MMC Safety & Compliance in Maintenance 2 — Questions and Answers
Question 1: Which OSHA standard specifically governs lockout/tagout (LOTO) procedures for the control of hazardous energy?
- 29 CFR 1910.147 (Correct answer)
- 29 CFR 1910.132
- 29 CFR 1910.219
- 29 CFR 1910.303
Correct answer: 29 CFR 1910.147
29 CFR 1910.147 is the OSHA standard titled 'The Control of Hazardous Energy (Lockout/Tagout)' that applies to maintenance activities.
Question 2: A maintenance technician is about to service a pneumatic press. After de-energizing, what additional step is required before beginning work?
- Verify zero energy state by attempting to operate the equipment (Correct answer)
- Apply a 'Do Not Operate' tag only
- Notify the supervisor and proceed immediately
- Remove all pneumatic lines from the press
Correct answer: Verify zero energy state by attempting to operate the equipment
Verification of zero energy state — by attempting to activate the equipment — is a mandatory LOTO step to confirm all energy has been released.
Question 3: Under OSHA's Hazard Communication Standard (HazCom), Safety Data Sheets must contain how many sections?
- 12
- 16 (Correct answer)
- 10
- 18
Correct answer: 16
The GHS-aligned HazCom standard requires SDS to follow a standardized 16-section format.
Question 4: What is the primary purpose of a Job Safety Analysis (JSA) in a maintenance context?
- Document equipment repair costs
- Identify hazards associated with each step of a maintenance task before work begins (Correct answer)
- Replace the need for a work permit
- Record the time spent on each maintenance activity
Correct answer: Identify hazards associated with each step of a maintenance task before work begins
A JSA breaks a job into steps, identifies potential hazards for each step, and defines preventive measures before work starts.
Question 5: Which type of confined space requires a written permit before entry by maintenance personnel?
- Non-permit-required confined space
- Permit-required confined space (Correct answer)
- Restricted access space
- Elevated work area
Correct answer: Permit-required confined space
A permit-required confined space has one or more serious hazards (atmospheric, engulfment, etc.) and requires a written permit, attendant, and rescue plan.
Question 6: A maintenance department's incident rate is calculated and found to be higher than the industry average. Which metric best describes this comparison?
- Total Recordable Incident Rate (TRIR) benchmarked against NAICS data (Correct answer)
- Mean Time Between Failures (MTBF)
- Overall Equipment Effectiveness (OEE)
- Preventive Maintenance Compliance (PMC)
Correct answer: Total Recordable Incident Rate (TRIR) benchmarked against NAICS data
TRIR is the standard OSHA metric for comparing workplace injury rates, and it is benchmarked against industry averages using NAICS classification data.
Question 7: When multiple employees perform LOTO on the same piece of equipment, which procedure should be used?
- The senior technician applies a single lock for the group
- Each authorized employee applies their own personal lock using a group lockout hasp (Correct answer)
- One tagout is applied and all employees sign it
- The supervisor holds the single lockout key
Correct answer: Each authorized employee applies their own personal lock using a group lockout hasp
Group LOTO requires a hasp so each authorized employee attaches their own personal lock, ensuring no one can restore energy while any individual's lock remains.
