Globally Harmonised System (GHS) Signs

GHS Signs are universal symbols used to communicate about dangerous substances and hazards. They're part of the Globally Harmonized System of Classification and Labelling of Chemicals. These signs help people understand the potential dangers of chemicals and how to handle them safely.

In Australia, GHS Signs follow certain standards:

1. Colours: GHS Signs have specific colours. Here's what they mean:

   • Red: Used for fire and flammability hazards.
   • Yellow: Indicates physical hazards like explosions or reactivity.
   • Blue: For health hazards such as toxicity or harm to your body.
   • White: Used for additional information like special precautions.
      

2. Shapes: GHS Signs also use different shapes:

   • Diamond: It's a warning symbol used for physical and health hazards.
   • Square/Rectangle: Typically used for information like safe handling instructions.

These signs are used on chemical containers, workplaces, and transport to ensure everyone knows the risks and how to stay safe when dealing with chemicals.
