Abstract
Systems and methods for monitoring elevations of a set of workers at a job site include reference devices for capturing barometric pressures at different installation elevations on a structure and portable barometric pressure sensors carried by the workers. An atmospheric pressure offset may be calculated using the reference barometric pressures and installation elevations. The atmospheric pressure offset may be applied to atmospheric pressure measurements captured by the barometric pressure sensors carried by the workers to determine worker elevations. The worker elevations may be converted to corresponding floors of the structure.
