Investigation of Failures (16.7)
Criticality: High
Progress: Not Addressed
Score: 40
DOT Relevance: §192.617
Description of Key Area
Investigation of
failures is addressed under Subpart L (Operations) of 49 CFR 192. As per the
current 49 CFR 192, procedures must be established “for analyzing accidents and
failures, including the selection of samples of the failed facility or
equipment for laboratory examination, where appropriate, for the purpose of
determining the causes of the failure and minimizing the possibility of a
recurrence.”
Discussion of Criticality
Investigation processes
of failures for hydrogen of hydrogen transportation systems need to be
established as new materials and construction methods are tested and deployed
so that increased understanding of failure modes can be obtained.
Discussion of Progress
SNL, in coordination
with NREL, is currently developing benchmark experiments and analysis strategy
for risk assessment of hydrogen systems. The application of risk assessment
studies is being cooperatively developed with the assistance of industry,
government agencies and laboratories, insurance companies, and other
stakeholders. ASME B31.12 will also address this area.
Recommendations
Risk assessments are an
essential tool for methodically evaluating technologies and their application. It
is necessary to establish standards and incorporate them by reference into the
federal code. These standards should include specific instructions regarding
investigation of failures.
