By default, you will always see the OELs (Occupational Exposure Limits) of your country.
OEL Binding Regulatory OELs (BRO)
OEL Indicative Regulatory OELs (IRO)
A substance can have a different OEL value in each country and also a different regulatory status.
For example: an OEL can be Binding in one country and Indicative in Europe. In this case, the color in QUARKS will correspond to the strictest status (binding).
