Hazardous condition warning indications are transmitted from a site to a remote location on a conventional audio communication link. A variety of hazardous conditions including unconsciousness or inebriation of a workman at the site or his exposure to dangerous materials may be sensed and identifying information indicative of the source or location of the irregularity sensed may be transmitted to the remote location. A convention hand-held transceiver equipped with hazardous material sensors and sensors responsive to indications of potential impaired functioning of the individual are illustrated as an exemplary embodiment.
