It is a legal requirement that applicable occupational exposure limits (OELs) be given in GHS SDS section 8. Considering that different countries may have developed different occupational exposure limits for the same chemical substances, you cannot simply put 1 value in your global SDS. In this article, we will show you how to quickly find international occupational exposure limits and list them in the section 8 of GHS SDS.
There are usually 3 types of occupational exposure limits. Not all of them are available for a hazardous chemical agent.
The common units of OELs include ppm and mg/m3.
The easiest way to find international occuptional exposure limits is to use GESTIS. It is a free database containing a collection of occupational limit values for hazardous substances gathered from various EU member states, Australia, Canada, Japan, New Zealand, Singapore, South Korea, Switzerland, China, and the United States. Limit values of almost 1,800 substances are listed.
For example, if you search Acetonitrile or CAS No. 75-05-8 in GESTIS, all OELs in different countries will pop up.
For substances, occupational exposure limit values must be give if applicable (depending on availability and destination market). For mixtures, all applicable exposure limit values for individual harmful substances must be listed. In EU, available Derived No-effect Levels (DNELs) must also be listed if there is no applicable union exposure limit or national exposure limit value.
If you supply your product to just one country, you only need to list the applicable occupational exposure limit value for that country. If you wish to supply your product to multiple countries and use one SDS, you may list different the limit values as what Gestis database has shown you above.
