Flame work gas analysis indicates a certain type of gas
Thread Content
Hello, everyone who is into the sea. Some time ago, there was an inspection report in which experts from the Safety Committee suggested that the type of gas to be detected for flammable gas testing must be specified Was this established by that standard specification or is it a local requirement? For enterprises, the main flammable gas components vary in each production section; therefore, when conducting professional quality inspections, different types of flammable gas detectors are required, and those used for field testing must also be checked regularly. It increases the workload considerably.
The requirement to detect a specific flammable gas during hot work usually stems from **safety production standards or industry regulations**. This requirement is intended to ensure safety at the work site and prevent fires or explosions. The main combustible gas components may indeed vary across different work areas; therefore, it is essential to use appropriate combustible gas detectors for various scenarios. Although this may increase the workload for businesses, in the long run it can effectively ensure the safety of employees and production safety. To determine which specific standard or specification should be applied, it is recommended to consult the local work safety supervision and management authorities or industry associations for detailed guidance. .
Yes, thank you very much for your answer. I was just wondering if there are any relevant provisions to define this
Regarding the specific provisions concerning particular flammable gases in hot work operations, you can refer to relevant laws and regulations such as the Work Safety Law of the People’s Republic of China, as well as industry standards like the Safety Regulations for Operations in Fire-Hazardous Environments. These documents usually specify in detail the safety measures to be followed during the operation, including the types of gases that must be detected. Furthermore, depending on the region, there may be specific local regulations or standards. It is recommended to contact professional agencies or local safety supervision departments for the most accurate information and guidance. .
Thank you. I couldn’t find the procedures for working in hazardous environments that you mentioned. Do you have them? Could you send it? Thank you
I think the original poster is asking a good question – different gases are involved in the inspection of each process, so does that mean every one of them needs to be analyzed? Chromatographic analysis is now commonly used for gas analysis, and this method involves chromatography columns, standard samples, and standard curves. Just the testing phase requires a significant amount of manpower and resources. **The standards specify which gases should be analyzed in order to avoid the situation where everyone analyzes the same gases; if an explosive gas goes unnoticed and causes an explosion, it would be a serious mistake. Therefore, it is specified that flammable gases should be analyzed. In gas analysis tests, one of the testing methods used with Otsu gas analyzers is the ignition test. If any mixed gas triggers an ignition reaction during this test, work involving fire must be stopped, thereby avoiding the problem of not knowing which among the countless possible flammable gases needs to be tested. However, due to the poor accuracy of Otsu gas analyzers in determining gas composition, this function is often overlooked, and such testing methods are forgotten by most people.
Thank you. Can current analytical detection technologies distinguish the active components of flammable gases within 30 minutes? This is a key aspect of business management
This problem can be solved using the pop test of an Austen gas analyzer.
In hot work analyses, it is necessary to specify the exact types of gases to be detected for combustibility. This requirement is typically established in accordance with **relevant regulations and standards, with the aim of ensuring the safety of hot work and preventing fires and explosions. Specifically, in accordance with the relevant provisions of GB 30871-2014 \"Safety Specifications for Special Operations in Chemical Production Units\", the concentration of combustible gases in the operation area or at the location where welding will take place should be measured before carrying out such operations, and the type of combustible gas to be tested must be specified. This is because different combustible gases have different lower explosion limits and combustion characteristics, thus requiring targeted detection and analysis. In practical operations, the range of flammable gases to be detected during hot work usually includes, but is not limited to, flammable and explosive gases such as natural gas, liquefied petroleum gas, hydrogen, and ammonia. The testing items mainly include gas composition analysis, concentration measurement, pressure monitoring, and leak detection, etc., to ensure that the concentrations of these gases remain within safe limits, thereby protecting people’s lives and property. In addition, local governments and industry sectors may also establish more specific requirements and standards for combustible gas detection, based on the local or industry-specific conditions. Therefore, before carrying out hot work, it is necessary to fully understand and comply with **relevant regulations, standards, as well as local and industry-specific requirements, to ensure the safety of such work.
Thank you, I’m checking the specific requirements and interpretations for version 30871-2022
