In 2017, AmmoniaKnowHow.com and UreaKnowHow.com introduced global open source risk registers for ammonia and urea plants. On January 1, 2023, the Risk Register Safety Incidents in Urea Plants contained 150 safety incidents. This presentation provides the detailed analysis of these incidents: In which plant sections and during which project phase do these incidents occur, which incidents occur most frequently, and which hazards have the highest risk factor.
The presentation elaborates the most critical safety hazards and recommends its prevention and mitigation measures. A surprising conclusion is that most safety hazards may lead to a sudden release of toxic ammonia. The paper provides suggestions on how to safely behave in a urea plant, and how to identify a maximum number of safety hazards.
