Technical Working Group on Seveso Inspections

Under the Seveso Directive, EU Member States and EEA countries are required to inspect Seveso sites within a certain time period.  Inspection, and follow-up enforcement actions that might ensue, is one of the most powerful oversight mechanisms available to competent authorities.  The task of the inspector is to confirm that the site has demonstrated compliance with the Directive, in particular, the general obligation that the operator has taken "all necessary measures to prevent major accidents and to limit their consequences for human health and the environment".   The inspector must be convinced that the site operator understands the chemical hazards present on the site and their risk potential, that the operator has accordingly established appropriate control measures to prevent and mitigate potential accidents related to these hazards, and that the operator has a safety management system in place that ensures these control measures operate as intended and are improved over time based on new information resulting from change or feedback from the system.

It is without a doubt a challenging task.  More than 100 types of diverse industry activities falls under the Seveso Directive and the diversity and number of substances that represent a potential accident risk are higher still.  For this reason, for nearly two decades the EU Member States have provided strong support to an EU level technical exchange associated with Seveso inspection, managed by the JRC's Major Accident Hazards Bureau (MAHB).  MAHB runs two related activities supporting implementation of Seveso inspection obligations of Seveso implementing countries (which includes also EEA countries, Norway and Iceland).  These activities are the Technical Working Group on Seveso Inspections (so-called "TWG 2") and the Mutual Joint Visit Workshop Programme for Seveso Inspectors (the "MJV Programme"), that is managed by MAHB in consultation with TWG 2.  The exchange of information that takes place within these two activity spheres relates both to good inspection and enforcement practice as well as to good risk management practice that should be observed on Seveso sites.
