A system comprising: an image capture device; and a computing device (16, 18, 32) communicatively coupled to the image capture device, the computing device (16, 18, 32) 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: retrieve, from the memory, first wearer-specific image data, the first wearer-specific image data comprising a visual representation of a first article of personal protective equipment having straps and/or a nose clip, positioned on a particular wearer in a way that satisfies at least one safety requirement related to fit of the PPE, wherein the first article of PPE positioned on the body part of the particular wearer comprises a first respirator positioned on a face of the particular wearer; receive, from the image capture device, second wearer-specific image data, the second wearer-specific image data comprising a visual representation of a second article of PPE positioned on the particular wearer, the second article of PPE of a same type of personal protection as the first article of PPE, wherein the second article of PPE on the body part of the particular wearer comprises a second respirator positioned on the face of the particular wearer; compare one or more visual features of the second wearer-specific image data to one or more visual features of the first wearer-specific image data, the features including at least one of shape, color, or reflectivity of the straps of the article of PPE, and/or the nose clip of the article of PPE; determine, based on the comparison of the one or more visual features of the second wearer-specific image data to the one or more visual features of the first wearer-specific image data, whether the second article of PPE satisfies the at least one safety requirement related to the fit of the second article of PPE; and output an indication of whether the second article of PPE satisfies the at least one safety requirement. an image capture device; and a computing device (16, 18, 32) communicatively coupled to the image capture device, the computing device (16, 18, 32) 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: retrieve, from the memory, first wearer-specific image data, the first wearer-specific image data comprising a visual representation of a first article of personal protective equipment having straps and/or a nose clip, positioned on a particular wearer in a way that satisfies at least one safety requirement related to fit of the PPE, wherein the first article of PPE positioned on the body part of the particular wearer comprises a first respirator positioned on a face of the particular wearer;
