摘要： Embodiments relate generally to systems and methods for gas detection. A method may comprise operating a gas detector with a first alarm setting comprising a first predefined threshold; receiving sensed data of oxygen content in the ambient air; when the sensed data is below the first predefined threshold, activating an alarm; generating an acknowledgement request asking if the gas detector has entered an inert work zone; receiving a response from the user acknowledging that the gas detector has entered an inert work zone; deactivating the alarm; changing the alarm settings of the gas detector to a second alarm setting comprising a second predefined threshold; continuing to receive sensed data of oxygen content in the ambient air; when the sensed data is above the second predefined threshold, activating an alarm; and generating an acknowledgement request for the user asking if the gas detector has entered a normal operation work zone.

摘要： Embodiments relate generally to methods and systems for communicating, storing, and accessing a calibration and test certificate for a gas detector. A calibration and test certificate may verify that the gas detector has been tested and/or calibrated and can be operated in compliance with specific regulations. Embodiments of the disclosure include integrating the calibration certificate into the individual device, where it may be readily viewed by the user, a supervisor, or inspector to verify the compliance of the device. The certificate may be required to be verified when a user takes the gas detector to a worksite before work can begin. Therefore, storing the certificate on the device may simplify the process of accessing the certificate for the user and supervisor.

摘要： Embodiments relate generally to systems and methods for gas detection. A method may comprise operating a gas detector (102) with a first alarm setting comprising a first predefined threshold; receiving sensed data of oxygen content in the ambient air; when the sensed data is below the first predefined threshold, activating an alarm (110); generating an acknowledgement request asking if the gas detector has entered an inert work zone (122); receiving a response from the user acknowledging that the gas detector has entered an inert work zone; deactivating the alarm; changing the alarm settings of the gas detector to a second alarm setting comprising a second predefined threshold; continuing to receive sensed data of oxygen content in the ambient air; when the sensed data is above the second predefined threshold, activating an alarm; and generating an acknowledgement request for the user asking if the gas detector has entered a normal operation work zone (120).
