SUMI is the acronym for “Safe Use Mixture Information”.

The term SUMI was introduced by the Exchange Network on Exposure Scenarios (ENES) discussing how to process safe use information in the mixture SDS in compliance with the REACH Regulation (EC) 1907/2006. SUMI is the suggested output of the REACH obligations for the formulators to process the relevant exposure scenarios of the substance components of the mixture and to be annexed to the mixture SDS.

Various sectors, under guidance of the Downstream Users of Chemicals Coordination group (DUCC), have developed sector-specific SUMIs based on a sector specific Use Map with sector-specific SWEDs (Sector-specific Worker Exposure Descriptions). The SUMI aims to present safe use advice information for mixtures (workers exposure) in an easy to read format for the end-users of mixtures.
More details on the SWED/SUMI approach can be checked at the DUCC website and in our REACH Position paper.

The SUMI is also the key output of the Generic SUMI Method (GSM).
A SUMI that is created based on this method is presenting safe use advice information for mixtures (physical chemical, worker and environmental risks) in an understandable and informative way for users of the mixture. It can be used as ready-to-use work place safety card to meet the OSH needs of users of mixtures. The GSM SUMI is a single format aligned to sector specific Use Maps or that can be used for mixtures without such sector specific Use Map.
