Safety Data Sheet (SDS): 16 Sections Explained
Learn the 16 sections of a Safety Data Sheet with simple explanations and practical information for workplace chemical safety.
📘 What is a Safety Data Sheet (SDS)?
A Safety Data Sheet (SDS) is an important document that provides information about a chemical product, including its hazards, safe handling requirements, storage conditions, emergency measures and environmental considerations.
SDS documents help workers, supervisors, HSE professionals and emergency responders understand chemical hazards and the precautions necessary to work safely.
Understanding the 16 SDS sections makes it easier to quickly find important information when handling, storing, transporting or responding to a chemical emergency.
⚠️ Important Safety Point
Always read the relevant SDS before using a hazardous chemical.
Make sure workers understand the hazards, required PPE, safe handling procedures, storage requirements and emergency precautions.
