Abstract
An odor generation alarm and a method for informing an unusual situation having a high attention attracting effect and a high degree of safety are provided. An odor generation alarm includes an odorant receptacle, a drive section, a detector and a circuit section 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 causes the odorant to be emitted from the odorant receptacle. The detector 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.
