At the Lead Registrant workshop held last week in Helsinki, ECHA, the European Chemicals Agency, stressed once again the importance of a good chemical safety report (CSR) as key to ensure better protection of human health and of the environment.
A good CSR ensures information passed down to downstream users are of value to ensure safe use of the substances, and that the risks are adequately controlled evidenced by appropriate and meaningful risk assessments.
The whole process of carrying out a chemical safety assessment (CSA), as key part of the CSR is new for many companies, understanding the expectations of what a CSR should contain is still ongoing but lessons are being learnt.
But first of all what is a CSR?
Chemical Safety Reports (CSR) combine and consolidate the information contained in the IUCLID5 end points. The purpose is to make a risk assessment comparing the hazard assessment collected from the data studies versus the exposure assessments of chemical substances for workers, consumers and the environment.
A manufacturer or importer of a substance in quantities of 10 tonnes or more per year needs to prepare a chemical safety assessment (CSA) and needs to document this assessment in their chemical safety report (CSR) as part of the joint registration dossier. For hazardous substances there is an additional obligation to perform an exposure assessment.
The Chemical Safety Report submitted to ECHA as part of the registration dossier must document the results of the CSA, Exposure assessment and Risk Management (if required).
Important aspects of the CSR are to build exposures scenarios based on accurately defined and appropriate use descriptors, calculate the exposure estimates with the risk assessment tools and finally calculate the risk characterisation ratio comparing the hazard assessment against the exposure assessment. Exposure scenarios have to be documented in the Chemical Safety Report (CSR) and communicated to the downstream users as annexes to the Safety Data Sheets.
To prepare the ES, suppliers need to liase closely with their customers to ensure that the scenario for exposure is realistic, feasible and conversely, once prepared, the user must not deviate from the operational conditions and risk management measured outlined in the ES. When one considers the aspect of enforcement, it is important to realize that the CSR and the eSDS will serve as documentary evidence to support what practically has been undertaken within the workplace.
ReachCentrum, in collaboration with TNO Triskelion is offering a series of training courses combining CHESAR, the tool from ECHA helping companies to carry out their CSA and to prepare their CSR, the Advanced Reach Tool (ART), and Stoffenmanager, both are web-based occupational risk assessment and risk control tools for companies. Further information on these trainings, to be held on 13, 14 and 15 February is available here.
On 27 and 28 March 2012, ReachCentrum and Peter Fisk Associates are organising two one-day workshops to help you understand how to focus on the vital information that is being conveyed through your e-SDS. Further information on the workshop “e-SDS and Exposure Scenarios – Their Interpretation and Use” is available here.
