1. A personal protective equipment (PPE) training system comprising:
an image capture device; and
a computing device communicatively coupled to the image capture device, the computing device comprising one or more computer processors and a memory, the memory including instructions that when executed by the one or more computer processors cause the one or more computer processors to:
simulate a fitting of a personal protective equipment (PPE) article to a worker by:
controlling the image capture device to capture at least a first image of the worker;
selecting a digital model of the PPE article;
determining an alignment of the digital model of the PPE article 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 article in accordance with the determined alignment, wherein the digital model comprises an animation sequence demonstrating correct placement of the PPE article;
wherein the PPE article comprises a respirator mask, and wherein the animation sequence demonstrates performing a fit check of the respirator mask, wherein performing the fit check comprises covering a filter of the respirator mask and inhaling to identify leak paths.
