## Why GHS and Hazard Communication Essentials for Supervisors Matters

Supervisors are often the first point of contact when employees have questions about workplace hazards.

A worker may ask:

* What is this chemical?
* What hazards does it present?
* Where is the SDS?
* What PPE should I use?
* How should this product be stored?
* What should I do if there is a spill?
* What does this pictogram mean?
* Has this chemical been properly labelled?

Supervisors need enough knowledge to recognise these issues and direct employees towards appropriate procedures and information.

**GHS and Hazard Communication Essentials for Supervisors** helps develop that knowledge.

The course introduces the key principles of hazard communication and GHS while focusing on how supervisors can apply these principles within everyday workplace operations.

* Gases under pressure
* Reactive substances

### Health Hazards

These may include:

* Acute toxicity
* Skin irritation
* Serious eye damage
* Sensitisation
* Carcinogenicity
* Reproductive toxicity
* Specific target organ effects

### Environmental Hazards

Some substances may also present environmental risks if they are released into the environment.

Supervisors will learn how hazard classifications can influence workplace controls, employee training, storage arrangements, PPE requirements, emergency planning, and handling procedures.

The module also emphasises that supervisors should not rely on assumptions based on a product’s appearance, familiarity, or previous experience.

A chemical that appears harmless may still present significant hazards.

By completing this module, learners will be better prepared to recognise chemical hazard categories and understand why classification matters for workplace safety.

* Accidental releases
* Handling and storage
* Exposure controls
* Physical and chemical properties
* Stability and reactivity
* Toxicological information
* Disposal
* Transport
* Regulatory information

Supervisors will learn why employees should have appropriate access to relevant SDSs and why SDS information should be considered when planning work involving hazardous chemicals.

The module also examines workplace labelling.

Learners will explore the importance of ensuring that chemical containers are appropriately identified and that employees understand the information provided on labels.

Supervisors will develop greater awareness of potential labelling problems, such as missing information, damaged labels, or unidentified containers.

By completing this module, learners will be better prepared to support effective SDS access and workplace chemical labelling practices.

—

# Module 4: Pictograms and Symbols

Visual communication can provide workers with an immediate indication of potential hazards.
