OECD HPV Dossiers

In 1998, the Chemical Industry set itself the goal of delivering assessments to the OECD by providing data and initial hazard assessments for approximately 1,000 HPV chemicals, representing more than 90% of global chemicals production.

The information gathered consists of a Screening Information Data Set (SIDS) Dossier, which is a basic set of health and environment data required for making an initial hazard assessment of HPV chemicals by the member countries of the OECD. SIDS data are used to "screen" the chemicals and set priorities for further testing or risk assessment and risk management activities.

The HPV programme is facing several challenges. The demands placed on company resources by REACH - the Europe Union's chemicals legislation - have limited industry's ability to move more rapidly on its HPV commitments. This is true for both EU and non-EU companies with registration obligations and has resulted in fewer HPV submissions.


Euro Chlor is committed to improving the management and knowledge of its chemicals through voluntary initiatives such as the International Council of Chemical Associations (ICCA) HPV (High Production Volume) Initiative and is actively working to support consortia and companies in developing timely and high quality dossiers for chlorinated compounds on the ICCA HPV list.

ECSA actively supports the Swiss authorities in preparing the SIDS Dossier for the Methylene Chloride
substance and Carbon Tetrachloride substance.

Montreal Protocol Meeting - ECSA & HSIA side event

November 2017

DCM & the ozone layer
24 November 2017 – 13hrs – Montréal

During this side event, we will provide you with scientific facts and figures on the worldwide production, emissions of the VSLS Dichloromethane (DCM) and its negligible contribution to ozone depletion.
We will consider the following criteria: global production by industry and emissions, global natural production, behavior and effect on the atmosphere, regulatory overview for DCM. The full paper is available here.

IOELVs for DCM, CTC and PER published

February 2017

Indicative Occupational Exposure Limit Values (IOELVs) for DCM, CTC and PER have been published by the EU Commission (cf. DIRECTIVE (EU) 2017/164 of 31.1.2017), which are in line with the REACH DNEL(inhalation) for workers. 
These IOELVs have to be considered by member states for setting national exposure limits (OELs), which they have to accomplish by 21. August 2018. Only national OELs are legally binding for occupational safety, whereas the IOELVs have to be considered by users in case no OELs is set, yet.  The relevant OELs are provided with the SDS of the solvents suppliers (cf. chapter 8.1). 


IARC monograph on DCM

January 2017

DCM has been re-classified by IARC (IARC website) from Group 2B (Possibly carcinogenic to humans) to the next higher Group 2A (Probably carcinogenic to humans). This reclassification from 2014 has been published recently (Dichloromethane).In the opinion of ECSA the reclassification is not scientifically justified. IARC Monograph classifications are also questioned by other associations such as the American Chemical Council (ACC). However the IARC classification is of no regulatory relevance in EU as European legislation is triggered by classification according to the CLP (GHS) regulation (EC 1272/2008).  


New Study on DCM

October 2016

Together with HSIA, ECSA supported a study to clarify the mode of action of cancer formation for methylene chloride (DCM). A publication is expected soon in a peer reviewed scientific journal. The outcome of the study shows that below a threshold there is no risk on cancer formation related to DCM.
