Is it mandatory to install emergency shut-off valves for Class 4 major hazard sources?
As required, emergency shut-off valves must be installed only for liquefied gases and **liquids.
Personally, I think it’s better to use the high-quality version, as it reduces the workload
The regulations do not impose such a requirement; it should be installed according to actual conditions
**Notice from the General Administration of Work Safety on Issuing Guidelines for Curbing Serious Accidents Involving Hazardous Chemicals and Fireworks and Firecrackers, An Zong Guan San [2016] No. 62: (4) As of January 1, 2017, all hazardous chemical storage areas that constitute Class I or Class II major hazard sources and do not have an emergency shutdown (emergency isolation) function must cease to be in use； (5) As of January 1, 2017, all chemical storage areas that represent major hazard sources and fail to achieve remote, continuous monitoring of parameters such as temperature, pressure, and liquid level, as well as those that do not have detection and alarm systems for leaks of flammable and toxic gases, must cease to be in use ； You’re at level 4; it’s not mandatory yet
Thank you~ thank you~;P. Following your guidance, I went to the website of the State Administration of Work Safety to check Order No. 62: handshake
