Last week during the AICHE Ammonia Safety Conference in Brooklyn, UreaKnowHow.com contributed to this important and reputable conference. Together with Tech Safety Group (www.techsafetygroup.com), a Technical Paper was prepared discussing the potential hazards involved in a 316L Urea Grade Urea Reactor. 
These potential hazards are listed in an Open Source Global Risk Register.
The Risk Register is a collection of possible risks that can occur in such a urea reactor and includes the related mitigation measures: 43 hazard risks are identified and 39 recommendations are defined. These recommendations are applicable in any phase of the life of such a reactor, starting in the design phase, via the fabrication phase, construction phase, operation, shut down and start up phase including its maintenance (for example which points to inspect in a urea reactor).
This list forms a perfect learning tool about why certain operating and maintenance procedures are done as they are done. So one learns Why… instead of only What …. Go to Risk Registers
