Abstract:
In a method of monitoring lockout procedures, a first lockout device is secured with a first component in a lockout condition to block operation of the first component, and a corresponding first data signal is received, with the first data signal including at least a first identification code corresponding to the first lockout device. A second lockout device is secured with a second component in a lockout condition to block operation of the second component, and a corresponding second data signal is received, with the second data signal including at least a second identification code corresponding to the second lockout device. The first and second data signals are monitored to determine an order in which the first and second lockout devices have been locked out, which is compared with a predefined lockout procedure. An alert is provided if the order is inconsistent with the predefined lockout procedure.
