Four new legal OELs in the Netherlands on October 1, 2014

As of October 1, 2014, four Dutch legal limits as TWA 8 hours have been set for the substances Acetic acid, Calcium dihydroxide, Cresol and Picric acid.

  • Acetic acid (CAS# 64-19-7): Legal 25 mg/m3. SCOEL and ACGIH recommend to use also a STEL of 50 mg/m3 in controlling exposure.
  • Calcium dihydroxide (CAS# 1305-62-0): Legal 5 mg/m3. Health-based recommendations (SCOEL, DFG) are 1 mg/m3/8 hour and 2 to 4 mg/m3/15 minutes.
  • Cresol, all isomers (CAS# 1319-77-3): Legal 22 mg/m3 with Skin-notation. SCOEL and the Dutch Health Council don’t give a health-based recommendation. In Sweden OELs of 4,5 mg/m3/8 hour and 9 mg/m3/15 minutes are used. The recent REACH dossier has a DNEL of 0,9 mg/m3 to prevent local irritation.
  • Picric acid (CAS# 88-89-1): Legal 0,1 mg/m3. SCOEL and the Dutch Health Council don’t give a health-based recommendation. The substance is a skin sensitizer and has a weak genotoxic potential.

 

Although these new OELs ​​are useful for enforcement, we recommend that you take a more thorough approach to protect the health of workers and controlling exposure. The above information is derived from DOHSBase Compare, which uses​​ the hierarchy of OELs as presented at September 25, 2014 during the NVvA/ NVT-AT meeting on the future of OELV policies (http://www.tsac.nl/publicaties/Presentation_H3-statement_based_kick-off_levels_140925.pdf, sheet 10).
