Summary


The Health and Safety Commission would like your comments on proposals for occupational exposure limits (OELs) for chemical substances. A form is included at the back of this booklet to help you do this. It repeats the questions set out at appropriate points in the text below.

  • three new Maximum Exposure Limits (MELs) for substances formerly assigned Occupational Exposure Standards (OESs): chloroethane, hydroquinone and manganese and its inorganic compounds (1) ;
  • withdrawal of five OESs for: glycidyl ethers (2,3-epoxypropyl ethers);
  • withdrawal of an OES for subtilisins (proteolytic enzymes as 100% pure crystalline enzyme);
  • withdrawal of an OES for sulphuric acid;
  • no change to OES for para-phenylenediamine, but introduction of a skin notation for this substance; and
  • narrowing of the criteria for applying one OES: mineral oil mists in order to exclude metal working fluids (for which separate HSE guidance is planned).
