- An earthquake valve (or seismic valve) is an automatic method to shut off the low pressure regulated gas supply to a structure during a major earthquake and/or if a pipe is broken. These are applicable both to utility-supplied natural gas and to gas from liquefied petroleum gas (LPG). These small devices are installed on the property gas meter (usually between the utility company's metered installation and the structure piping) and are designed to instantly stop the natural gas supply in order to protect the structure if a gas leak or line break occurs during an earthquake. Fires or explosions due to gas line breaks can be more damaging than the actual earthquake itself. Gas supply companies recommend that the gas supply be cut off immediately if there is a smell of gas after an earthquake; if nobody is in place to do this, an unattended earthquake valve will instantly cut off the gas.

- ヒューズガス栓(ヒューズガスせん)は、ガス栓とガス器具の接続に使われるがはずれていたり、器具を接続をしていない側の元栓を開けるなどして、一度にガスが大量に流れるなどの異常がおきた際に、自動的にガスを遮断する構造になっている安全構造型ガス栓のことである。 プロパンガス事業者では伝統的に「ヒューズコック」の名称も使用されている。 (ja)
