Determining whether goods require storage in a Seveso-compliant warehouse is not always straightforward.
A technical assessment that requires specific expertise in hazardous materials management is needed, as well as tools capable of accurately analyzing all available data.
The answer depends on the type of product, as well as on actual quantities stored, expected peak inventory levels and hazard classifications indicated in Material Safety Data Sheets (MSDS).
A common misconception is that the assessment should be based on average stock levels.
In reality, for Seveso regulatory purposes, the key parameter is the maximum expected storage level (peak inventory)—that is, the highest quantity of hazardous substances that may be present simultaneously within the facility.
This means that a warehouse may operate within regulatory thresholds for most of the year, yet exceed them during specific periods, such as seasonal demand peaks, high-volume supply cycles or temporary stock accumulation phases.
For this reason, it is essential to look beyond the current situation and include forecast scenarios and peak occupancy conditions in the evaluation.
Any reliable assessment must start with accurate product master data.
The first step is to collect the Safety Data Sheets (SDS / MSDS) for all products to be stored. These documents represent the official “ID card” of each chemical product, providing detailed information on hazard classifications, handling and storage requirements, and safety and risk management measures.
The next step is to develop a quantitative forecast of the volumes expected to be stored throughout the year, focusing on peak inventory scenarios.
Only by combining these two elements—hazard data and quantity projections—is it possible to determine whether a warehouse falls within the scope of the Seveso Directive.
Managing hazardous goods requires structured and controlled processes.
At CDM, in collaboration with our software development partner, we have implemented a dedicated module within our Warehouse Management System (WMS) to streamline and secure the evaluation process.
For each product, the system records the H-statements (hazard statements) defined by European regulations and included in the MSDS.
By combining these hazard classifications with the planned storage volumes, the system generates a simulation of Seveso category occupancy, allowing us to assess whether goods require storage in a Seveso-authorized facility, verify compatibility with CDM’s existing authorization limits, and identify potential compliance risks in advance.
Understanding in advance whether goods require a Seveso-compliant warehouse is essential to avoid operational disruptions, delays in project start-up and unexpected compliance costs.
It is not uncommon for companies to select a logistics provider that appears suitable, only to discover later that existing authorizations do not cover the required quantities or hazard categories.
A preventive assessment enables companies to properly plan their logistics strategy by identifying critical constraints early and selecting the most appropriate storage solution before goods enter the warehouse.
Choosing a logistics provider specialized in chemical logistics and hazardous goods management ensures accurate pre-assessment of regulatory requirements, higher operational safety standards and full compliance with applicable regulations.
At CDM, we support clients from the early stages of logistics project development by analyzing Material Safety Data Sheets, expected storage volumes and peak inventory scenarios in order to identify potential criticalities before operations begin.
Thanks to our experience in hazardous goods management and internally developed digital tools, we can rapidly and accurately assess the impact of goods on Seveso regulations and existing authorizations.
