Air Monitor is a mobile application solution for fire service/fire investigators designed to provide a consistent and repeatable process to evaluate the post fire atmospheric conditions in order to determine whether a lower level of respiratory protection can be utilized while working in the space. This process was developed to comply with NFPA requirements for firefighter safety as well as Washington State Administrator Code 296-305 Safety Standards for Firefighters. Users of Air Monitor have access to a dashboard which provides the reporting and results which may be attached to other documents or retained as part of a personal exposure record.
