Can hydrogen sulfide gas pipelines really cross public areas?

The \"Regulations on the Safety Management of Hazardous Chemical Transportation Pipelines\" stipulate that it is prohibited for pipelines carrying highly toxic chemicals such as phosgene and chlorine to pass through public areas; strict controls are imposed on pipelines carrying other toxic gases such as ammonia and hydrogen sulfide when they pass through public areas. Does that mean that, under the condition of taking appropriate measures, hydrogen sulfide can still pass through? However, the \"Criteria for Identifying Major Potential Hazards in Production Safety Incidents in Chemical and Hazardous Chemicals Production and Operation Units\" states explicitly: 8. Pipelines carrying highly toxic gases such as phosgene and chlorine, as well as hydrogen sulfide, passing through public areas other than factory premises (including chemical parks and industrial parks). Since it is listed as a major hazard, is it actually possible to pass through or cross it? What are the reference standards, or what measures should be taken if possible? Thank you
Thank you to the original poster for raising this question. It seems there is some conflict, but considering the relevant regulations, it isn’t contradictory. General Order No. 43 was issued at the end of 2011 and came into effect in 2012. Although there is no ban on hydrogen sulfide pipelines passing through public areas, strict control has been explicitly required. The criteria for major safety hazards were issued by the State Administration of Work Safety at the end of 2017, and an interpretation of these criteria was provided in February 2018 by the Third Department of the then State Administration of Work Safety. It can be seen from the analysis that these criteria for identifying major hazards are all derived from provisions in laws, regulations, and standard rules. In other words, treating the “transmission of hydrogen sulfide pipelines through public areas” as a major hazard is also a measure for “strict control”. Requiring rectification as a major hazard is also a way to address historical issues. If it’s created anew, it won’t be allowed. An interpretation of the criteria for identifying major hazards is also provided, explaining the dangers of hydrogen sulfide; it is therefore necessary to further prohibit passage through public areas. The above is my personal understanding; if you have different views, feel free to discuss
Pipes for highly toxic gases such as phosgene and chlorine, as well as hydrogen sulfide, are permissible within factory areas (including chemical parks and industrial parks).

Outside the factory area, is it possible to cross inside the park?
