One or more noxious gas detectors disposed within a cabin of a vehicle are used by an analyzer to determine that a rate of increase of measured noxious gas exceeds a first threshold, or that a level of measured noxious exceeds a second threshold, or both; and to generate an alert output responsive to the determination. Optionally, the analyzer may take remediation actions by emitting or transmitting commands to the vehicle's control computer to stop or start the engine, start the air conditioning or heater, roll down windows, unlock doors, activate horns and lights, and even transmit alert messages to one or more recipients. In one embodiment, a window clip-on sign is provided with one or more sensors on an interior portion of the unit, and one or more alert means on an exterior portion to provide a portable and easy-to-use safety device.
