Hydrogen sulfide (HS) is a bright, highly toxic, weakly acidic gas with a rotten egg smell and slightly heavier than air. Its presence is extremely harmful to the health and life of shallow-water oil workers and oil facilities. In order to prevent such hazards, this standard is specially formulated.
This standard is proposed by China National Petroleum Corporation. This standard is under the jurisdiction of the Oil Industry Safety Professional Standardization Technical Committee. The drafting units of this standard are: Safety and Environmental Protection Department and Technical Supervision Department of Shengli Petroleum Administration. The main drafters of this standard are Lu Shihong, Lü Mingchun, Ren Qinghe, Cao Deguo, Wei Zhonghua, Cao Zhixin, and Fan Gu
Petroleum and Natural Gas Industry Standard of the People's Republic of China The safety provisions for hydrogen sulfide environment in shallow water petroleum operations This standard specifies the basic safety requirements for hydrogen sulfide protection in shallow water petroleum exploration and development operations.
