Detection of toxic flammable gases
Thread Content
What standards should be followed for the detection of toxic and flammable gases, or what aspects need to be taken into consideration during the actual design process?
**Standard GB 50493-2009: Design Code for Detection and Alarm of Flammable and Toxic Gases in Petrochemical Industries. GBZT 223-2009: Code for Installation of Detection and Alarm Devices for Toxic Gases in Workplaces. Industry standard SH3063-1999: Design Code for Detection and Alarm of Flammable and Toxic Gases in Petrochemical Enterprises. When designing, pay attention to the proper spacing between various components as well as wind direction. If both flammable and toxic gases are present, detectors for toxic gases should also be installed. The height of the detectors should be determined based on the specific gravity of the flammable/toxic gases being released. Add the rest downstairs
The industry standard SH3063-1999, \"Design Code for Detection and Alarm of Flammable and Toxic Gases in Petrochemical Enterprises,\" has been repealed, and it has been replaced by the **standard GB 50493-2009, \"Design Code for Detection and Alarm of Flammable and Toxic Gases in Petrochemical Industries\"； GB50093-2002 Code for Construction and Acceptance of Automatic Instrumentation Projects – General Installation Design ； HG-T 20636.5-1998 Division of labor in design among automation engineering, telecommunications, pump and compressor engineering, and safety (fire protection) engineering – Division of tasks ； List of Highly Toxic Substances ； GBZ 2-2002 Occupational Exposure Limits for Hazardous Factors in the Workplace ； GB15322.1-2008 specifies point-type combustible gas detectors with a measurement range of 0~100% LEL; standards such as GB3836.1/.2, etc. – though small in size, they have all the necessary functions.
The 3rd floor is awesome; are the materials comprehensive? Great job!
