Various standards are available to consider and address this problem, for example EN 60079-29-2 relating to the selection, installation, use and maintenance of devices for the detection and measurement of flammable gases and oxygen.<\/div><\/div><\/div><\/div><\/div>

Although these references are useful, they can be generic and too detailed or application-specific, which is why references are often irrelevant to most applications. The location of the sensor should be determined by experts who have knowledge in the field of gas dispersion combined with the knowledge of process engineers and personnel working in occupational safety.<\/div><\/div><\/div><\/div><\/div>

Detectors must be installed\u00a0<\/span>on place\u00a0<\/span>where gas is expected to be present. The places that require the most attention are near gas boilers, compressors, pressure vessels, pipelines and cylinders. Valves, gauges, flanges, pipe elbows, etc. are also the places where gas leaks are most likely to occur.<\/span><\/span><\/div><\/div><\/div><\/div><\/div>

There are several facts to consider when determining the location of a detector:<\/h5>
\n
    \n
  • For the detection of gases lighter than air (e.g., methane, ammonia) the detectors must be placed at a higher altitude<\/li>\n
  • For the detection of gases heavier than air (e.g. butane, sulfur dioxide), the detectors must be placed at a lower altitude<\/li>\n
  • Consider how the gas will behave at lower and higher airflow. If necessary, detectors can be installed in ventilation ducts<\/li>\n
  • Consider the influence of weather conditions on detector operation. For detectors installed outdoors, the installation of weather protection is recommended<\/li>\n
  • Use sunshade if the detector is installed in direct sunlight or in warm climates<\/li>\n
  • Consider procedural conditions. For example, butane is heavier than air, but if it leaks at high temperature and pressure, it can rise to higher altitudes.<\/li>\n
  • Consider easy access to the detector for easier maintenance<\/li>\n
  • When installing an IR detector in a beam, it is important to ensure that there is nothing that could block the IR beam<\/li>\n<\/ul>\n
