In industries such as gas, petroleum, chemical, and coal mine safety, combustible gas is one of the most common and frequently used gases. According to national fire department regulations, combustible gas detectors should be installed in locations where combustible gases are used or where there is a risk of leaks. In locations where installation is inconvenient, employees should be equipped with portable combustible gas detectors to ensure safe production and prevent fires or explosions. So, what are the installation standards for combustible gas detectors? Below, staff from Yiyuntian will explain.
Installation specifications for combustible gas detectors:
1. When the gas source is a gas with a relative density of less than 1 and the vertical distance between the release source and the ceiling exceeds 4m, a gas collection hood or a layered set of detectors should be installed. This is because if the building is too tall and no gas collection hood or layered set of combustible gas detectors are installed, the space will be too large and more combustible gas detectors will need to be installed.
2. The effective coverage radius of the combustible gas detector should be 7.5 meters indoors and 15 meters outdoors. One detector may be installed within the effective coverage area.
3. If the source of a flammable gas lighter than air is located in a closed or semi-closed factory building, a detector should be installed above the source and at the highest point in the factory building where flammable gas is likely to accumulate.
4. In locations where combustible gas detectors or toxic gas detectors and alarms should be installed, fixed types are preferred. When it is not feasible to install fixed types, portable combustible gas detectors should be provided.
