You can request updated safety data sheet versions directly via a group email to your suppliers and read them in via the standardised SDScomXML interface. The REACH-conform archiving of your hazardous substance documents is ensured.
Obligation to update
When there are changes to a hazardous substance, GeSi³ automatically notifies you of updating requirements for the hazardous substance risk assessment or hazardous substance operating instructions. Changed limit values are also displayed.For more information...
Your advantage
You can immediately identify the need for action from the dashboard in the hazardous substance management software and can save your individual to-do-lists as a repository.
Document distribution
With GeSi³, you can easily distribute your hazardous substances index across different locations via the internet. This also applies to operating instructions and safety data sheets, which are linked to the hazardous substances index.For more information...
Your advantage
You do not incur any additional costs for the distribution of the documents. The documents are always up-to-date thanks to the hazardous substance management software.
Manage hazardous substance conveniently and easily
“The GeSi³ hazardous substance management software links hazardous substances with their places of use, storage locations, risk assessments and operating instructions. As a result, evaluations and registers can always be retrieved and printed/exported in their latest version. The data can also be stored interactively on your own intranet for easier access.”

Your path to REACH-conform hazardous substance management with our software

Overview of features
GeSi³ has integrated the “Easy-to-use workplace control scheme” from the Federal Institute for Occupational Safety and Health You can easily determine the inhalative, dermal and physico-chemical hazards including risk visualisation and proposed measures based on the hazardous substance exposure and a few hazardous substance data.
Hazardous substance operating instructions are created by GeSi³ from the hazardous substance data, also in conjunction with your customised operating instructions template if required. Group operating instructions can also be automatically generated using the wizard.
An operating instruction for a hazardous substance and different workplaces remains one operating instruction! This simplifies data maintenance and is very easy to implement through the automatic entry of the workplace data in the header of the operating instruction and automatic creation of individual PDF documents, which include different location-specific data if required.
Joint storage prohibitions in accordance with TRGS 510 can be visualised based on the storage class, either specifically in relation to a storage section or individually for selected hazardous substances. It is also possible to determine storage classes.
Based on your individual operational structure and the maximum quantities stored, GeSi³ calculates if the operating range belongs to the lower or upper class, thereby offering an interface to plant safety.
In GeSi³, emails can be sent automatically for various tasks, e.g. bulk email to request new safety data sheet versions. There are numerous configuration options. The email function uses the general GeSi³ address book. When using the email task, all emails are previewed before sending and can still be changed.
GeSi³ determines the current occupational exposure limit values and biological limit values on the basis of the ingredients of a hazardous substance and displays them in the context of the hazardous substance risk assessment. Ingredient can be conveniently identified using the CAS or EC No.!
GeSi³ contains the current status of the REACH candidate list including the substances subject to authorisation and provides queries such as: Which hazardous substances have ingredients included on the current REACH candidate list? This makes it a starting point for substitution.
When creating operating instructions, all legally prescribed pictograms are available for customised placement, either on the outside left or right, or centred in relation to sections. You can also integrate your own pictograms.
For a consistent appearance of your operating instructions, you can use a template which reflects your desired layout (frame colour, QM footer, logo) and contains company-specific standard wording in certain fields. You can also integrate your own pictograms.
The status of a hazardous substance or a hazardous substance operating instruction can be visualised by means of a version assignment. Each version is stored in the version archive and can be traced at any time.
Many evaluations and queries are available, relating to hazardous substance management and with reference to your own operational structure, which make it easy for you to have a good overview at all times. In addition, you can also create individual to-do lists (so-called repositories).
For cross-site hazardous substance management, module-related permissions can be assigned, users and groups can be created and differentiated document protection can be specified: Operating instructions from one site can only be viewed and copied by users at another other site, but cannot be changed.
GeSi³ is well suited for use by service providers in the area of hazardous substance management. They can provide your customers with a web-based, linked hazardous substances index or transfer data to them for further processing (if the customer also works with GeSi³).
