ZEMA - http://www.umweltbundesamt.de/zema/eng/index.html
ZEMA is the Central Reporting and Evaluation Office for Hazardous Incidents and Incidents in Process Engineering Facilities (Zentrale Melde- und Auswertestelle für Störfälle und Störungen in verfahrenstechnischen Anlagen - ZEMA) in Germany. ZEMA records, evaluates and publishes in annual reports all events which must be reported to the authorities pursuant to the 12th Federal Immission Control Ordinance. Such reportable events are sub-divided according to their hazard potential into major accidents and disturbance of normal operation. The systematic recording and evaluation of events will provide information which acts as an important basis for a further development of the state of the art of safety technology. Between 1980 and 2000, 336 events were registered in the ZEMA database. Statistical evaluations are available for the period 1991 to 1999.
