PPE detection is the use of computer vision to check automatically whether people in a camera's view are wearing required protective equipment, such as high-visibility vests, hard hats or safety shoes.
Cameras on fixed mounts or on trucks run a model, on the device or on a server, that recognizes people and classifies the equipment they wear. Results feed dashboards, alerts at area entrances or, in some setups, access gates. Detection quality depends on lighting, camera angle, distance and how distinct the PPE looks; a hi-vis vest is easier to detect than safety glasses or hearing protection.
PPE detection checks compliance with a rule; it does not decide what PPE is needed. Under 29 CFR 1910.132 the employer must assess hazards, select suitable PPE and train workers, and PPE remains the last tier of the hierarchy of controls. In forklift areas the useful targets are usually hi-vis clothing and entry into restricted areas, because no PPE prevents a struck-by injury. Camera use also raises privacy questions, and at EU sites the GDPR applies. See PPE detection systems.
