On January 15, 2016, the CDC issued a health advisory about the risk of Zika virus in light of reports of severe birth defects, including incomplete brain development, among infants of mothers infected during pregnancy in the Americas. Previously, this mosquito-borne virus, transmitted by Aedes species mosquitoes, had surfaced in Africa, Asia, and the Pacific Islands. NIOSH scientists also go to worksites when called to the field through the NIOSH Health Hazard Evaluation Program. In 2016, NIOSH scientists worked with partners nationwide to evaluate the causes of work-related illness, injury, and death in diverse industries, including firefighting, mining, construction, and oil and gas extraction.

Entrapments are a huge risk in underground mines. This happens when miners (or any other persons who have entered underground) survive the initial event of an accident, become trapped or lost in unknown and life-threatening locations after evacuation, and remain unaccounted for. At this point, every second counts, and emergency response is highly desired for any chances of saving survivors. The survival chances of the missing persons depend on how quickly they can be located. Rescue teams are often deployed to search for the missing persons underground. However, the rescue teams are forced to search in random and presumed areas of the mine. This is due to the unavailability of information pertaining to the whereabouts of the missing persons. Not only the provision of accurate locations, but various other types of information such as post-accident two-way communication can enhance the survival chances of the missing persons. This information can be provided by a fit-for-purpose missing person locator system. A wide variety of missing person locator systems are already commercially available, some are in testing phases and others in prototype and development phases. This includes tracking, tracing, location detectors and post-accident two-way communication systems. These systems have unique functionalities, capabilities and limitations; making it difficult for mines to select the most effective, applicable and suitable system specific to their mine. In this study, the user requirements for a fit-for-purpose missing person locator system were developed. The purpose of the user requirements was to provide a guideline to facilitate the system selection process. The user requirements can also be used as a tool to measure and evaluate the performance of the selected missing person locator system. The user requirements were also used to predict the success of the selected system under different missing person incident scenarios. The development of the user requirements showed a potential for many other benefits for missing person locator systems.
