## Why Hazard Communication and Chemical Labelling Essentials Matters

Hazardous chemicals can present physical, health, and environmental risks. Workers may encounter chemicals that are flammable, corrosive, toxic, reactive, oxidising, irritating, sensitising, or otherwise hazardous.

Without appropriate information, employees may not know:

* What chemical they are handling
* What hazards it presents
* How exposure could occur
* What precautions are necessary
* What PPE may be appropriate
* How the chemical should be stored
* What to do following a spill or exposure
* Where to find additional safety information

Chemical labels provide an important first source of information. They can communicate a chemical’s identity, hazards, warning information, and recommended precautions.

The **Hazard Communication and Chemical Labelling Essentials** course helps learners understand this information and recognise how it fits into a wider workplace hazard communication programme.
