1. During a lockout/tagout (LOTO) procedure, what is the primary
purpose of isolating hazardous energy sources before servicing
equipment?
A. To improve equipment efficiency during maintenance
B. To prevent the unexpected startup or release of stored energy that
could injure workers
C. To reduce electrical consumption during repairs
D. To comply only with manufacturer recommendations
Answer: B. To prevent the unexpected startup or release of stored
energy that could injure workers
Rationale: The fundamental objective of LOTO is protecting employees
from hazardous energy. Energy isolation prevents unexpected startup,
movement, or energy release that can cause crushing, electrocution,
burns, amputations, or fatalities during servicing and maintenance.
2. Which of the following best defines an "authorized employee"
under lockout/tagout procedures?
A. Any employee working near machinery
B. A worker trained and authorized to apply and remove lockout/tagout
devices
1
,C. The facility owner
D. Any contractor entering the facility
Answer: B. A worker trained and authorized to apply and remove
lockout/tagout devices
Rationale: Authorized employees perform servicing requiring energy
isolation. They receive detailed training on hazardous energy control
procedures and have authority to apply and remove lockout/tagout
devices.
3. An employee who operates machinery but does not perform
servicing is classified as:
A. Authorized employee
B. Safety engineer
C. Affected employee
D. Qualified electrician
Answer: C. Affected employee
Rationale: Affected employees operate or use equipment that is being
locked out. They must understand the purpose of LOTO and recognize
when equipment is unavailable for operation.
4. Which hazardous energy source is most commonly overlooked
during lockout procedures?
A. Electrical energy
B. Stored mechanical energy from springs or elevated loads
C. Thermal energy
D. Hydraulic pressure
Answer: B. Stored mechanical energy from springs or elevated loads
2
,Rationale: Residual mechanical energy frequently remains after power
isolation. Springs, flywheels, counterweights, elevated machine
components, and compressed mechanisms must be restrained or
released safely.
5. Which sequence correctly follows an effective lockout procedure?
A. Lock equipment, notify employees, verify isolation
B. Notify employees, shut down equipment, isolate energy, lock/tag,
release stored energy, verify isolation
C. Shut equipment down, perform maintenance immediately
D. Isolate electrical energy only
Answer: B. Notify employees, shut down equipment, isolate energy,
lock/tag, release stored energy, verify isolation
Rationale: The proper sequence ensures all hazardous energy sources
are controlled before maintenance begins. Verification confirms that
isolation has been successful.
6. Why must stored energy be relieved, restrained, or otherwise
rendered safe?
A. It improves equipment calibration.
B. Stored energy can unexpectedly release even after primary power is
disconnected.
C. It speeds maintenance.
D. It eliminates paperwork.
Answer: B. Stored energy can unexpectedly release even after
primary power is disconnected.
3
, Rationale: Residual pressure, gravity, springs, capacitors, flywheels,
hydraulic accumulators, and compressed gases remain dangerous after
energy isolation and must be safely neutralized.
7. Which lock should be used for lockout purposes?
A. Shared departmental lock
B. Personal lock assigned exclusively to one authorized employee
C. Combination lock known by supervisors
D. Any available padlock
Answer: B. Personal lock assigned exclusively to one authorized
employee
Rationale: Each authorized employee must maintain exclusive control
over their lock to ensure no one else can remove it and inadvertently
expose them to hazardous energy.
8. Tags used in tagout systems primarily serve to:
A. Physically prevent equipment operation
B. Warn against operating equipment but do not physically restrain
operation
C. Replace machine guards
D. Eliminate verification testing
Answer: B. Warn against operating equipment but do not physically
restrain operation
Rationale: Unlike locks, tags are warning devices. They communicate
danger but provide no physical restraint, making lockout the preferred
method whenever feasible.
