The Role of Safety Data Sheets (SDS) in Hazard Communication

The Role of Safety Data Sheets (SDS) in Hazard Communication

Clear and readily accessible Safety Data Sheets (SDS) are essential for preventing potential hazards in the workplace. Picture a warehouse where employees regularly handle industrial solvents. By consulting the SDS before use, workers gain critical knowledge on proper storage, usage, and disposal, ensuring they can manage these substances safely and effectively.

But what would happen if there were no SDS? Workers wouldn't know about potential hazards or how to mitigate risk when working with hazardous chemicals. Understanding safety data sheets remains key to workplace safety, particularly regarding hazard communication practices. This blog explains what safety data sheets are and how they help keep workplaces safe.

What are Safety Data Sheets (SDS)?

A Safety Data Sheet (SDS), formerly known as Material Safety Data Sheet (MSDS), stands as a standardised document containing essential information about hazardous chemicals. Safety data sheets (SDSs) are hazard communication materials that communicate the hazards, precautions, and safe handling instructions for each chemical in a workplace. They standardize how hazard information is communicated, serving as a crucial resource so everyone remains safe and informed. SDSs contain useful information, functioning much like a rulebook for handling potentially dangerous items responsibly.

When is a Safety Data Sheet (SDS) Used?

SDSs are indispensable in workplaces dealing with hazardous chemicals, and their use spans multiple scenarios. Here's when they are utilised:

• New Hazardous Chemical: An SDS offers essential info on handling, storing, and hazards of new chemicals at work.
• Safety Audits: Supervisors use an SDS to ensure hazardous substances comply with safety rules and regulations.
• Employee Training: An SDS helps employees learn about chemical risk and safe handling measures during training.
• Emergency Response: An SDS guides responders on safe actions during chemical spills or exposure.

Why Safety Data Sheets Matter

Hazard Communication

Firstly, SDSs serve as the primary form of hazard communication, especially in workplaces dealing with chemicals like acids, solvents, pesticides, and similar substances. SDSs help communicate information on each chemical's properties, including health effects, physical hazards, and environmental risk. Having a standardised way to communicate hazards helps keep everyone on the same page. An SDS ensures that workers consistently access critical data, regardless of a chemical's manufacturer or origin. For guidance on flagging concerns beyond chemical exposure, see our article on how to report a hazard in the workplace.

Compliance with WHS Regulations

In Australia, workplaces using hazardous chemicals must follow duties under the Work Health and Safety (WHS) Regulations. Primary responsibility falls on the person conducting a business or undertaking (PCBU). PCBUs must identify and classify hazardous chemicals using the Globally Harmonized System (GHS). They must also maintain accurate labels and safety data sheets for each chemical, supporting broader compliance with WHS obligations across the business.

Understanding the Structure of an SDS

So, what makes up an SDS? SDSs follow a standard 16-section format, with each section containing specific information about physical and chemical properties of a substance. Sections include:

• Identification: Includes chemical name, supplier info, and uses.
• Hazard(s) Identification: Lists handling hazards, GHS classification, and precautions. This section contains hazard classification details specific to the substance.
• Composition/Ingredients: Details ingredients, concentrations, and hazardous impurities.
• First-Aid Measures: Immediate actions for accidents.
• Fire-Fighting Measures: Fire-fighting guidance and equipment.
• Accidental Release Section: Handling spills safely.
• Handling and Storage: Safe practices and storage advice.
• Exposure Controls/Protection: Exposure limits, PPE, and hazard controls.
• Physical/Chemical Properties: Physical attributes like appearance and melting point.
• Stability and Reactivity Section: Stability and reactivity hazards.
• Toxicological Information: Health effects, symptoms, and toxicity.
• Ecological Information: Environmental impact and disposal guidance.
• Disposal Considerations Section: Safe waste disposal methods.
• Transport Information: Handling and labelling for transport.
• Regulatory Information: Applicable regulatory requirements.
• Other Information: Preparation and revision dates.

How to Interpret SDS Information

Knowing sections of an SDS is one thing, but understanding the information within is another. Below is a guide on reading and interpreting SDSs:

Hazard Information

Hazard Symbols

In an SDS, a chemical's hazards are often represented using symbols or pictograms, which are graphical representations indicating the hazard associated with a chemical. Each symbol corresponds to specific hazards defined by the GHS. For example:

• Flame: Indicates flammability
• Skull and Crossbones: Represents acute toxicity or fatal hazards
• Exclamation Mark: Signifies less severe hazards such as irritants or skin sensitisers.

Precautionary Statements

Precautionary statements give instructions for safe handling and use of a hazardous chemical. These statements follow standardised formats, divided into three categories:

• Prevention: Measures to avoid exposure (e.g., "Wear protective gloves")
• Response: Actions to take in case of an incident (e.g., "If swallowed, do not induce vomiting")
• Storage: Recommendations for safe storage conditions (e.g., "Store in a cool, dry place")

Classifications

The hazard classification section outlines specific risks associated with the chemical, including:

• Signal Words: "Danger" indicates a more severe hazard than "Warning."
• Hazard Statements: These explain the hazards (e.g., "Causes skin irritation") and are coded (e.g., H315 for skin irritation) to show severity quickly.

First-Aid Measures and Emergency Response

Interpreting First-Aid Instructions

The first-aid measures section provides critical information on how to respond to exposure incidents based on the route of exposure:

• Inhalation: Move the affected person to fresh air and seek medical attention if symptoms persist.
• Skin Contact: Remove contaminated clothing and rinse skin with water for at least 15 minutes.
• Eye Contact: Rinse eyes cautiously with water for several minutes; remove contact lenses if present.

Handling Spills and Leaks

The SDS includes specific instructions for managing spills or leaks:

• Containment: Use absorbent materials to contain spills.
• Cleanup Procedures: Follow safe methods for cleaning up hazards, often needing PPE like gloves and masks.
• Disposal Information: Includes guidance on proper waste disposal of contaminated materials.

Best Practices for Using an SDS

Access to a Safety Data Sheet only proves beneficial if workers know how to use and interpret them correctly. Some best practices for implementing SDSs include the following approaches.

Integrate an SDS into Workplace Safety Protocols

Integrating SDSs into workplace safety protocols means making Safety Data Sheets a fundamental part of your organisation's safety management practices. For instance, employees should have access to SDSs before handling any hazardous chemicals. How can you do it? This involves several key actions:

• Maintaining an SDS Register - A register is a comprehensive list of all hazardous chemicals used, stored, or produced in the workplace, forming part of broader chemical management practices. It should include links to relevant SDSs.
• Training on Reading and Understanding SDS - Educate employees on how to use and interpret SDSs, using available resources and reference tools where needed.
• Regular Reviews - Ensure you regularly review and update the SDS register as new chemicals come into use or SDSs get revised.

Comply with Australian WHS Regulations

Another best practice for utilising SDSs involves compliance with WHS regulations. As mentioned above, SDSs fall under governance of these regulations, which align with the GHS of Classification and Labelling of Chemicals. Here are key requirements regarding SDSs in Australia:

• Manufacturers and importers of hazardous chemicals must prepare an SDS before supplying them to workplaces.
• The SDS must be in English and include information relevant to Australian conditions.
• The SDS must include 16 sections covering various chemical aspects.
• Review the SDS every five years or when new information on the chemical becomes available.
• All SDSs must follow GHS 7 rules, which feature updated hazard classes and safety instructions starting January 1, 2023.
• Suppliers can face legal issues if they don't provide a compliant SDS, including liability for injuries caused by poor hazard communication.

Use Correct Personal Protective Equipment (PPE)

An SDS includes specific safety precautions for safely handling or using every hazardous chemical. These instructions may include using personal protective equipment (PPE), such as gloves, goggles, and respirators. For example, if a chemical proves highly toxic when inhaled, the SDS recommends wearing a respirator, alongside broader risk management measures suited to that particular task.

Incorporate an SDS in Emergency Planning

Incorporating SDS information into emergency response plans proves critical. This involves understanding chemical hazards present at your workplace and having an evacuation plan ready in case of an incident. Additionally, emergency response plans should include instructions on accessing SDSs and communicating hazards to first responders if needed. Workplaces managing vehicles alongside chemicals may also benefit from reviewing our guide on managing vehicle safety in the workplace.

Complement Your SDS with Safety Documents

Safety Data Sheets should not be the only source of information on hazardous chemicals in your workplace. Employers may also provide other safety documents, such as Safe Work Method Statements (SWMS), risk assessments, and Standard Operating Procedures (SOPs), to complement SDS information within a broader safety management framework. Businesses coordinating multiple contractors might also find value in understanding the chain of responsibility in transport safety.
