Chemicals must be stored safely and securely. If not stored properly, they may pose a danger to people and the environment. This applies especially to hazardous substances.

The properties of individual substances and products and the quantities stored are not the only factors in the hazard potential posed in the storage of chemicals. Storing different chemicals together may lead to an enhanced risk that shouldn’t be underestimated. When damage occurs, e.g. caused by leakage or a spill, the chemicals may mix and cause a violent reaction.The result may be the formation of dangerous gases or vapors, but ignition is also possible.
VCI, the German Chemical Industry Association (VCI, has developed guidelines for the joint storage of chemicals (“Leitfaden zur Zusammenlagerung von Chemikalien”) so that not every individual product has to undergo evaluation. This concept has been integrated in TRGS 510 "Storage of Hazardous Substances in Nonstationary Containers” (TRGS = Technical Rules for Hazardous Substances,, according to which each product is classified as belonging to a storage class by virtue of its specific hazard properties. Hazardous products with hazards that are considered to be of the same kind and hence require the same safety precautions are grouped into one storage class. Each product is classified as belonging to one storage class only. In so doing, hazardous properties have been primarily taken into account that require special preventative action in terms of fire and explosion protection. Examples of these properties are “posing an explosion hazard”, “highly flammable”, “extremely flammable”, “combustible” or “oxidizing”. In products posing more than one hazard, classification is done according to the ranking of hazard properties.
In the Joint Storage Table of TRGS 510 there are defined properties for every storage class indicating whether joint storage with any of the other storage classes is allowed in principle, whether joint storage is prohibited (separate storage required), or whether joint storage is subject to a restriction (e.g. separate storage required where storage takes place in the same section of a warehouse).
When complying with TRGS 510 and the regulations referring to it an employer can be assured that the requirements imposed by the Hazardous Substances Ordinance (GefStoffV) are satisfied in the storage of chemicals.
