12 Introduction to (short) Generic Exposure Scenarios (GES) For assessment of exposures at local scale, several generic exposure scenarios (GES) were developed in the chemical safety report (CSR) for each zinc substance. This was necessary because of the significant number of uses that was identified for each of the substances. The multitude of identified uses was assigned to the respective GES based on similarity of process, and, consequently, similarity in exposure and risk management measures. So, GES are relevant for the different identified uses that they group at the same time. Approaches for local exposure assessment Assessment of workers exposure is related to the place /process the worker is involved in. The GES group different processes; exposure assessment is done using the worst case approach by considering full shift exposure at the workplace with highest potential for exposure. Risk management measures are specified accordingly. Environmental emissions (notably to water) are usually integrating the totality of emissions from a given site, and cannot be distinguished for each process. Therefore assessments in the GES are done for the site as a whole. Shortened GES for annexing to the e-sds For reasons of clarity, shortened versions of the GES as documented in the CSR have been listed below. These shortened versions focus on a) operational conditions and b) risk management measures. Repetition of information contained in the SDS has been avoided by cross-referencing. How to identify the GES related to a given use? In table below, the generic exposure scenarios (GES) developed for Zn metal are presented. Table: Generic exposure scenarios (GES) for zinc metal (ref : CSR zinc metal, version Nov 2010) Number Sector Uses Code 1 Formulation step: melting, alloying and Formulation general GES Zn 1 casting in massive pieces 2 Formulation step: melting, alloying GES Zn 2 manufacture of powders 3 First tier applications Manufacturing of other GES Zn 3 zinc compounds 4 Laboratory reagent GES Zn 4 5 Use of molten zinc GES Zn 5 6 Transformation of GES Zn 6 massive zinc 7 Use of zinc powders GES Zn 7 8 Second tier applications DU of massive pieces of GES Zn 8 zinc 9 DU of preparations containing zinc powder GES Zn 9 To facilitate the identification of the GES related to a given downstream use, the table below lists the different uses that were identified for Zn metal. In this table, the downstream user can look up its use(s) and find the corresponding GES for attachment to his e-sds. Page 3 sur 24
