Hazard Communication – Transition to the Globally Harmonized System (GHS)
The Problem
Imagine driving in a foreign country where all the road signs are unfamiliar. It’s confusing and potentially dangerous. For years, that’s how chemical labelling and hazard communication felt in workplaces — different formats, inconsistent information, and a lack of clarity. Workers had to search for critical safety details, and quickly recognising hazards 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 previous system, workers faced the following issues:
- Inconsistent labelling formats made it difficult to identify hazards.
- Material Safety Data Sheets (MSDS) varied in layout and detail, making it hard to find critical safety information.
- Lack of standardized symbols created language barriers in multicultural workplaces.
Safety Practices and Preventative Measures
Understand Safety Data Sheets (SDS):
- SDS have replaced MSDS and now follow a consistent 16-section format.
- Critical details — such as hazard identification and emergency procedures — are always found in the same place.
- Familiarize yourself with the layout for quick access to safety information.
Recognize New Labels:
- GHS-compliant labels now include:
- Signal Words: "Danger" or "Warning" to indicate severity.
- Hazard Statements: Standard phrases describing specific risks.
- Pictograms: Visual red diamond symbols indicating the type of hazard.
- Precautionary Statements: Instructions for safe handling, storage, and disposal.
- Think of these labels like nutritional labels — clear, concise, and consistent.
Learn the Pictograms:
- There are eight GHS pictograms representing hazards such as flammability, toxicity, and corrosion.
- These visuals help workers identify dangers quickly, regardless of language or literacy barriers.
Adapt During the Transition:
- You may still encounter both old and new formats during the transition period.
- Learn the new system while maintaining awareness of the old one.
Be Proactive:
- Ask your supervisor if you’re unsure about a label or SDS section.
- Share knowledge and help your team adjust to the GHS.
Real-Life Case or Scenario
A worker handled a chemical without realizing it was corrosive because the old label used unfamiliar wording. The worker suffered severe burns. If the label had included a GHS pictogram for skin corrosion, the risk would have been immediately recognized. The new system makes these hazards clear and accessible.
Employee Responsibilities
- Learn the new GHS format for labels and SDS.
- Pay close attention to pictograms, signal words, and hazard statements.
- Report any unclear or missing labels to your supervisor.
- Support your coworkers in learning the system.
Employer Responsibilities
- Provide training on the GHS system, SDS, and labelling changes.
- Ensure all hazardous products are labelled in line with GHS standards.
- Replace outdated MSDS and labels.
- Ensure workers have access to SDS and understand how to use them.
Discussion & Questions
- What differences have you noticed between old and new labels?
- Which pictograms or label elements help you most when identifying hazards?
- What challenges have you faced while adjusting to GHS?
- How can we support each other in learning this universal safety system?
Commitment/Action Plan
Starting today, commit to reviewing labels and SDS before handling any substance. Familiarize yourself with the new pictograms and encourage others to do the same. Let’s support one another and prioritize a safe transition to the GHS system.
Wrap-Up
While change can be challenging, the GHS replaces confusion with clarity. It’s a universal safety language designed to protect all workers. By learning the system and applying it in your daily tasks, you help make the workplace safer for everyone. Thank you for your commitment to safety.
Standards Overview
In Canada, the Globally Harmonized System (GHS) has been adopted through the Workplace Hazardous Materials Information System (WHMIS) under the Hazardous Products Act. Employers must:
- Use GHS-compliant labelling and Safety Data Sheets (SDS) for all hazardous products.
- Train workers on how to interpret GHS labels and SDS.
- Maintain an up-to-date hazardous products inventory and ensure SDS are available for all products
