How to arrange and install gas detectors in different places?

Combustible or Toxic Gas Detectors are required to be installed in industrial places such as petroleum, chemical, metallurgical, and comprehensive pipe galleries, as well as commercial places such as catering, hotels, and supermarkets. However, many consumers often fail to monitor the instrument after purchasing it due to incorrect installation location, and may even damage the instrument, causing unnecessary losses.

So, how can consumers effectively layout and install combustible or toxic gas detectors for different places?

The detection points of combustible gas and toxic gas detectors should be comprehensively analyzed based on the physical and chemical properties of the gas, the characteristics of the release source, the layout of the production site, geographical conditions, environmental climate, the characteristics of the detector, the reliability requirements for detection and alarm, and the operation inspection route. The selection of locations where combustible gas and toxic gas are prone to accumulation, easy to sample and detect, and instrument maintenance should be carried out.

Installation of combustible/toxic gas detectors in production facilities

1.If the release source is located in the equipment area arranged in an open-air or open factory building, the horizontal distance between the combustible gas detector and any release source within its coverage area should not be greater than 10m. The horizontal distance between the toxic gas detector and any release source within its coverage area should not be greater than 4m; 2. If the release source is located in a closed factory building or a semi open factory building with poor local ventilation, the horizontal distance between the combustible gas detector and any release source within its coverage area should not be greater than 5m; The horizontal distance between the toxic gas detector and any release source within its coverage area should not be greater than 2 meters; 3. If the release source of flammable or toxic gases that are lighter than air is located in a closed or partially poorly ventilated semi open factory building, in addition to installing detectors above the release source, combustible or toxic gas detectors should also be installed at the highest point in the factory where gases are prone to accumulate.

Installation of combustible/toxic gas detectors in fire embankments

Detectors should be installed inside the fire barriers of liquid storage tanks that produce flammable gases, such as liquefied hydrocarbons, Class AB, and Class AB liquids. And comply with the following regulations: 1. The horizontal distance between the combustible gas detector and any release source within its coverage area should not be greater than 10m; 2. The horizontal distance between the toxic gas detector and any release source within its coverage area should not be greater than 4m.

Installation of combustible/toxic gas detectors in loading and unloading facilities

The loading and unloading facilities for liquefied hydrocarbons, Class AB, and Class B-A liquids should have detectors installed in accordance with the following regulations: 1. For railway loading and unloading platforms, one detector should be installed in each parking space on the ground, and the horizontal distance between the detector and the loading and unloading port should not exceed 10m; 2. The horizontal distance between the loading and unloading crane position and the detector at the Qizha loading and unloading station should not exceed 10m; The setting of detectors for pumps or compressors in loading and unloading facilities should comply with relevant regulations.

Installation of combustible/toxic gas detectors in filling stations

The detector setting of the liquefied hydrocarbon filling station should comply with the following regulations: 1. For closed or semi open bottle filling rooms, the horizontal distance between the filling port and the detector should be 5m to 7.5m; 2. Closed or semi open bottle storage warehouses shall comply with relevant regulations; An open bottle storage warehouse should be equipped with a detector every 15m-20m along the perimeter. When the total length of the perimeter is less than 15m, a detector should be installed; The horizontal distance between the buffer tank drainage outlet or valve group and the detector should be between 5m and 7.5m.

The installation of combustible/toxic gas detectors in the hydrogen filling room: For enclosed or semi open hydrogen filling rooms, detectors should be installed at the highest point of the room above the filling port where gas is easily trapped.

Installation of combustible/toxic gas detectors at loading and unloading docks: For loading and unloading docks that may emit combustible gases, one detector should be installed within 10 meters of the horizontal plane of the oil transfer arm.

The installation of combustible/toxic gas detectors in storage and transportation facilities: For other storage and transportation facilities for combustible and toxic gases, combustible gas detectors and/or toxic gas detectors should comply with relevant regulations.

Installation of combustible/toxic gas detectors for open flame heating furnaces: A combustible gas detector should be installed between the open flame heating furnace and the source of combustible gas release. The horizontal distance between the detector and the edge of the heating furnace should be 5m~10m. When there is a non combustible material solid wall between the open flame heating furnace and the combustible gas release source, a detector should be installed on the side of the solid wall near the release source. Proper and reasonable layout and installation of combustible/toxic gas detectors can enable gas detectors to perform at their best, providing a "protective umbrella" for enterprise safety production and safeguarding gas environment safety in various fields!
