardize Safety Data Sheet (SDS) formats. Key points include: - Annex II will be revised to include 63 obligatory subheadings to clarify and standardize SDS content and format. - The revision is based on the GHS format from the UN's Purple Book and aims to improve hazard communication. - Suppliers will need to update SDS for compliance with the new formats by various deadlines between 2010-2015, which will be a significant workload. - The revision may raise questions from companies regarding how to manage providing standardized SDS going forward, given the increased information requirements.
