Abstract
A method begins by a processing module obtaining a set of identifiers (IDs) corresponding to a set of user devices, wherein each user device of the set of user devices is associated with a corresponding safety status level. For each identifier (ID) of the set of IDs, the method continues with the processing module generating a safety status request that includes the ID, outputting the safety status request to a user device of the set of user devices that corresponds to the ID, receiving a safety status response of a set of safety status responses, wherein the safety status response includes a corresponding safety status level of one user device of the set of user devices, and indicating the safety status level of the safety status response when an ID of the safety status response compares favorably to at least one ID of the set of IDs.
