Abstract: A system and method of monitoring zones for alarm conditions and automatically alerting individuals in a plurality of zones about the safety of a particular zone is provided. The method includes providing a site map of a predefined area, configuring a plurality of zones in the predefined area, receiving ambient condition data and location data from a plurality of wireless devices located in the predefined area, computing an alarm level for each zone in the plurality of zones based on the received ambient condition data and location data, and transmitting alert notifications to the plurality of wireless devices. The alert notification sent to each wireless device is based on the computed alarm level of the zone in which that wireless device is located relative to the computed alarm level of the other zones in the plurality of zones.

Abstract: A system and method of associating, assigning, and authenticating users with and to a personal protective equipment device is provided. A method can include receiving biometric data, processing the received biometric data, and based on the processing, associating a user with a personal protective equipment device.

Abstract: A method and apparatus including the steps of a first file defining a set of geographic coordinates of a work area, a second file defining a set of geographic coordinates of a mustering zone, a plurality of portable wireless sensors, each having a geographic positioning system, each carried by a person within the work area and each determining its geographic location, an environmental monitoring system detecting a threat within the work area, a processor detecting a location of each of the plurality of wireless sensors and a processor generating an alert for each of the plurality of portable sensors that have not arrived within the mustering area within a predetermined time after the detected threat.

Abstract: A method and apparatus for detecting hazardous gases.

Abstract: A system for monitoring a gas leakage incident in an industrial facility comprises a local area network, and a plurality of closed-circuit television cameras operatively connected to the local area network. The closed-circuit television cameras are positioned to provide video images of plural areas in a facility, with a central station operatively connected to the network for receiving video images from the television cameras. As plurality of gas detectors positioned in plural areas of the facility are operatively connected to the local area network, with each gas detector being operable to provide a signal which indicates occurrence of a gas leakage incident. Real-time monitoring of one or more gas-leakage incidents facilitates efficient evacuation of operating personnel, with the system preferably configured to automatically direct one or more of the closed-circuit television cameras to the area from which a gas leakage signal originates.

Abstract: A method and apparatus for detecting hazardous gases.

Abstract: An apparatus to obtain zoned real-time gas concentration and location information from a plurality of gas detectors and provide compliance information along with exposure trends and warning information. Acquired concentration and location information can be stored in a common memory unit for efficient trend analysis and generation of compliance information.
