The company investigation revealed that the incident arose because insufficient water was added to the batch. This resulted in a rapid increase in temperature and evolution of hydrogen gas following the addition of aluminum powder in the last…
The incident was the result of a combination of factors leading to exceptional temperature conditions that were not taken into account in the mechanical design of the reactor. Corrective actions that were implemented by the plant management…
The following actions were proposed as a result of this incident:
