The Generic SUMI Method (GSM) is a comprehensive method for processing Safe Use Mixture Information (SUMI) for mixture safety data sheets (SDS) in line with REACH.
The GSM does provide a single, automatable solution for all in between and end-use formulators to process the relevant SUMIs (if applicable) for the mixture SDS, based on:
1. A ready-to-use SUMI Format. The key characteristics of the GSM SUMI format are:
• One SUMI format presenting safe use advice information for mixtures (physical chemical, worker and environmental risks) in an easy to understand format for users of mixtures (anywhere in the supply chain); The GSM SUMI is a kind of Workplace Safety Card in line with the OSH criteria.
• One SUMI format aligned to any sector with an operational DUCC Template (old style) / Use Map (new style with SWEDs and spERCs);
• More complex justification and scaling information is captured in a separate SUMI SPECIFICATION form.
2. A mixture Chemical Safety Assessment (mixture CSA) process. The key characteristics of the GSM Mixture CSA process are:
• Verifies if the typical use conditions (operational conditions and risk management measures) on a SWED/spERC are safe to use the sector-specific SUMI (if identified) and/or to generate mixture specific SUMIs when the sector-specific SUMI is not safe or not available
• Provides a complete and justifiable mixture CSA process to check / generate the use conditions by the combination of a quantitative risk assessment determining the Risk Characterization Ratio’s (RCR) of the relevant components and a qualitative risk assessment based on the mixture label and the activities.
• The mixture CSA process is covering the physical chemical, worker and/or environmental risks (if applicable).
