End 2015 up to beginning 2016, Jongerius Consult and Caesar Consult have further tested and optimized the generic SUMI approach with in an orientating pilot of five DSM products with various mixture uses (connected to the uses, typical operating conditions (OC) and typical risk management measures (RMM) from the standardized uses tables of CEPE and UPR).
The SUMI approach further evolved in a complete mixture chemical safety assessment, verifying / upgrading the typical OC/RMM for the sector specific mixture uses on the SUMI(s). It combines the results of a risk based, qualitative look-up table to select personal protective equipment for skin, hands, eye and inhalation based on the mixture hazards and exposure potential as well as from a quantitative assessment based on the mixture composition.
The SUMI format and SUMI approach can be used for making SUMIs and SUMI SPECs for any mixture – mixture use combination.
The overall conclusion of the orientating DSM pilot is that the SUMI approach results in risk based SUMI’s that are well designed, that are based on a mixture chemical safety assessment and that are clear for the end-user. The split output of a SUMI with only the relevant safe use information for the users (to be attached to the mixture SDS) and a separate SUMI-SPEC was appreciated although according to DSM needs further assessment by Downstream Users. The SUMI SPEC with additional more specific technical information will be provided on request for further downstream scaling or justification. Also the focused presentation of only a few recognizable environmental safe use information fields on the SUMI and the relatively simple process (aligned to the Cefic/VCI LCID methodology) are appreciated.
Parties did discuss the opportunities and challenges to further implement and benefit from the generic SUMI approach as formulator as well as for the upstream registrants. Stakeholder acceptance of the generic SUMI approach and automation in connection with the SDS system(s), e.g. as a “SUMI checker”, was seen as the two main points of attention.
