Organizations that handle hazardous chemicals must ensure effective hazard communication to protect the safety of their workers and product users. Effective hazard communication involves providing a clear overview of the associated risks, along with detailed instructions on how to manage those risks and follow safety guidelines. To streamline and standardize this process, the Globally Harmonized System of Classification and Labeling of Chemicals (GHS) was developed. 

For years, the Occupational Safety and Health Administration (OSHA) has worked to establish effective guidelines to protect organizations and their employees from workplace hazards. The need for a consistent international standard became evident after identifying various challenges. This led to the creation of the Globally Harmonized System (GHS), which has now been widely adopted across the globe. 

The development of GHS and its labels was a natural evolution in chemical safety standards. Your organization might already be using these labels, or you may have encountered them due to compliance requirements. Keep reading as we explain the history of GHS, its definition, and other important details. This will help your organization better understand the importance of GHS. 

 

GHS: In Brief 

 

The Globally Harmonized System of Classification and Labeling of Chemicals (GHS) is a set of international guidelines for classifying and labeling chemicals. It was created to ensure that people worldwide understand the hazards of chemicals they may use or use or meet. These set of rules are managed by the United Nations (UN).  

 

This system comes was designed with the following purposes: 

 

  • Sorting all chemical, health, and environmental dangers.  
  • Ensuring the information given follows global standards. 
  • Keeping this system consistent across all UN member countries. 

 

History of GHS: Significant Turning Points:

 

The 16-section safety data sheets (SDS) and labels we use today are the result of the establishment of GHS. To fully understand how these standards came to be, it’s essential to explore the key milestones and phases in the development of GHS. Check out the points below to discover the evolution and significant steps in the creation of GHS. 

 

1) Its Origin 

The idea for a globally harmonized system (GHS) emerged from the need to standardize chemical hazard communication. OSHA initially addressed hazard communication in the U.S. with the Hazard Communication Standard (HCS) in 1983. The federal agency mainly focused on the manufacturing sector. This early effort recommended an internationally harmonized system. The purpose was to enhance hazard recognition and reduce trade barriers. 

 

2) Expansion and Development 

Between 1987 and 1989, OSHA expanded the Hazard Communication Standard (HCS) to include all industries with potential chemical exposure due to increasing global safety concerns. In 1990, OSHA asked for information about international safety standards and the International Labor Organization’s (ILO) work, paving the way for a more standardized approach. 

 

3) Global Mandate 

In 1992, the Earth Summit, officially known as the United Nations Conference on Environment and Development (UNCED), called for a global system. The purpose was to standardize chemical classification and labeling. This led to the formation of the Inter-Organization Programmed for the Sound Management of Chemicals, which worked to develop a unified system. 

 

4) Formation of GHS 

By 1999, the UN renamed its committee to the Committee of Experts on the Transport of Dangerous Goods and on the Globally Harmonized System of Classification and Labeling of Chemicals (UNCETDG/GHS). This new committee focused on maintaining and promoting the GHS framework. The GHS was formally adopted in 2002. The Economic and Social Council of the United Nations endorsed it by 2023.  

 

5) Implementation and Evolution 

In the early 2000s, there was major progress in adopting GHS. The U.S. started updating its Hazard Communication Standard to match GHS, with OSHA issuing proposals and final rules until 2012. GHS also saw updates to include new hazard classes and maintain global consistency. 

 

6) Recent Updates 

Recent revisions to the GHS, including the 7th and 8th revisions, have further refined the system. Aligning with this revision OSHA will finalize the updates by 2024. The new updates will include revisions, new hazard classification and mention all compliance requirements.   

 

7) Ongoing Developments 

 GHS is still evolving. Countries such as Canada and Australia are updating their regulations to match the latest GHS revisions. The EU and other regions are also adding new hazard classes and updating their safety standards to keep global consistency and protection. 

 

When Was GHS Introduced Officially?

Officially in 2003, GHS was finally introduced. UN published the first edition of the GHS Purple book. Its implementation started with the pesticide labels in 2004. It was adopted by OSHA in 2005, and the agency modified the Hazard Communication Standard (HCS). In February, the Office of Management and Budget (OMB) approved the final rule on GHS, ensuring that the HazCom standard was brought in line with GHS Revision 3.

 

What are the Impacts of GHS? 

 

The introduction of GHS brought numerous advantages. Here are some key benefits that highlight its significance. 

 

  • Improved Safety and Health:  

 

The introduction of GHS enhanced the protection of human health and the environment. It has provided consistent and clear information on chemical hazards. This allows workers and consumers to make informed decisions and take appropriate safety measures. 

 

  • Standardized Communication:  

 

GHS standardizes the classification and labeling of chemicals. This ensures that the same information is conveyed to all countries that have adopted the system. This reduces confusion and errors, particularly in global supply chains. 

 

  • Increased Compliance:  

 

GHS simplifies compliance for companies operating globally by aligning chemical regulations across countries. This reduces the complexity and challenges of meeting various regulatory requirements in different regions. 

 

  • Facilitated Trade:  

 

GHS enhances global trade by standardizing hazard communication. It has become safer and more efficient. This alignment reduces trade barriers and allows products to cross borders more easily. 

 

 

  • Enhanced Environmental Protection:  

 

GHS supports environmental sustainability by ensuring accurate classification and labeling of chemicals. This helps prevent contamination. Moreover, it has become a perfect way to encourage safer practices in chemical use and disposal. 

 

What are GHS Labels? 

 

 Along with Safety data sheets, GHS labels are another key term in the GHS vocabulary. The labels are standardized labels used to show chemical hazards. They include symbols, signal words like “Warning” or “Danger,” and hazard statements. These elements help users understand the risks of a chemical product. The aim is to make sure that anyone, no matter where they are, can easily grasp the dangers of a chemical and take proper precautions. 

In some cases, precautionary statements can also be included along with other vital details. Above all, it is the provider of hazard information that an organization needs to ensure ultimate safety of workers and stay compliant.  

 

 

Importance of GHS Labels: 

 

  • Universal Understanding:  

 

With these labels, people around the world can easily recognize and understand the hazards of chemicals. 

 

  • Enhanced Safety:  

 

The labels have improved safety by making it easier to identify risks quickly. This helps organizations prevent accidents and injuries in the workplace. 

 

  • Regulatory Compliance:  

 

GHS labels ensure that companies meet international safety regulations, reducing the risk of fines or legal issues. 

 

  • Facilitates Trade:  

 

Consistent labeling across countries simplifies the process of selling and transporting chemicals globally. In easy terms, it has helped remove trade barriers. 

 

  • Environmental Protection:  

 

GHS labels provide information on how to handle chemicals safely, reducing the risk of environmental contamination. 

 

 

Conclusion: 

 

The introduction and implementation of GHS labels have indeed marked a revolutionary shift in hazard communication. By standardizing how hazards are communicated, GHS labels have simplified and unified the process across the globe. Examining the history of GHS reveals its core mission: to streamline and improve the way we convey chemical risks. The ongoing revisions of GHS regulations ensure that this system remains up-to-date and effective, continuing to enhance chemical safety and consistency worldwide.
