- United States
- Date
- Component involved
- PRD (burst disc)
- Failure mode
- premature activation & venting
- Initiating cause
- material degradation (generic)
- Root CAUSE analysis
The INITIATING CAUSE was the premature opening of the burst disc.
The ROOT CAUSE is unknown, because it is unknown if the disc failed due to lack of maintenance, wrong installation or wrong material choice.- Root causes
