- Root CAUSE analysis
- The INITIATING CAUSE was the accidental dropping of a CGH2 cylinders.
A CONTRIBUTING FACTOR is attributed by this very brief report to the degradation of the load-bearing capacity of the cylinder due to stress corrosion. Although not mentioned, it would be plausible to assume that this degradation was hydrogen-assisted.
The ROOT CAUSE could be a combination of a human error causing the dropping and lack of inspection on the integrity of the cylinder. Since the conditions under which the cylinder was transported are unknown, it is impossible to drawn conclusion on the contribution of job-related factors.
