- Component involved
- PRD (burst disc)
- Failure mode
- premature activation & venting
- Initiating cause
- unknown
- Root CAUSE analysis
A material deficiency in that the disk was extensively corroded and failed under work working gas pressure. Contributing causes were inadequate quality control which failed to detect the corroded disk, and a test set-up which aimed the disk end of the bottle toward technicians.
