A gas detector includes environmental condition detection circuitry that includes one or more sensors, data processing circuitry, and wireless communication circuitry. The gas detector is configured to be carried by a user. The environmental condition detection circuitry detects the presence or lack of presence of a particular gas in a vicinity of the gas detector and further detects a temperature in the vicinity of the gas detector and communicates detection data to the data processing circuitry. In response to detection of a hazardous temperature condition, the data processing circuitry of the gas detector provides an alert notification to the user carrying the gas detector. Also disclosed is an alert system including multiple gas detectors in which a first gas detector communicates an alert to a second gas detector via wireless communication, and in response, the second gas detector transmits the alert to another gas detector or device via wireless communication.

Unsafe work condition temperature alerts in portable gas detectors

An alert system and method includes at least first and second detectors that each includes environmental condition detection circuitry, data processing circuitry, and wireless communication circuitry. The first and second detectors are respectively carried by first and second users. The first and second detectors detect environmental conditions in a vicinity of the respective detectors and communicate detection data to the respective data processing circuitry. In response to detection of a hazardous environmental condition by the first detector, the first detector provides an alert notification to the first user and communicates the alert to the second detector via wireless communication, and in response to receipt of an alert from the first detector, the second detector transmits the alert to another detector or device via wireless communication. A communicated or transmitted alert may include an incrementing indicator of a number of hops or levels of transmission of the alert.
