Negative pressure reusable respirator system for safety event detection

A system comprising:

• a negative pressure re-usable respirator configured to be worn by a worker and to cover at least a mouth and a nose of the worker to form a sealed space formed by a face of the worker and the negative pressure re-usable respirator, wherein the negative pressure re-usable respirator comprises at least one contaminant capture device configured to remove contaminants from air as the air is drawn through the contaminant capture device when the worker inhales, and wherein the at least one contaminant capture device is configured to be removable from the negative pressure re-usable respirator;
• a pressure sensor configured to generate pressure sensor data indicative of an air pressure in the sealed space formed by the face of the worker and the negative pressure re-usable respirator;
• an infrared sensor configured to generate infrared sensor data indicative of a distance between the face of the worker and the negative pressure re-usable respirator;
• and
• at least one processor configured to:
• determine, based on the pressure sensor data and the infrared sensor data, whether a breach of the sealed space formed by the face of the worker and the negative pressure re-usable respirator has occurred;
• perform one or more actions in response to determining the breach has occurred.
