A hazardous materials storage area is a defined storage zone for substances that impose special requirements on safety, equipment, and organization under hazardous substances law. It encompasses regulations on storage classes, segregation, containment sumps, ventilation, fire protection, and documentation.
Key facts
- A hazardous materials storage area is subject to the Hazardous Substances Ordinance and technical standards such as TRGS 510, which define storage classes, segregation requirements, and mandatory equipment.
- Classifying all stored substances into storage classes is a fundamental prerequisite for compliant planning of containment sumps, ventilation, and fire protection.
- Above certain quantity thresholds, additional permit obligations under emission control law or major accident regulations may apply.
- Warehouse management systems must incorporate blocking logic that prevents the unlawful co-storage of incompatible substances.
- Outsourcing to external hazardous materials storage facilities reduces the internal workload but does not fully release the operator from their responsibilities.
What is a hazardous materials storage area?
A hazardous materials storage area is a defined storage zone in which substances and mixtures classified as hazardous under hazardous substances law are kept – such as flammable liquids, corrosive chemicals, toxic substances, or environmentally hazardous materials. In Germany, the primary legal foundations are the Hazardous Substances Ordinance (GefStoffV) and technical standards such as TRGS 510 (storage of hazardous substances in portable containers). Depending on the substance and quantity, additional regulations from water protection, fire safety, and occupational health law may also apply.
The purpose of a hazardous materials storage area is to reduce risks to employees, assets, and the environment to an acceptable minimum. Requirements vary considerably depending on the type, quantity, and combination of substances stored.
How does a hazardous materials storage area work in practice?
Planning begins with the classification of all substances to be stored into storage classes (LGK 1–13 according to TRGS 510). This determines which substances may be stored together and which must be kept strictly separate – co-storage prohibitions apply, for example, between oxidizing and flammable substances. The following aspects are typically relevant for structural and technical equipment:
- Containment sumps or containment rooms to retain leaks
- Adequate ventilation, explosion-protected where required
- Fire protection measures such as extinguishing agents, fire compartments, or automatic suppression systems
- Labeling of storage areas and containers in accordance with the CLP Regulation
- Access restrictions and blocking logic in the warehouse management system
From an organizational standpoint, operating instructions, employee training, a hazardous substances register, and emergency plans are mandatory. Many companies underestimate the documentation effort: who stores what, when, in what quantity, and in what container condition must be traceable – including for external auditing authorities.
What matters when selecting and designing a hazardous materials storage area?
The most important preliminary question is: which storage classes and quantities are actually present or planned? Both the structural design and the permit requirement depend on this. Above certain quantity thresholds, permits under emission control law or obligations under the Major Accidents Ordinance may apply – storage planning should clarify this at an early stage.
For storage technology, it must be assessed whether standard racks and containers are suitable for the substance in question, or whether special materials and coatings are required. On the IT side, the warehouse management system (WMS) must include blocking functions that prevent incompatible substances from being stored in the same area. Whether a hazardous materials storage area is operated internally or externally is a business decision: external vendors assume part of the compliance responsibility, though this does not fully resolve liability issues. As a general rule, requirements and best practices may vary by industry, substance, and federal state – coordination with the responsible authority and the company's hazardous substances officer is advisable.
