Prevention of Accidental Ignition (17.13)

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.
