  2. Gas detector - Wikipedia

    en.wikipedia.org/wiki/Gas_detector

    A gas detector can sound an alarm to operators in the area where the leak is occurring, giving them the opportunity to leave. This type of device is important because there are many gases that can be harmful to organic life, such as humans or animals. Gas detectors can be used to detect combustible, flammable and toxic gases, and oxygen depletion.

  3. Gas leak - Wikipedia

    en.wikipedia.org/wiki/Gas_leak

    A gas leak refers to a leak of natural gas or another gaseous product from a pipeline or other containment into any area where the gas should not be present. Gas leaks can be hazardous to health as well as the environment. Even a small leak into a building or other confined space may gradually build up an explosive or lethal gas concentration. [1]

  4. Natural Gas Act of 1938 - Wikipedia

    en.wikipedia.org/wiki/Natural_Gas_Act_of_1938

    The Natural Gas Act of 1938 had an enormous impact on the future of not only the interstate natural gas market, but the U.S. energy policy and regulation. The natural gas industry has undergone tremendous change since 1938, and pipeline companies no longer function as resellers of gas to local distribution companies (LDCs), the ideas behind the ...

  5. Leak detection - Wikipedia

    en.wikipedia.org/wiki/Leak_detection

    In order to analyse the concentration distribution present in the sensor tube, a pump pushes the column of air in the tube past a detection unit at a constant speed. The detector unit at the end of the sensor tube is equipped with gas sensors. Every increase in gas concentration results in a pronounced "leak peak". [6] [25] [26]

  6. Infrared open-path detector - Wikipedia

    en.wikipedia.org/wiki/Infrared_open-path_detector

    For portable use, detectors have also been made which use the natural albedo of surrounding objects in place of the retroreflector. The presence of a chosen gas (or class of gases) is detected from its absorption of a suitable infrared wavelength in the beam. Rain, fog etc. in the measurement path can also reduce the strength of the received ...

  7. Explosive gas leak detector - Wikipedia

    en.wikipedia.org/wiki/Explosive_gas_leak_detector

    A detector for propane is best placed down low near the floor, as propane is heavier than air. [3] A detector for natural gas (city gas) is best placed up high, near the ceiling. [3] Some detectors can detect both natural gas or propane, but this requires a compromise location. [4]

  8. Public Utility Regulatory Policies Act - Wikipedia

    en.wikipedia.org/wiki/Public_Utility_Regulatory...

    The law was created in response to the 1973 energy crisis, and one year in advance of a second energy crisis. Upon entering the White House, President Jimmy Carter made energy policy a top priority. The law started the energy industry on the road to restructuring. [1]

  9. Natural Gas Policy Act of 1978 - Wikipedia

    en.wikipedia.org/wiki/Natural_Gas_Policy_Act_of_1978

    Established maximum lawful prices for the sale of natural gas, which were phased out over a series of years, allowing market forces to set natural gas prices. [1] The Natural Gas Policy Act (NGPA) was the first building block in a plan from the Carter Administration to increase energy supply while reducing domestic consumption of energy. [2]
