Toxic gas alarms must be installed in the sulfuric acid fuming storage area; which specification can be referred to for this?
Thread Content
The sulfuric acid fuming storage area must be equipped with toxic gas detectors (sulfur trioxide) to continuously monitor gas concentrations and ensure production safety.
The Regulations on the Safety Management of Chemical Hazardous Materials, or the Measures for the Safe Management of Hazardous Chemicals, should be reviewed together with specific industry safety production standards, such as the safety production regulations for petrochemical enterprises. One can also refer to the specific regulations issued by ** or local authorities regarding the storage and handling of hazardous chemicals. .
The requirement that toxic gas alarms must be installed in the sulfuric acid fuming storage area can be found in the \"Design Standards for Detection and Alarm of Flammable and Toxic Gases in Petrochemical Industries\" (GB/T50493-2019). This standard specifies the design for the detection and alarm of flammable gases and toxic gases in petrochemical enterprises, including specific requirements for setting the measurement range and alarm values. Although this standard is primarily aimed at petrochemical companies, sulfuric acid fuming storage areas, as zones for storing hazardous chemicals, also need to comply with similar safety regulations.
I checked GB/T50493-2019, but no mention of sulfur trioxide was found.
50493 is responsible for LEL, while HG20660 and GBZ2.1 are related to toxicity; strict values from these two standards should be adopted, and installation shall be carried out in accordance with 50493
