What does the acronym LOTO stand for?
Lockout/Tagout
Load Off Tool
Lift On Tag Off
Lock On Tool
LOTO stands for Lockout/Tagout, referring to procedures that isolate and secure energy sources (lockout) and communicate hazards (tagout). This process ensures machines remain in a safe state during maintenance or servicing. Implementing LOTO prevents unexpected energization and protects workers.
Who is considered an "authorized employee" under LOTO regulations?
A visitor to the facility.
A supervisor with no LOTO training.
An individual trained and designated to perform lockout/tagout procedures.
Any worker who operates the equipment during normal production.
Authorized employees are those who have received training in energy control procedures and are approved to apply and remove lockout/tagout devices. They are responsible for ensuring that hazardous energy sources are properly isolated. Affected employees are not considered authorized.
When should a lockout device be applied to equipment?
Before starting any maintenance or servicing work.
After completing the servicing work.
Only when equipment has failed.
Whenever production is paused.
Lockout devices must be applied before any maintenance or servicing begins to prevent the unexpected energization or release of stored energy. Applying the device after work or only when equipment fails does not ensure safety. Proper timing is critical for worker protection.
Which of the following is a required component of an energy control program?
Noise exposure assessments.
Written procedures for energy control.
Chemical inventory lists.
Ventilation testing reports.
OSHA requires a written energy control program that includes specific procedures for lockout/tagout to protect employees from hazardous energy. While noise assessments and ventilation tests are important safety measures, they are not part of the LOTO program.
Under OSHA regulations, what is the regulatory citation for the Lockout/Tagout standard?
29 CFR 1910.120
29 CFR 1910.178
29 CFR 1910.22
29 CFR 1910.147
The Lockout/Tagout standard is codified in OSHA regulation 29 CFR 1910.147, which outlines requirements for the control of hazardous energy. Other citations cover different topics such as hazardous waste operations (1910.120).
Which device is preferred for securing energy isolating devices during lockout?
Heavy-duty cable tie.
Adjustable wrench.
Durable padlock with unique keying.
Bungee cord.
OSHA requires lockout devices to be durable, standardized, and substantial enough to prevent removal without excessive force. Padlocks with unique keying meet these criteria. Tools like wrenches or bungee cords do not provide reliable isolation.
What minimum information must a lockout tag include?
The maintenance schedule.
The vendor contact details.
The name of the person applying the tag.
The equipment's serial number.
Lockout tags must identify the person who applied the tag to ensure accountability and communication. Equipment serial numbers or maintenance schedules are not required on the tag. Proper identification prevents unauthorized removal.
What is the correct method for verifying isolation after applying lockout devices?
Call a supervisor to confirm.
Attempt to start the equipment using its normal operating controls.
Visually inspect the lock only.
Shake the machine by hand.
Verification of isolation requires attempting to start the equipment with its normal controls to ensure all energy sources are effectively isolated. Simply inspecting the lock does not confirm that energy has been de-energized. This critical step prevents unexpected startup.
At what minimum voltage does OSHA Subpart S cover electrical hazards instead of the LOTO standard?
120 volts
50 volts
240 volts
600 volts
OSHA's LOTO standard (1910.147) does not apply to electrical hazards covered by Subpart S, which starts at circuits operating above 50 volts. Electrical energy controls follow Subpart S requirements instead of LOTO above this threshold.
In a group lockout situation, how should locks be applied when multiple authorized employees are involved?
Locks are not required in group situations.
One supervisor applies all locks.
Only the first employee applies a lock.
Each authorized employee applies and removes their own lock.
In group lockout, each authorized employee must apply their own individual lock to the energy isolating device to ensure that no one is exposed to energy release until everyone removes their own lock. This prevents accidental removal by another person.
Which device is specifically designed for group lockout applications to secure multiple padlocks on an energy isolating device?
Cable lockout
Circuit breaker lock
Tagout pouch
Lockout hasp
A lockout hasp allows multiple padlocks to be attached, enabling each authorized employee to secure their own lock during group lockout. Other devices like pouches or cable lockouts serve different purposes. The hasp design provides secure isolation.
What is the primary function of an energy isolating device?
Physically prevent the transmission of energy.
Alert nearby personnel with an alarm.
Record energy usage.
Measure energy levels.
Energy isolating devices are mechanical means, such as disconnect switches or valves, designed to physically prevent the transmission or release of energy. Their sole role is to isolate energy sources, not to record or measure energy.
During a shift change, which procedure must be followed for ongoing lockout/tagout applications?
Leave locks in place without documentation.
Supervisor personally re-verifies isolation.
Remove all existing locks and reapply new ones.
Use a documented transfer procedure to hand off locks and responsibilities.
OSHA requires a documented procedure for the orderly transfer of lockout/tagout devices between outgoing and incoming authorized employees during shift or personnel changes. This ensures continuity and accountability. Arbitrary removal or neglect of documentation is unsafe.
Who is responsible for conducting periodic inspections of lockout/tagout procedures?
An authorized employee not directly using the procedure.
A third-party auditor exclusively.
An affected employee.
The company CEO.
Periodic inspections must be performed by an authorized employee who is not directly involved with the specific energy control procedure being inspected. These inspections verify the effectiveness of the LOTO program. CEOs or affected employees are not specified by OSHA for this task.
When equipment has multiple energy sources, what is required under LOTO procedures?
Lockout of only the primary source.
Tagout without lockout.
Energy sources alternate by priority.
Isolation and lockout of each individual energy source.
For equipment with multiple energy sources, each source must be isolated and locked out to ensure complete de-energization. Failure to control a single source can result in unexpected energization. OSHA mandates this comprehensive approach.
What additional step must be taken to address stored (residual) energy after all energy isolation devices are locked out?
Apply a second tag only.
Release the primary lock.
Bleed, discharge, or block any stored energy (e.g., springs, capacitors).
Re-energize momentarily to verify isolation.
Residual or stored energy (in springs, hydraulic lines, capacitors, etc.) must be safely relieved, restrained, or dissipated after lockout is applied. Simply tagging or re-energizing is dangerous. This step prevents unexpected movement or energy release.
Under OSHA's minor servicing exception, which scenario does NOT require full lockout/tagout procedures?
An electrician replacing a motor.
A contractor installing new wiring.
A maintenance tech overhauling a gearbox.
A machine operator clearing a minor jam during normal production using an alternative safety measure.
OSHA allows minor tool changes and adjustments that are routine, repetitive, and integral to the production process to be performed without full LOTO if alternative measures (like machine guarding) provide effective protection. Clearing a minor jam fits this exception when done as part of normal duties.

Cheat Sheet

  1. Seven-Step Energy Control Procedure -

    Master OSHA's seven-step lockout/tagout protocol - Prepare, Shutdown, Isolate, Lock/Tag, Release Stored Energy, Verify Isolation, and Re-energize - to ensure systems remain inert during maintenance. Use the mnemonic "P SILVR" (Prepare, Shutdown, Isolate, Lock, Verify, Re-energize) to lock in these steps for your lockout tagout training quiz. Precise adherence drastically lowers the risk of unexpected equipment activation (OSHA 29 CFR 1910.147).

  2. Identifying All Energy Sources -

    Always map out every energy type - electrical, mechanical, hydraulic, pneumatic, chemical, thermal, and even gravitational - before starting maintenance. A checklist template from NIOSH or a color-coded flowchart can help categorize and track all potential energy hazards. Spotting hidden stored energy, like charged capacitors or pressurized lines, is key to passing any lockout tagout safety quiz.

  3. Proper Use of Lockout Devices vs. Tags -

    Locks physically prevent equipment operation while warning tags communicate status and hazards. ANSI/ASSE Z244.1 advises using durable, standardized lockout devices with unique keys and color-coded tags for clear identification. Remember, tags are strictly informational - never rely on a tag alone to replace a physical lock for the lockout tagout certification test.

  4. Zero-Energy Verification Techniques -

    After isolating energy, always verify zero energy by attempting to start equipment or testing outputs - known as "test-firing" - while keeping a safe distance. Use a multimeter to check voltage drop across electrical contacts, or measure pressure gauges to confirm no residual pressure. This verification step is crucial to acing your LOTO quiz and ensuring real-world safety.

  5. Periodic Inspections & Authorized Employee Training -

    OSHA mandates annual audits and refresher sessions for all authorized employees administering lockout/tagout procedures. Incorporate your facility's lockout tagout training quiz into recurring toolbox talks and document each session for compliance. Engaged, well-trained teams cut incident rates and boost confidence for any lockout tagout safety quiz or real-world application.
