How can companies conduct effective detection of fugitive leaks?
Thread Content
In accordance with Article 10 of the **Guiding Opinions of the State Administration of Work Safety on Strengthening Leak Management in Chemical Enterprises** (formerly An Jian Zong Guan San [2014] No. 94): \"Comprehensive testing and maintenance for fugitive leaks in chemical equipment shall be carried out.\" Enterprises should, in accordance with the relevant standards and specifications for detecting fugitive leaks, regularly conduct leak inspections on areas prone to such leaks (such as sealing points on pipelines, equipment, pumps, etc.). Equipment that shows signs of leakage must be repaired or replaced promptly. Enterprises should implement comprehensive management of the entire leakage detection and repair process, and verify the seals after repairs in order to reduce or eliminate leaks. ” Question: 1. **In environmental management, there is a test called ‘Equipment Leak Detection and Repair (LADR)’ which is used to detect and repair leaks of organic volatile gases in the petrochemical industry. Is it mandatory for industries other than the petrochemical industry to carry out this test?** 2. If LADR testing is not mandatory for industries other than the petrochemical sector, how should chemical enterprises meet the requirements set by the Work Safety Administration to improve leak management? What instrument is suitable? What are the leakage standards? 3. What should enterprises that produce, use, and store corrosive chemicals such as acids and bases do?
It is also best to choose the appropriate leakage detection equipment based on the properties of your materials, and to set up alarm thresholds – this is necessary in accordance with safety regulations, especially for companies that store highly hazardous materials
This testing is definitely necessary for chemical companies. I would like to ask whether it is required to conduct LADR testing (which is costly!) ), if the company conducts this testing itself, what are the standards? Which type of testing equipment can meet the requirements, ensuring that acidic and alkaline chemicals do not emit any gaseous substances? Additionally, how should the testing be conducted to comply with the requirements set forth in Document No. 94 [2014] issued by the State Administration of Work Safety?
