Criticality: High Progress: Addressed, Not Adequately Score: 20 DOT Relevance: §192.736
Description of Key Area
Section 192.736 (Compressor Stations: Gas Detection) of Subpart M
(Maintenance) of 49 CFR 192 states that “…each compressor building in a
compressor station must have a fixed gas detection alarm system…….”
Discussion of Criticality
The gas detection system should continuously monitor the
compressor building for a certain concentration of hydrogen in air. This
concentration must be established. There is an ongoing discussion in the
hydrogen community regarding the need to distinguish between hydrogen and other
combustible gases in certain applications.
Discussion of Progress
This topic will be addressed by ASME B31.12 as part of compressor
station requirements.
Recommendations
The need for hydrogen-specific sensors at compressor stations
needs to be evaluated. If required, current sensor development efforts should
be evaluated for applicability. Standards must be established relating to
hydrogen compressor stations. These standards must be incorporated by reference
into the federal code.
