Hazardous energy control system

A hazardous energy control system for on-site lockout/tagout of equipment, comprising:

• a personal electronic device;
• wherein the personal electronic device includes a display screen and is configured to provide a user interface for a user to select equipment to lockout/tagout;
• wherein the personal electronic device is configured to determine, from a one-line drawing for the worksite, a set of energy isolation devices that a user will need to hang a lock on to render inoperable and be able to safely enter the selected equipment;
• wherein the user interface is configured to guide the user through a lockout/tagout process requiring the user to hang a lock on the determined set of energy isolation devices and thereby render the selected equipment inoperable and safe to enter;
• a voltmeter;
• wherein in guiding the user through the response to lockout/tagout process to hang a lock on a first one of the determined set of energy isolation devices, the user interface is configured to prompt the user to scan the voltmeter;
• wherein in response to the user scanning the voltmeter, the personal electronic device is configured to determine if the voltmeter is within a required calibration window;
• wherein in response to the voltmeter is within a required calibration window, the user interface is configured to guide the user through a Live Dead test on the first one of the determined set of energy isolation devices using the voltmeter.
