Abstract: In some examples, a computing device may receive audio data that represents a first plurality of utterances from a worker, wherein the first plurality of utterances represents at least one expression of the worker about a safety event. The computing device may select a set of safety context data that characterizes at least one of the worker, a worker environment, or an article of PPE. The computing device may determine, based at least in part on the safety context data and applying natural language processing to the first plurality of utterances, safety response data that represents a second plurality of utterances that is semantically responsive to the expression of the worker. The computing device may generate an output based at least in part on the safety response data that represents a second plurality of utterances that is semantically responsive to the expression of the worker about the safety event.

Abstract: A system includes a piece of equipment and an article of personal protective equipment (PPE) associated with a first worker. The PPE establishes a communications channel between the article of PPE and the piece of industrial equipment, receives status information from the piece of industrial equipment via the communications channel, notifies the worker via the PPE of the status information received from the piece of industrial equipment, receives a response from the worker via the PPE, and transmits to the piece of industrial equipment, via the communications channel and based on the response, commands that cause a change in operation of the piece of industrial equipment.
