Defining isolation points for equipment
Define isolation points for equipment to later isolate the equipment from its energy sources during a lockout/tagout procedure as part of a permit to work process. Isolating equipment from its energy sources helps to prevent further injury that may occur if the equipment or machinery is unexpectedly energized or starts up while maintenance or service work is being performed on the equipment by employees.
For example, if crews are performing maintenance on a machine, lockout/tagout safety procedures are observed which may involve isolating the machine from its power source by shutting off the power and placing a lock on the circuit breakers.
By defining isolation points, you indicate at which areas the equipment can be isolated from its energy sources to prevent injury from unexpected startup.
