Getting started with SharedSDS

Obtain a login by getting in touch. See the About us page. We will issue a temporary password and you can login, change your password and start entering data. We will also include you in the users mailing list for community or help-desk support with any questions.


Visit the server 

Production server - https://ssds.sharedsds.com/admin/

Staging server - https://staging.sharedsds.com/admin/ [1]

This screenshot shows all the areas covered for a user with admin, editor and author permissions. Manager permissions would also show the workplace section.


Click Substances or mixtures  ... +Add - to arrive at the new substance page. But first, while you can still see the main menu above ... (try Ctrl + once or twice to enlarge images and Ctrl - to restore things)

Theory of operation

Note that you do not start with a new SDS. In the screenshot above there is no +Add button against SDSs. This is because everything begins with the substance and the SDS is created automatically on the first save and updated automatically on every subsequent save of the substance or mixture. Manual changes to the SDS are protected from automatic regeneration or updating when the substance is saved.

For a new substance, click +Add and start entering the intrinsic properties on the Substance screen. This should be a gradual process as you check the SDS (click the [View on site] button) taking shape every time you [Save].

To finalise the SDS, GHS hazards, precautions need to be confirmed on the SDS screen reached via the main menu above.

Mixtures are substances with other substances added as ingredients. This is the crux of SharedSDS. Purple book calculations based on ingredient properties deliver mixture classifications. The ingredients can be your own or those licensed from another SharedSDS user company. Reaction products can be defined with their own ingredients and properties. Mixtures can be mixed and all ingredients automatically aggregated in the parent mixture for hazard classification.

This is the Substance screen you see when you click +Add

The page title is "None" because you have not yet named the substance. It is shown here in full to give you an idea of the expandable section headings. Also note below that there are sections for Solid, Liquid, Gas and Aerosol - because you have not yet specified which it is.  Physical form will be one of the first things you save.

Add new substance

General procedure is to enter data and save as you go. Nothing gets changed/saved until you click one of the [Save] buttons. At that point, the business rules for data entry are checked and certain violations may be detected to prevent bad data being saved.

Although there are sections here for you to write as much as you need, best SharedSDS practice is to decide after all the automatic hazards and precautions have been included exactly how much additional description is necessary. 


To enter data click a (Show) link to reveal fields and help-text in that labelled section. Like this ...

 GHS classification occurs when you click [Save]. However, if you change substance properties you should blank out the pertinent classification so it can be recalculated. Always remember, you can (with very few exceptions) override a SharedSDS calculated classification by putting in your own.


Ongoing procedure is to update substance data and check the SDS (View on site) until it has advanced as far as possible using substance data alone. Finally you can leave this substance screen and open the SDS screen to finish off your work and make the SDS effective.


[1] Note that the staging server gets blown away and rebuilt from time to time. It is also used to regularly test production server relocation to prove we can keep going at a different location in the event of disaster. On request we can load a particular production backup on the staging server and roll back the software to that date to show you your data from the past.
