Questions: 16 · 10 minutes
1. Which item is an energy-isolating device?
A manually operated disconnect switch that physically separates the energy source
A machine's ordinary start push button
A software stop command on an operator screen
An emergency-stop button in the control circuit
2. A packaging-line operator does not service the machine but works in the area where maintenance lockout is being used. In this situation, the operator is generally considered what?
An affected employee
An outside contractor
A lockout coordinator
An energy-isolating device owner
3. What is the central purpose of lockout/tagout?
To record how long routine production interruptions last
To prevent unauthorized workers from entering the entire facility
To control hazardous energy during servicing and prevent unexpected startup or energy release
To identify equipment that has reached the end of its service life
4. Which feature most clearly indicates that a disconnect is capable of being locked out?
It is installed behind a removable equipment panel
It includes an illuminated stop button on the operator panel
It carries a printed warning label near the handle
It has a built-in or designated attachment point that accepts a lock in the isolating position
5. Which document should identify the steps for shutting down, isolating, blocking, and securing a particular machine?
The employee's general job description
The preventive-maintenance purchasing schedule
The machine-specific energy-control procedure
The facility's visitor sign-in policy
6. Before equipment is shut down for lockout/tagout, what communication is generally required?
Notify only employees who will personally attach locks
Post the maintenance schedule after shutdown without directly informing affected workers
Ask affected employees to test the controls before energy sources are isolated
Notify affected employees that lockout or tagout will be used and explain the reason
7. An outside contractor will service equipment alongside the host employer's workers. What should occur regarding energy-control procedures?
Only the contractor needs to know which procedures will be used
The host and outside employers should inform each other of their respective lockout/tagout procedures and restrictions
The host employer's procedure automatically replaces every contractor requirement without discussion
Coordination can wait until one employer needs to remove another worker's lock
8. What is a lockout device?
A device such as a keyed or combination lock that holds an energy-isolating device in a safe position
A production control that stops a machine at the end of each operating cycle
A label showing the date when equipment was last inspected
A barrier used only to mark the outer edge of a maintenance area
9. After all energy sources are locked or tagged out and stored energy is controlled, what should an authorized employee do before starting work?
Remove the locks briefly to confirm that each disconnect can move
Begin work immediately because applying a lock completes verification
Ask an affected employee to remain beside the start control
Verify that isolation and de-energization have been accomplished using the required checks
10. A press has been disconnected from electrical power, but its flywheel is still turning. What must happen before servicing begins?
The electrical disconnect must be briefly restored to test the flywheel
A warning tag must be placed on the start button while the flywheel continues turning
The operator must hold the stop button until the mechanic finishes
The stored mechanical energy must be restrained or allowed to dissipate, then isolation must be verified
11. What important limitation distinguishes a tagout device from a lockout device?
A tag may be used only on electrically powered equipment
A tag warns against operation but does not provide the physical restraint of a lock
A tag is intended mainly to track the employee's work hours
A tag automatically disconnects every energy source connected to a machine
12. Several mechanics work on the same locked-out machine. Which practice best reflects group lockout/tagout?
The most senior mechanic keeps the only key while others rely on that mechanic's protection
One shared tag lists the crew name, so individual protection is unnecessary
Each authorized employee applies or is represented by a personal lockout or tagout device under the group procedure
The machine operator guards the controls while the mechanics perform the work
13. A repair continues into the next shift. What should the shift-change procedure accomplish?
Remove every device at the scheduled shift time, even if the machine remains open
Let the incoming crew use the outgoing workers' names and keys until the repair is complete
Maintain continuous protection through an orderly transfer between outgoing and incoming employees
Replace personal devices with a warning sign during the handover
14. An authorized employee who applied a lock has left the site, and the lock must be removed. What is the appropriate approach?
Any available supervisor may cut it off immediately once production is waiting
Use the employer's documented removal procedure, including verification that the employee is absent and reasonable efforts to contact them
Ask an affected employee to remove it because that person operates the machine
Restart the machine first to determine whether the lock is still necessary
15. In lockout/tagout terminology, who is an authorized employee?
Any worker who normally operates equipment during production
A worker who locks or tags out equipment to perform servicing or maintenance
A manager who approves the purchase of energy-control devices
A safety representative who audits records but never services equipment
16. During normal production, a worker must bypass a guard and place a hand in the machine's danger zone to clear repeated jams. Which statement best applies?
Lockout/tagout may be required because the worker is exposed to unexpected energization or startup while servicing
Using the emergency-stop button alone provides the same physical isolation as lockout
A verbal warning to nearby operators replaces the need to assess hazardous energy
The work is routine production, so hazardous-energy controls never apply
