The benefits of the GHS labeling system are quite clear. They make it easy to identify potential hazards related to chemicals at just a glance, which is one of the reasons why it is so popular today.

The big question I have about GHS labels is when are they required? Is it really necessary to apply these labels on individual containers of a specific chemical, for example? Do trucks transporting chemicals from one building to another one the same company campus have to have the labels in place? Where can I find answers to these types of questions?
