What is the next step if you are not able to verify that an energy source is completely de-energized or isolated?
Stop and notify supervisor. Get the QSR back and perform isolation and verification from the start
You notice that a potential hazardous energy source hasn't been accounted or while in the middle of performing a high profile job. What do you do?
Stop the job and go through the LOTO/ISO procedure and verification from the beginning with the QSR
What are some verification methods to ensure that a piece of equipment or machinery is completely de-energized?

Name one of the four MINIMUM required procedural requirements that must be a part of an employer's Hazardous Energy Control Plan?
a) Intended use of the procedure. b) Specific procedural steps for shutting down, isolating, blocking, and securing machines or equipment to control hazardous energy. c) Specific procedural steps for the placement, removal, and transfer of lockout devices or tagout devices, and a description of who has responsibility for them. d) Specific requirements for testing a machine or piece of equipment to determine and verify the effectiveness of lockout devices, tagout devices, and other energy control measures.
The Lockout/Tagout standard includes requirements for releasing machines or equipment that have been locked out or tagged out prior to restoring energy to the equipment and using it.
