## Why GHS Essentials for Supervisors Matters

Hazardous chemicals can present many different risks. Depending on the substance and the conditions in which it is used, workers may face hazards such as fire, explosion, toxicity, corrosivity, irritation, sensitisation, or other harmful effects.

Supervisors are often responsible for making sure employees understand workplace procedures and have access to appropriate safety information.

They may also be the first person an employee approaches with questions such as:

* What does this chemical label mean?
* What hazards does this product present?
* Where can I find the Safety Data Sheet?
* What PPE is required?
* How should this material be stored?
* What should I do if there is a spill?
* Does this chemical require special handling?
* What precautions should I take before using it?

Understanding GHS can help supervisors provide better guidance and recognise when additional information, training, or specialist assistance may be required.

**GHS Essentials for Supervisors** provides the foundational knowledge needed to support these responsibilities.
