The past ten years have seen significant changes in the manner in which workplace safety is monitored. The worldwide standard for Safety Data Sheets (SDS) replaces the Material Safety Data Sheet (MSDS). 

This is no minor change, and it was driven by the Globally Harmonized System, a global 16-section system that offers new, clean language and easily interpreted pictograms that transcend languages. Throughout the US, from busy manufacturing plants to quiet research facilities, these new MSDS’s are being added in conjunction with the old ones, and they now provide clarity and consistency of information on a variety of topics, from safety precautions to emergency response, eliminating the confusion of previous proprietary MSDS formats. 

In the final analysis, this significant change has made hazard communication much simpler, providing employees and employers alike with better safety information than ever before. 

From MSDS to SDS: A Decade of Safety Evolution  

The change from Material Safety Data Sheets (MSDS) to Safety Data Sheets (SDS) was a significant change in the communication of chemicals around the world. This was achieved through the Globally Harmonized System (GHS). This change from 2012’s OSHA rules has streamlined the availability of more consistent data sheets for easier access and added new features such as the 2024 HCS. 

 

A Short Look Back in Time 

MSDS had its roots in the 1960s because of maritime industry requirements and was formalized as OSHA’s Hazard Communication Standard (HazCom) in 1983. The format, sequence of sections, and wording of these documents were very dissimilar, which made it harder to locate important safety information quickly. 

With the expansion of international trade, the early 2000s saw inconsistencies in national systems causing confusion and safety issues. The United Nations initiated the GHS program in 2003, aiming to harmonize classification, labeling, and SDS globally. There were changes to the regulations. 

 

OSHA’s 2012 HazCom 

OSHA amended HazCom in 2012 to conform to GHS Revision 3. In order for there to be compliance with the latest version of HazCom, chemical producers, importers, and employers are required to conform fully before June 1, 2015. The three steps would include “Phase 1 – Training Programs” to begin in December 2013, “Phase 2 – SDS/Labels” starting June 2015, and “Phase 3 – Workplace Programs” to begin June 2016. 

This update brought about a harmonized set of hazard criteria for health and physical risks. It prescribed the GHS elements to be included in the label and ensured compliance with the 16-section SDS format. During the implementation, employers may use either system, which made it easier to adapt. 

Key Structural Differences:

SDS adopted a fixed 16-section structure, unlike MSDS’s variable layout.  

Aspect  MSDS  SDS 
Format  Varied sections, inconsistent order  Mandatory 16 sections 
Hazard Info Location  Scattered (e.g., first-aid anywhere)  Fixed: Section 2 (hazards), 4 (first-aid), 8 (PPE/exposure) 
Signal Words/Pictograms  Optional, inconsistent  Required: “Danger”/”Warning” + GHS icons 
Regulatory Details  Often omitted or scattered  Sections 12-15 (ecological, transport, etc.) 
Accessibility  Primarily paper-based  Supports digital or cloud storage 

This uniformity speeds up finding information, which lowers the chance of making mistakes in high-stakes situations. 

Main Parts of SDS: 

  • Identification 
  • Finding hazards (GHS pictograms and phrases) 
  • Information on the chemicals and their makeup 
  • Steps to take in an emergency 
  • Steps to put out a fire 
  • Steps to do if something is accidentally released 
  • Storing and handling 
  • Personal safety and exposure controls 
  • The physical and chemical properties 
  • How stable and reactive it is 
  • Information about toxicology 
  • Information on the environment 
  • Things to think about when throwing things away 
  • Information about transportation 
  • Information on rules and regulations 
  • More information 

 

After 2012 

Most nations made the switch: the EU did it through the CLP Regulation (complete alignment in 2015), Canada did it through WHMIS 2015, and Australia and New Zealand did it by 2017. India’s 1989 laws for the manufacture, storage, and import of hazardous chemicals say that there must be 9 sections. However, 16-section SDS that follow GHS rules are encouraged and utilized a lot. 

By 2015 

Countries that use GHS will require SDS and stop using old MSDS. Tools like CloudSDS make it easier to manage several jurisdictions and support both formats throughout transitions. 

After 2015 (2016–2026) 

GHS changes still had an effect on SDS. The 2024 HCS update from OSHA (which goes into effect on July 19, 2024) is in line with GHS Rev. 7. It changes hazard classifications such as 

Skin corrosion/irritation (adding non-animal tests) 

  • Flammable gases 
  • Aerosols 
  • Desensitized explosives 

The 2024 Update Timeline 

Other enhancements include better readability, more flexible labeling for small packages, and more precise ranges for trade secret concentration. SDS updates must happen within three months of getting new hazard information. 

Latest Updates of 2026 

As of 2026, OSHA’s 2024 HCS rollout continues per this timeline:

Compliance Date  Requirement  Applies To 
May 19, 2026 (22 months)  Update labels or SDSs for substances  Manufacturers, importers, distributors 
Nov 20, 2026 (28 months)  Update workplace labels, HazCom programs, training for substances  Employers 
Nov 19, 2027 (40 months)  Update labels or SDSs for mixtures  Manufacturers, importers, distributors 
May 19, 2028 (46 months)  Final workplace labels, programs, training for mixtures  Employers 

GHS Rev. 11 adds climate/pressure risks and sensitization guidelines, driving future SDS revisions. EHS platforms like CloudSDS now feature AI for predictive modeling, non-animal testing integration, and automated multi-language compliance. Annual audits confirm alignment, reducing citation risks from legacy MSDS. 

 

Advantages for EHS Workers  

Standardization cuts down on the time it takes to train people and the time it takes to respond to events. Research indicates that employing a consistent structure may reduce understanding errors by as much as 25%. Digital SDS solutions automate upgrades, inventory management, and access in many languages, which is very important for businesses that operate throughout the world. In food hygiene or industrial settings, knowing exactly what the risks are in Section 2 helps keep people from being exposed. Audits every year make sure that everyone is following the rules as they change. Adding SDS to LMS makes the application work better for EHS leaders. 

 

Issues and Solutions for Following the Rules 

There were still obsolete MSDSs around after 2015, which could lead to citations. Without automation, version control is still hard. Here are some suggested fixes: 

  • Management in the cloud for changes in real time 
  • Checks to make sure GHS is in line with 
  • Notices about rules (like OSHA and EPA listings) 

 

What to Expect Next 

You may expect GHS Rev. 11+ integrations, AI-powered SDS development, and an emphasis on testing that doesn’t utilize animals. CloudSDS and other EHS technologies will be updated to include predictive hazard modeling. Following the 2024 HCS in full by 2027 will make sure that protections are strong. 

This decade’s move from MSDS to SDS, along with its enhancements, has made safety language more consistent. This has saved lives and money while keeping up with business and research.
