TRGS 510 regulates the safe storage of hazardous substances in portable containers in Germany. Annex 3 contains the co-storage compatibility matrix indicating which storage classes may be stored together.
There are 19 storage classes (LGK), from explosive substances (LGK 1) to non-combustible solids (LGK 13). Our interactive calculator checks compatibility per TRGS 510 Annex 3.
In practice, incorrect co-storage is one of the most common mistakes in hazardous substance storage. This tool instantly checks the compatibility of two storage classes.
