The Evolution of CoSHH Hazard Symbols
The Transition from Orange to Red and Black Symbols
The journey of CoSHH Hazard Symbols is a fascinating one, marked by significant changes over the years. One of the most notable transitions was the shift from orange to red and black symbols.
In the early days of hazard communication, orange symbols were used to denote various hazards. These symbols, known as the “orange square symbols,” were simple and straightforward, but they lacked the striking visual impact needed for immediate recognition of potential dangers.
Recognizing the need for more effective hazard communication, a decision was made to transition to red and black symbols. The new symbols, framed within a red diamond, were designed to be more visually striking and immediately recognizable. The use of black pictograms against a white background within the red frame ensured high contrast and visibility, even from a distance.
This transition was not just about aesthetics; it was a strategic move designed to enhance safety. The red and black symbols are more alarming to the human eye, prompting individuals to take notice and exercise caution when handling hazardous substances.
The Role of CHIP and CLP Regulations in this Evolution
The transition from orange to red and black symbols was guided by two key sets of regulations: the Chemicals (Hazard Information and Packaging for Supply) Regulations 2009 (CHIP) and the Classification, Labelling and Packaging Regulations 2008 (CLP).
CHIP was the first regulation to introduce the orange square symbols in the UK. It required suppliers to provide hazard information about chemicals and to package them safely for supply.
However, in 2009, the European Union adopted the Globally Harmonized System of Classification and Labelling of Chemicals (GHS), leading to the introduction of the CLP regulations. The CLP regulations mandated the use of the new red and black symbols, aligning the UK with global standards for hazard communication.
The transition period from CHIP to CLP lasted from 2009 to 2017, during which time suppliers could use either the orange or red and black symbols. However, from June 1, 2017, the use of the new red and black symbols became mandatory.
The evolution of CoSHH Hazard Symbols, guided by these regulations, reflects an ongoing commitment to improving safety standards. By ensuring clear, consistent, and effective hazard communication, these symbols play a crucial role in protecting individuals from the risks associated with hazardous substances.
