PROBLEM TO BE SOLVED: To enable gas ejected from a damaged place of a metal gas conduit to be safely and quickly shut off, to facilitate recovery work after shut-off.SOLUTION: An ejection gas emergency shut-off tool 1 is configured to shut off, on an emergency basis, gas ejected from a damaged place Ps of a metal gas conduit P, and includes a work rod 3 having a length to such an extent as to enable remote work, and a permanent magnet 2 held at a holding part 3A provided at a tip of the work rod 3. The permanent magnet 2 or the holding part 3A has an adsorption surface 2A covering the damaged place Ps and magnetically adsorbed to a surface of the metal gas conduit P. To the adsorption surface 2A, an adhesion member 4 closely adhering to the damage place Ps is bonded.SELECTED DRAWING: Figure 2 【課題】金属ガス導管の損傷箇所から噴出するガスを、安全且つ速やかに遮断し、遮断後の復旧工事を簡易に行うことができるようにする。【解決手段】噴出ガス応急遮断具１は、金属ガス導管Ｐの損傷箇所Ｐｓから噴出するガスを応急的に遮断する遮断具であって、遠隔作業が可能な長さを有する作業棒３と、作業棒３の先端に設けた保持部３Ａに保持される永久磁石２とを備え、永久磁石２又は保持部３Ａは、損傷箇所Ｐｓを覆い金属ガス導管Ｐの表面に磁気吸着する吸着面２Ａを有し、吸着面２Ａに損傷箇所Ｐｓに密着する粘着部材４が付着させている。【選択図】図２
