PROBLEM TO BE SOLVED: To prevent specific gas from catching fire even in an environment where the specific gas is leaking without impairing workability.SOLUTION: Clothing that a user wears is provided with a clothing side circuit 12 including a fan 20 for generating an air stream that flows in the clothing by the driving force of a motor. When work is performed in an environment where gas is likely to be leaking, a gas alarm unit 30 is connected to the clothing side circuit 12 through connectors 18 and 46. The gas alarm unit 30 includes a gas concentration sensor 36 for detecting a gas concentration in an ambient environment, and a voltage detection unit 52 for monitoring the voltage of a power supply unit 34. When the gas concentration detected by the gas concentration sensor 36 is a threshold or more, or when the voltage of the power supply unit 34 detected by the voltage detection unit 52 is less than a predetermined value, a switch 48A is turned to an off state so as to stop an operation of the fan 20.SELECTED DRAWING: Figure 1 【課題】作業性を損なうことなく、特定気体が漏洩している環境でも特定気体に引火することを防止する。【解決手段】利用者が着用する衣服には、モータの駆動力により衣服内を流れる空気流を発生させるファン20を含む衣服側回路12が設けられている。ガスが漏洩している可能性のある環境で作業を行う場合、コネクタ18,46を介して衣服側回路12にガス警報器30が接続される。ガス警報器30は、周囲環境のガス濃度を検出するガス濃度センサ36と、電源部34の電圧を監視する電圧検出部52と、ガス濃度センサ36によって検出されたガス濃度が閾値以上になるか、電圧検出部52によって検出された電源部34の電圧が所定値未満になった場合に、スイッチ４８Ａをオフ状態に切替えることでファン２０の作動を停止させる。【選択図】図１
