Criticality: High Progress: Not Addressed Score: 40 DOT Relevance: §192.751
Description of Key Area
Prevention of accidental
ignition falls under Subpart M (Maintenance) of 49 CFR 192. §192.751 states
that “each operator shall take steps to minimize the danger of accidental
ignition of gas in any structure or area where the presence of gas constitutes
a hazard of fire or explosion…”
Discussion of Criticality
Appropriate standards
are necessary for prevention of accidental ignition of hydrogen pipelines.
Discussion of Progress
SNL is currently
conducting research on hydrogen release scenarios, cloud formation and
ignition, and flame jet characteristics.
Recommendations
Confirm whether or not
this topic will be addressed by ASME B31.12. Research into prevention of
accidental ignition for hydrogen pipeline applications must be expanded. This
may mean development of tools, equipment, sensors, training programs, etc.
Standards need to be developed and incorporated by reference into the federal
code.
