Abstract
A system and/or method for increasing safety in areas in which people work and/or through which people travel that potentially may become blocked (e.g. mines, mineshafts, tunnels, etc.) is provided. In certain example embodiments, a system and/or method is provided wherein a sensor locates individuals who may be trapped and conveys their location(s) after an area becomes blocked. Sensors may be disposed throughout the area, located on individuals, etc. Sensors may be located behind protected coverings (e.g. glass), and they may locate individuals through, for example, low power, ultrasound, infrared techniques, etc. In certain example embodiments of this invention, one or more conduits may provide a supply of breathable air to individuals who may be trapped after the area becomes blocked.
