1. A confined space monitoring process comprising:
providing a smart communication device having a readable identifier;
receiving an employee login into the smart communication device to match the smart communication device with an employee;
pairing the smart communication device with a wearable gas sensor device;
locating a portable area monitor device outside a confined space;
coupling a data transmission line from the area monitor device to an antenna inside the confined space to establish a wireless network inside the confined space;
receiving a scanned reading of the readable identifier into the area monitor to establish a presence of the employee at that confined space; and
obtaining data from one of the smart communication device or the gas sensor device from inside the confined space through the area monitor.
