3.2.1. Safety Data Sheets — Reading and Applying Them
💡 First Principle: A Safety Data Sheet (SDS) is a standardized document that tells you everything you need to know about a chemical's hazards, safe handling, and emergency response — all in one place. OSHA requires one SDS per chemical product used in the workplace, and it must be accessible to any employee at any time during their shift.
SDS sheets replaced MSDS (Material Safety Data Sheets) when OSHA updated its Hazard Communication Standard. The new format has 16 standardized sections, making it easier to find specific information quickly.
The 16 SDS sections — exam-relevant highlights:
| Section | Content |
|---|---|
| 1 | Product identification, manufacturer contact |
| 2 | Hazard identification — what dangers does this chemical pose? |
| 3 | Composition/ingredients |
| 4 | First-aid measures — what to do if exposed |
| 5 | Fire-fighting measures |
| 6 | Accidental release/spill measures |
| 7 | Handling and storage requirements |
| 8 | Exposure controls/PPE — what protection is needed during use |
| 9 | Physical and chemical properties |
| 14 | Transport information |
| 15 | Regulatory information |
| 16 | Other information, including revision date |
OSHA Hazard Communication Standard (HazCom) requirements:
- An SDS must exist for every hazardous chemical in the workplace
- SDS sheets must be readily accessible to employees during all work shifts
- Employees must be trained to read and use SDS information
- SDS sheets must be kept current (verify the revision date)
💡 Key Point: "Readily accessible" means available immediately without having to call someone, look up a password, or wait. A binder in the supply closet accessible to all employees during their shift is compliant. A file on the manager's locked computer is not.
⚠️ Exam Trap: The exam may describe a scenario where SDS sheets are stored somewhere but not easily accessible (locked office, off-site, on the owner's phone). This is an OSHA violation regardless of whether all the SDS sheets exist. Existence is not sufficient — accessibility is required.
Reflection Question: Your salon uses 12 different chemical products. Where should the SDS sheets be kept, and when must they be accessible?
