Title: Safety Data Sheets (SDS) Explained
Type: Lesson
A Safety Data Sheet (SDS) is a detailed document that provides information on how to safely handle, use, store, and dispose of a chemical. It also outlines what to do in case of a spill, exposure, or fire.
Employers must have an SDS for every hazardous chemical in the workplace — and they must be readily accessible to all employees.
MSDS was the older version (Material Safety Data Sheet)
SDS is the updated format under GHS and OSHA’s 1910.1200
SDS follows a standard 16-section format worldwide
Here’s a breakdown of the most important sections:
| Section | Content |
|---|---|
| 1 | Identification – name, use, manufacturer |
| 2 | Hazards – pictograms, signal word, classification |
| 3 | Composition – ingredients and concentrations |
| 4 | First-Aid Measures – what to do if exposed |
| 5 | Fire-Fighting Measures – how to fight chemical fires |
| 6 | Accidental Release – spill cleanup steps |
| 7 | Handling & Storage – safe practices and conditions |
| 8 | Exposure Controls – PPE, ventilation, limits |
| 9 | Physical/Chemical Properties – appearance, odor, flashpoint |
| 10 | Stability & Reactivity – what causes dangerous reactions |
| 11 | Toxicology – health effects and exposure symptoms |
(Sections 12–16 include ecological, disposal, transport, regulatory, and other info)
SDS must be:
Available during every shift
Stored in print or digital format (no locked cabinets!)
Updated if a chemical formulation changes
If you can’t find an SDS — ask your supervisor immediately and do not use the chemical.
The SDS is your go-to resource for understanding how a chemical behaves — and how to protect yourself from harm. You should always review it before using an unfamiliar chemical.
