Disclosed are methods and/or a system of incident based camera device activation in a safety system of a structure having a fixed piping system implemented therein to supply breathable air thereacross. In accordance therewith, one or more sensor(s) associated with one or more component(s) of the safety system is integrated with a computing platform executing on a data processing device. Based on the integration of the one or more sensor(s) with the computing platform, one or more environmental parameter(s) of the one or more component(s) of the safety system is sensed. One or more camera device(s) in a vicinity of and/or on the one or more component(s) of the safety system is automatically activated based on determining, from the sensing, occurrence of an incident.

An exemplary system and method are disclosed for a respiratory protective device configured to continuously monitor, via an integrated sensor network embedded in the device's frame, the fit or proper particulate-filtering operation of the respiratory protective device. The system can ensure proper operation of respiratory protective device while providing monitoring and tracking of the fit to ensure personal safety for users wearing the device. In some embodiments, the system can monitor, track, and aggregate the data to present via a user interface to the user.

Example PPE fit systems are described that verify that a current fit of a PPE on a wearer is consistent with a previous fit test of the PPE on the particular wearer. During a fit test of a PPE, an image capture device captures an image of the wearer with the PPE that represents a verified reference for a fit of PPE of a same or similar type on the particular wearer. During a verification check, an image capture device captures an image of the wearer with the PPE. Visual features of the fit test image are compared with visual features of the verification image to determine whether the fit of the PPE on the wearer is correct. Differences between the visual features are alerted to the user, such as for correction, adjustment, or retest.

A testing apparatus for respirators and a method of using the same. The testing apparatus comprises a piston assembly including a piston movably disposed in a chamber and a motor assembly including a motor operably connected to the piston. The motor configured to move the piston in an exhalation direction producing a simulated exhalation and in an opposite inhalation direction producing a simulated inhalation. An amount of gas in the chamber increases during the simulated inhalation and decreases during the simulated exhalation. The method of using the test apparatus comprises the steps of causing the simulated inhalation and the simulated exhalation to determine whether the respirator meets at least one predefined requirement.

Augmented reality-based training systems are described that dynamically construct and render AR content based on physical attributes of a user to train the user to correctly fit one or more articles of a personal protective equipment (PPE) onto the user's body. In some examples, an AR system includes a display and a computing device having a memory and one or more processors. The memory includes instructions that when executed by the processors simulate a fitting of a PPE to a worker by capturing at least a first image of the worker; selecting a digital model of the PPE; determining an alignment of the digital model of the PPE to the first image of the worker; and outputting for display augmented reality content comprising a composite of a least a second image of the worker overlaid with the digital model of the PPE in accordance with the determined alignment.
