MSDS, SDS, and GHS: How SDS Regulations Changed Chemical Safety
If you work with hazardous chemicals, you’ve likely seen the terms MSDS, SDS, and GHS used together—often interchangeably. But under today’s SDS regulations, these terms have specific meanings tied to OSHA’s Hazard Communication Standard (HazCom), 29 CFR 1910.1200. Understanding msds sds ghs requirements helps employers stay compliant and ensures workers can quickly find reliable hazard information.
At a high level: MSDS is the older format, SDS is the current standardized format, and GHS is the global system that influenced the standardized SDS structure and labeling rules.
MSDS vs SDS: What’s the Difference?
The difference between MSDS and SDS is primarily about standardization and consistency.
What an MSDS is (legacy format)
An MSDS (Material Safety Data Sheet) was widely used before OSHA aligned HazCom with GHS. MSDS documents often varied by supplier, industry, and country, which made them harder to navigate quickly—especially during emergencies.
What an SDS is (current OSHA-aligned format)
An SDS (Safety Data Sheet) follows a consistent 16-section format designed to make information easier to find. Under OSHA’s HazCom (29 CFR 1910.1200), manufacturers and importers must develop SDSs for hazardous chemicals and employers must maintain and provide access to them.
When people search msds vs sds or safety data sheets vs msds, they’re usually asking:
- Is MSDS still acceptable?
- Do I need to replace MSDS documents with SDSs?
- Does OSHA require the 16-section format?
Important: OSHA’s HazCom requires SDSs for hazardous chemicals and expects the standardized format aligned with GHS (commonly the 16-section SDS). Employers should ensure their library contains current, supplier-provided SDSs.
GHS and SDS: How They Work Together
GHS and SDS are tightly connected. GHS (Globally Harmonized System of Classification and Labeling of Chemicals) is an international framework that standardizes how chemical hazards are classified and communicated.
What GHS changed
When OSHA updated HazCom to align with GHS, it strengthened hazard communication by requiring:
- More consistent hazard classifications
- Standard label elements (signal word, hazard statements, pictograms, precautionary statements)
- A standardized SDS structure
This is why the term msds sds ghs shows up so often: GHS is the “why” behind the shift from MSDS to SDS.
The 16 sections of an SDS (quick overview)
While OSHA’s HazCom requires SDSs, the globally recognized GHS format is the familiar 16-section structure:
- Identification
- Hazard(s) identification
- Composition/information on ingredients
- First-aid measures
- Fire-fighting measures
- Accidental release measures
- Handling and storage
- Exposure controls/personal protection
- Physical and chemical properties
- Stability and reactivity
- Toxicological information
- Ecological information
- Disposal considerations
- Transport information
- Regulatory information
- Other information
Even if you’re not writing SDSs yourself, knowing this layout helps you audit documents for completeness and train workers to locate critical information quickly.
SDS Regulations Under OSHA: What Employers Must Do
Under OSHA 29 CFR 1910.1200, employers using hazardous chemicals have specific duties related to SDS regulations. These requirements apply broadly across general industry, and similar hazard communication expectations exist in other settings.
Core SDS-related compliance requirements
In practical terms, employers must:
- Maintain an SDS for each hazardous chemical in the workplace
- Ensure SDSs are readily accessible to employees in their work areas during each work shift
- Provide employee training on hazardous chemicals, including how to read labels and SDSs
- Maintain a written Hazard Communication Program describing how the site meets HazCom requirements
Common compliance gaps include missing SDSs for newly purchased products, outdated documents lingering in binders, and access issues when teams work across multiple locations.
“Readily accessible” in the real world
OSHA expects workers to be able to obtain SDS information without barriers—especially during emergencies. For many organizations, that means moving from paper binders to a centralized digital approach, provided employees can still access the SDSs when and where needed.
Safety Data Sheets vs MSDS: Why the Change Improves Safety
The shift from safety data sheets vs MSDS isn’t just a terminology update—it’s a usability improvement.
Benefits of SDS standardization
- Faster emergency response: First aid and firefighting information appears in consistent sections.
- Improved training outcomes: Workers can learn a repeatable “map” for every product.
- More reliable hazard communication: GHS-aligned classification supports consistent hazard statements and pictograms.
Where MSDS documents still show up
You may still find MSDS files in older archives, long-lived operations, or legacy supplier documentation. However, relying on an MSDS when an SDS is available can create confusion and increase compliance risk—especially if the hazards, ingredients, or recommended controls have changed.
Managing SDS Regulations at Scale: Common Challenges
Even organizations with strong safety programs struggle with day-to-day SDS management, particularly when they have many products, multiple sites, or frequent purchasing changes.
Typical SDS management problems
- SDSs stored in multiple places (binders, shared drives, email threads)
- No clear ownership for requesting updated SDSs from suppliers
- Inconsistent naming conventions and duplicate files
- Lack of visibility into what chemicals are onsite and where they’re used
These challenges directly affect your ability to meet HazCom expectations for availability, accuracy, and employee access.
How SwiftSDS Helps With SDS Regulations, GHS, and Compliance
A modern SDS program needs more than storage—it needs organization, accessibility, and traceability. SwiftSDS is a comprehensive Safety Data Sheet management platform that helps businesses handle the practical realities of msds sds ghs compliance.
With SwiftSDS, organizations can:
- Build a centralized SDS library in a secure cloud-based system
- Improve OSHA HazCom (29 CFR 1910.1200) readiness by keeping documents organized and accessible
- Support GHS and SDS alignment with consistent SDS organization and faster retrieval
- Track chemicals with inventory management (locations, quantities, expiration dates)
- Enable mobile access so workers can pull SDS information from any device—helpful for multi-site operations and field teams
For teams transitioning from legacy binders to digital access, SwiftSDS also helps reduce the risk of missing documents and makes it easier to standardize how SDSs are stored and found.

Practical Steps to Strengthen Your SDS Program
If you’re reviewing your program for msds vs sds alignment and HazCom readiness, these steps can help.
- Inventory your chemicals by site and work area.
- Verify you have an SDS for every hazardous product.
- Replace outdated MSDS files with current supplier SDSs.
- Confirm SDSs are readily accessible for all shifts and work areas.
- Train employees to locate key SDS sections (first aid, PPE, spill response).
- Implement a centralized system like SwiftSDS to keep everything current and searchable.
Tip: Treat SDS management as a living process—new products, reformulations, and supplier changes can quickly make libraries incomplete.
Call to Action: Make SDS Compliance Easier With SwiftSDS
SDS regulations under OSHA’s Hazard Communication Standard are clear—but managing msds sds ghs documentation across real workplaces can be complex. SwiftSDS helps you centralize your SDS library, support GHS-aligned hazard communication, and give workers fast mobile access when it matters.
