Abstract
A handheld, portable device (20) is used to store data that indicates an operator was sufficiently close to each of a plurality of components during a safety inspection to actually inspect the components. The portable device includes a sensor (46) that detects tokens (12, 16, 24), such as radio frequency identification tags, which are affixed adjacent to the components. Messages (58) appearing on a display (40) of the portable device prompt the operator to proceed to each checkpoint, determine a state of the component disposed there, and if the component is not operating properly, indicate a plurality of predefined conditions from which the operator can choose to identify the observed condition of the component. The state and condition of each component entered during the safety inspection are stored as data that are subsequently transferred to a remote data storage site over a wire or wireless link.
