Is it necessary to install toxic gas alarms and related equipment for sulfur dioxide?

Thread Content

Sulfur dioxide is classified as a toxic gas of category 2.3; is it necessary to install toxic gas alarms and related facilities? Appendix B of the standard GB50493 does not mention sulfur dioxide; is it only highly toxic gases that require the installation of gas alarm systems? GB50493 lists only some substances; what should be done regarding those that are not listed?

GB50493_2019 3.0.1: When the concentration of toxic gases in the leaking gas may reach the alarm set value, a toxic gas detector should be installed

It’s definitely necessary; it’s not listed in the appendix, so it needs to be set according to the requirements in the main text.

It is required; Appendix B of GB/T50493-2019 specifies that it must be installed
