Which section changed during the SDS conversion?

The section that changed during the Safety Data Sheet (SDS) conversion is one that specifically addresses updates made to the document over time. The section titled "Section(s) changed since last revision" is crucial because it provides users with information regarding what updates or amendments have been made to the SDS since the last time it was reviewed. This transparency is important for ensuring that users are aware of any significant changes that could impact safety and compliance.

Having this information readily available allows users to stay informed about any modifications in the data, be it in hazard communication, protective measures, or handling instructions. Such knowledge is vital for ensuring workplace safety and regulatory compliance, as it keeps all stakeholders updated on any adjustments that could affect how the chemical should be handled or the risks associated with it.
