This paper focuses on the instance segmentation of soft attributes on humans such as clothing and personal protective equipment at a hazardous workplace. We propose the use of soft biometric object classes from the Open Images V5 and DeepFashion2 datasets to pre-train a mask segmentation network to detect and segment personal protective equipment in the workplace. Preliminary results of our proposed model achieves a mean average precision, mAP50, of 61.7% with minimal optimization, resulting in very good segmentation of construction helmets, high visibility vests, welding masks, and ear protection in the workplace. Applications of the results from this paper include improving workplace safety in hazardous industries by providing a tool to ensure proper personal protective equipment usage while maintaining worker anonymity.
