When the concentration of oxygen detected by comparing the concentrations is equal to or less than the preset reference oxygen concentration, the notification module 17 may inform the worker that the oxygen concentration is lowered at the work site in response to the reference oxygen concentration. Then, since the concentration of oxygen in the work site is low, it is difficult for the worker to work, and thus, it is possible to prevent safety accidents by leaving the work site.

When the unit sensor 121 detects the concentration of the harmful gas as detection information, the information collection unit 131 collects the concentration of the harmful gas at the work site, and the safety control unit 33 determines the concentration of the detected harmful gas and the When the concentration of the harmful gas detected by comparing the set standard harmful concentration is equal to or greater than the preset standard harmful concentration, the notification module 17 notifies the worker that the concentration of the harmful gas increases at the work site in response to the standard harmful concentration. can Then, since it is difficult for the worker to work due to the high concentration of harmful gases in the work site, safety accidents can be prevented by leaving the work site.

A safety control unit 33 may be included. The information generated by the safety controller 13 is transmitted to the server unit 40 to be described later so that a manager can monitor it.

In the case of this safety controller 13, it is possible to predict the risk level of the work site by risk prediction information, thereby preventing workers from being exposed to dangerous situations, allowing workers to leave the work site in preparation for danger, and safety accidents can prevent
