  • 2 GB as the first target size
    • a significant factor are annexes to hazardous substances or premixtures
    • as well as annexes (mostly photos) to risk assessments
    • another important factor is versioning
  • 10 GB should therefore be available if a lot of annexes are used
  • The size of the database is not influenced by whether a single-user or network database is used.

About us – GeSi-Software GmbH from Würzburg

From the research project “Hazardous substances and safety” to the established GeSi software for safety data sheets, hazardous substances and occupational health and safety

We produce the GeSi³ software solution – software for safety data sheets, hazardous substances and occupational health and safety. It all started with the research project “GeSi” more than 25 years ago. GeSi stands for “Gefahrstoffe und Sicherheit”, which is German for hazardous substances and safety. Our target back then was the same as it is now: to make it safer to handle hazardous substances in companies and to provide practical tools for businesses in the trade. We are an interdisciplinary team (particularly chemists, occupational physicians and IT specialists) who, right from the start, have been developing the software very close to the user and their practical requirements. Due to the close personal contact with users during training courses, specialist conferences and support, our objective is to create software which is simple and intuitive. By now, GeSi³ is used successfully by over 500 companies in the D-A-CH region.
