Recommendation 1 - Overhaul and replace the diaphragms on all cells showing low-purity results. Check on a routine basis the individual cell purity levels to monitor the deterioration of performance of individual cells. Certain…
No Lessons Learned, Specific Suggestions for Avoidance, or Mitigation Steps Taken.
Designs for high-tech systems/components evolve based on operating experience. The design changes should resolve identified deficiencies and are part of a continuous improvement process to increase reliability and productivity.
In any event, the lesson that should be derived from this incident is the fact that the explosion could have been avoided either by using an inert gas instead of air across the diaphragm, or by monitoring the hydrogen concentration in the upper…
As demonstrated by the fire discussed above, lack of adequate maintenance, system monitoring and oversight of maintenance of these facilities can contribute to the ignition of a fire that is difficult to extinguish and poses an extreme danger to…
