A Safety Data Sheet (SDS) is the standard document that describes a chemical, its hazards and how to handle it. Reading it before you order helps you confirm the product is right for your use and that you can store and handle it safely.
Where to start
An SDS is organized into 16 numbered sections in a standard order. You do not need to read every line first, but these sections matter most when you are choosing a product.
The sections to check first
- Section 1, identification: confirms the product name, supplier details and recommended use.
- Section 2, hazard identification: shows the hazard classification, signal word and hazard statements.
- Section 3, composition: lists ingredients and CAS numbers. Match the CAS number to the chemical you intend to buy.
- Section 7, handling and storage: lists storage conditions and materials to keep it away from.
- Section 8, exposure controls and PPE: describes protective equipment and ventilation.
- Section 9, physical and chemical properties: appearance, pH, flash point and similar data, which help you compare grades.
- Section 10, stability and reactivity: shows what to avoid mixing or exposing it to.
- Section 14, transport information: shows how the product is classified for shipping.
Check the details that change from product to product
Two products with the same name can have different concentrations, grades or forms, and the SDS is specific to the product it covers. Check the concentration in Section 3, the revision date, and the supplier named in Section 1. If something does not match what you expected, ask before you order.
SDS, specification sheet and label are different documents
The SDS covers safety and handling. A specification or technical data sheet describes product quality, such as assay or purity. The container label gives a short hazard summary. You will often want both the SDS and the specification.
Keep SDSs current
SDSs are updated from time to time. Keep the current version with the product where employees can reach it, and ask your supplier for a new copy when you reorder if you are unsure of the revision.
SDS content is general information. For the safety, regulatory or legal requirements that apply to your operation, rely on the SDS itself and your own safety and compliance staff.
A short worked example
Suppose you are comparing two suppliers of the same acid. Both quotes list the same product name, but the SDS for each tells you more. In section 3 you may see different concentrations. In section 9 the physical properties, such as appearance and pH, may differ. In section 7 the storage advice may call for different materials for containers or for keeping the product away from certain other chemicals. These differences can change which grade you actually need, how you store it, and what training your staff require. Reading the two SDSs side by side before you order is much easier than discovering a mismatch when a drum arrives. If something is unclear, such as an unfamiliar abbreviation or a transport classification, ask the supplier to explain it. NTC can pass on the SDS and specification for the products we supply, and we are glad to answer questions about them. Your own safety and compliance staff remain responsible for how the product is handled at your site.
