ODOR GENERATION ALARM AND METHOD FOR INFORMING UNUSUAL SITUATION

摘要

An object of the invention is to provide an odor generation alarm and a method for informing an unusual situation having a high attention attracting effect and a high degree of safety. An odor generation alarm (1) includes an odorant receptacle, a drive section (10), a detector (4) and a circuit section (7) which is a controller. The odorant receptacle contains an odorant. A concentration of the odorant in air at which a person can no longer tolerate a strength of smell is lower than a no observed effect concentration of the odorant. The drive section (10) causes the odorant to be emitted from the odorant receptacle. The detector (4) detects occurrence of an unusual situation, and outputs a detection signal. When the detection signal from the detector is inputted, the controller causes the drive section to emit the odorant in accordance with the detection signal.
