The DENIOS Quantity Checker App
Are hazardous substances stored legally? At what quantity does a hazardous materials cabinet become necessary? How much can be stored outdoors?
Companies face these questions when introducing new chemicals or reassessing existing storage situations. Instead of reading through complex regulatory documents, users can simply turn to the DENIOS Quantity Checker.
sitegeist developed a globally unified classification system for chemicals and their labeling on packaging and in safety data sheets. The app is now available on iPhone, iPad, and Android devices.

The DENIOS Compatibility Checker App
Are different hazardous substances being stored together in compliance with regulations? According to TRGS 510, some combinations are allowed, others only with restrictions, and some are strictly prohibited. To help businesses remain compliant, sitegeist developed the Compatibility Checker App as a hybrid application available for iPhone, iPad, Android devices, and PCs.
This powerful tool includes all the relevant regulations from TRGS 510. Users select two or more substances and instantly see whether combined storage is permitted.
Key Features
- Compare an unlimited number of storage classes
- Clear results using a traffic light system: combinations are permitted (green), restricted (yellow) or prohibited (red)
- In the case of restricted combined storage (yellow), you can see exactly what must be observed in order to store the hazardous substances together
- If storage together is not permitted (red), the reason is given and the general requirements that must be met for storing the substance
If you select two or more hazardous substances or storage classes, the app shows which combinations are permitted (green), restricted (yellow) or prohibited (red). Information on relevant laws and regulations is displayed on a separate tab.
