Hazard Communication – Transition to the Globally Harmonized System (GHS)

Hazard Communication

The Problem

Imagine driving in a foreign country where road signs are completely unfamiliar. It’s confusing and potentially dangerous. For years, that’s how chemical labeling and hazard communication felt in workplaces—different formats, inconsistent information, and a lack of clarity. Workers had to hunt for critical safety details, and recognizing hazards quickly was often impossible. Today, we’ll discuss the solution: the Globally Harmonized System (GHS), a universal safety language for chemicals. We’ll explore how it simplifies hazard communication, improves workplace safety, and what your role is during this transition.

Identify the Hazards

Under the old system, workers faced these challenges:

  • Inconsistent labeling formats made hazard identification difficult.
  • Material Safety Data Sheets (MSDS) varied in structure and content, making it hard to find critical safety information.
  • Lack of standardized symbols created language barriers for global workers.

These inconsistencies led to mistakes, slower emergency responses, and a higher risk of chemical-related injuries.

Safety Practices and Preventative Measures

The new GHS system resolves these issues by standardizing hazard communication worldwide. Here’s how you can adapt:

1. Understand Safety Data Sheets (SDS):

  • SDS replaces MSDS, with a consistent 16-section format.
  • Critical information—like hazard identification and emergency procedures—is always in the same place, making it easy to locate.
  • Familiarize yourself with this layout for quicker access to safety details.

2. Recognize New Labels:

  • Labels now include:

    some text
    • Signal Words: “Danger” or “Warning” to highlight severity.

    • Hazard Statements: Standardized phrases describing risks.

    • Pictograms: Visual symbols enclosed in red diamonds for quick hazard recognition.

    • Precautionary Statements: Steps to ensure safety.

  • Think of these labels like nutrition facts—consistent and clear.

3. Learn the Pictograms:

  • Eight pictograms indicate hazards like flammability, toxicity, and corrosion.
  • These symbols transcend language barriers, helping workers identify dangers instantly.

4. Adapt During the Transition:

  • Both old and new formats may coexist during the transition.
  • Focus on learning the new system but don’t discard your knowledge of the old one yet.

5. Be Proactive:

  • Ask questions if any labels or SDS sections are unclear.
  • Help coworkers adjust to the new system by sharing what you learn.

Real-Life Case or Scenario

Where possible, use an actual incident that you have experienced or been involved in.

E.g. Consider this scenario: A worker handled a chemical container without realizing it was corrosive because the label used unfamiliar terminology. They suffered severe skin burns that could have been avoided if the label had included GHS pictograms. The new system ensures hazards are communicated clearly and universally to prevent incidents like this.

Employee Responsibilities

  • Learn the new GHS format for labels and SDS.
  • Pay attention to pictograms, signal words, and hazard statements.
  • Report any confusion about labels or SDS to your supervisor.
  • Support coworkers in understanding and adapting to the new system.

Employer Responsibilities

  • Provide training on the GHS system, including SDS and labels.
  • Ensure all chemicals are properly labeled according to GHS standards.
  • Replace outdated MSDS and labels with GHS-compliant formats.
  • Offer resources for employees to learn the new system.

Discussion & Questions

  • "What differences have you noticed between the old and new labeling systems?"
  • "Which pictograms or label elements are most helpful for recognizing hazards?"
  • "What challenges have you faced while adjusting to the GHS system?"
  • "How can we support each other in learning this universal safety language?"

Commitment/Action Plan

Starting today, commit to reviewing SDS and labels thoroughly before handling any chemical. Take time to familiarize yourself with the new pictograms and encourage others to do the same. Let’s work together to make this transition smooth and prioritize safety.

Wrap-Up

While change can be challenging, the GHS is an upgrade from a fragmented system to a universal safety language. This system ensures that hazards are easier to recognize and that everyone can work safely with chemicals. Thank you for your attention, and let’s embrace these changes as an opportunity to enhance workplace safety.

Standards Overview

  • The Hazard Communication Standard (HCS) aligns with GHS to ensure global consistency in chemical labeling and hazard communication.
  • OSHA mandates all manufacturers and employers to adopt GHS formats, including standardized Safety Data Sheets (SDS) and pictogram-labeled containers.
  • Employers are required to train workers on these updates to prevent confusion and ensure safety during the transition.
