Abstract: A fit detection system for a respiratory protection device is presented that includes an infrared camera that captures an image sequence of a user wearing the respiratory protection device. The system also includes a temperature change detector that analyzes images in the image sequence and detects a temperature change profile of the respiratory protection device. The system also includes a communication component that communicates a fit indication based on the detected temperature change profile.
