Issue with the gas detector legend in the drawing
Thread Content
The examples of combustible gases and toxic gases in the gas detector layout diagram provided by the design institute are shown as follows. If there is an oxygen content detector, does it need to be drawn separately? Is it still included in the combustible gases?
Also, should an oxygen level detector be included in the layout diagram for gas detectors used in the tripartite inspection? Thank you so much!
Regarding whether to install oxygen detectors, refer to GB50493-2019
Hello, if it needs to be set up, is it a separate identifier?

Should oxygen be considered toxic? For the legend, ask the design institute. If no separate legend is used, the type of measurement will also be indicated next to the tag number or legend
Okay, thank you! I see that fire protection equipment manufacturers classify oxygen as a toxic gas.
Look at the legend; it should be there. The methodology for compiling each section varies, and it seems that the standards do not specify this clearly. Some institutions use legends for differentiation, while others simply provide explanations next to them
Our design institute’s legend shows the two balls representing flammability and toxicity, as in the screenshot above...
