Disclosed is a headgear-type device for hazardous air quality warning and air quality improvement, wherein the device can collect biometric information of a worker, wired and wireless communications, and information about the quality of outside air around the worker so as to warn the worker of a hazard or improve air quality at the site. The headgear-type device for hazardous air quality warning and air quality improvement according to the present invention may comprise: a headgear-type biometric sensor which comes into close contact with the head of the worker so as to sense biometric information of the worker and thus allow measurements of the worker's physical conditions; a terminal which is wiredly or wirelessly connected to the headgear-type biometric sensor so as to transmit and receive the biometric information; and a server which receives the biometric information from the terminal, calculates, on the basis thereof, whether the biometric information is in a normal condition range, according to a program, and when the biometric information is not in the normal condition range, issues a warning to the worker by transmitting a warning state to the terminal.
