Lockout and Tagout (LOTO) is a safety procedure used to ensure that machines and equipment are properly shut off and not able to be started up again before the completion of maintenance or repair work.
Importance in Industrial Safety
Imagine working on a machine and it starts up unexpectedly—LOTO prevents such dangerous surprises. It’s about safeguarding lives, reducing accidents, and ensuring that energy sources like electricity, hydraulics, and pneumatics are isolated.

10 Most Common LOTO Interview Questions and Answers
Question 1: What is LOTO and why is it important?
Answer:
LOTO is a safety protocol that prevents accidental startup of machinery during maintenance. It protects workers from electrical shocks, burns, or being caught in moving parts.
Question 2: What are the key steps in a LOTO procedure?
Answer:
- Prepare for shutdown
- Notify affected employees
- Shut down equipment
- Isolate energy sources
- Lockout/Tagout devices
- Release stored energy
- Verify isolation
Question 3: What equipment is used in LOTO?
Answer:
- Padlocks
- Lockout hasps
- Tagout labels
- Valve lockouts
- Circuit breaker lockouts
- Plug lockouts
Question 4: Who is authorized to perform LOTO?
Answer:
Only trained and certified personnel—usually maintenance staff or safety technicians—are allowed to perform LOTO.
Question 5: What are the consequences of failing to follow LOTO procedures?
Answer:
- Serious injuries or fatalities
- Legal penalties
- Equipment damage
- Loss of company reputation
Question 6: Can you explain group LOTO?
Answer:
Group LOTO is used when multiple workers are involved. Each worker applies their personal lock to a group lockbox, ensuring no one removes a lock without everyone being safe.
Question 7: How is LOTO different from tagout only?
Answer:
Tagout uses a warning tag, but no physical lock. Lockout physically prevents machinery operation, making it more secure. OSHA prefers lockout over tagout unless it’s not feasible.
Question 8: What is a Zero Energy State?
Answer:
It’s the condition where all energy sources (electrical, hydraulic, pneumatic, etc.) have been disconnected, released, and verified as inactive.
Question 9: What documentation is required for LOTO?
Answer:
- Energy control procedure
- LOTO logbook
- Authorization forms
- Training records
- Equipment isolation diagrams
Question 10: How often should LOTO training be conducted?
Answer:
Annually at a minimum. However, retraining should happen when new equipment is introduced, procedures are updated, or when employees show signs of non-compliance.
