1. A method comprising:
receiving, by a computing device from at least one image capture device, an image that includes a first optical pattern embodied on a surface of an article of personal protective equipment (PPE) and also includes a second optical pattern;
determining, by the computing device based at least in part on the first optical pattern and the second optical pattern, a spatial relation between the first optical pattern and the second optical pattern;
identifying, by the computing device based at least in part on the spatial relation between the first optical pattern and the second optical pattern, a safety condition that corresponds at least in part to the article of PPE; and
performing, by the computing device, at least one operation based at least in part on the safety condition.
