Chlorine makes human life safer. Its most universally recognised application is in water treatment for human consumption, considered by many to be one of the greatest discoveries of the last millennium, without which the history of humanity would have been substantially different. But its importance goes far beyond this extraordinarily important or even decisive application.
As an infiltrating agent, chlorine is present, but not visible, in thousands of products that are part of our day-to-day lives. Through integration into essential chemical compounds in the most diverse production processes, its scope is remarkable, as is the impact of its dozens of derivatives.
The so-called "chlorine tree", graphically illustrating the branches (derivatives) and fruits (products) obtained from this chemical element, highlights its importance in a crucial area of society – safety in its broadest sense.
