UK Health and Safety Laboratory announces one-day COMAH course
Published:  23 September, 2016

COMAH: The application of CLP and Aggregation in the COMAH 2015 Regulations, 19 October, Buxton, UK.

The course is aimed at safety managers and those responsible for compliance with the COMAH Regulations at upper tier and lower tier sites, as well as at sites that were previously outside of scope of the COMAH 1999 Regulations but may have potential to come into scope of the new regulations.

The Control of Major Accident Hazards Regulations (COMAH) 2015 came into force 1 June 2015. One of the major changes introduced by the regulations is the use of the Classification, Labelling and Packaging (CLP) Regulations to classify the hazardous properties of chemicals and to use these classifications to decide if establishments are in scope. The new classification scheme brings with it the potential for sites to change their COMAH status (upper tier, lower tier or non-COMAH) depending on the substances and quantities held.

The course will give an overview of the requirements of the new Regulations. It will also cover the potential changes in scope brought about by the CLP classifications, how to determine the CLP classification of chemicals and how to apply the COMAH aggregation rules to determine the COMAH status of a site. The presenters have been providing scientific advice to the UK team which negotiated the SEVESO III Directive implemented in the UK by the COMAH 2015 Regulations.

The course will cover:

  • Introduction to the COMAH 2015 Regulations highlighting the major changes to the scope introduced by the application of CLP
  • Alignment of COMAH 2015 with CLP
  • How to determine CLP category for acute toxicity - pure substances and mixtures
  • How to determine GHS category for environmental hazards (M factor method)
  • The application of the aggregation rules
  • A classification and aggregation exercise

The course will be run at the HSL laboratory in the spa town of Buxton.

The cost of the course is £495 per person (includes course notes, lunch and refreshments). To book a place visit:
