Correct answer: Documenting incidents where no injury or damage occurred but could have
A near-miss is an unplanned event that did not result in injury or damage but had the potential to do so, and reporting it enables preventive corrective action.
Question 2: OSHA's general duty clause requires employers to:
- Inspect every machine monthly without exception
- Keep the workplace free from recognized serious hazards (Correct answer)
- Provide free meals to all production employees
- Hire a safety officer for every 50 employees
Correct answer: Keep the workplace free from recognized serious hazards
Section 5(a)(1) of the OSH Act requires employers to provide a workplace free from recognized hazards that are causing or likely to cause death or serious physical harm.
Question 3: Which of the following best describes 'condition-based maintenance'?
- Maintaining equipment according to operator preference
- Triggering maintenance actions based on measured performance indicators (Correct answer)
- Performing maintenance based on elapsed calendar time
- Replacing all parts on a fixed annual schedule
Correct answer: Triggering maintenance actions based on measured performance indicators
Condition-based maintenance uses real-time monitoring data—such as temperature, vibration, or oil analysis—to determine when maintenance is actually needed.
Question 4: What is the function of a 'bill of materials' (BOM) in manufacturing?
- To track the total labor hours spent on a production order
- To list all quality defects found during inspection
- To document machine preventive maintenance intervals
- To itemize all components, subassemblies, and raw materials required to build a product (Correct answer)
Correct answer: To itemize all components, subassemblies, and raw materials required to build a product
A BOM is a hierarchical list of all parts, subassemblies, and raw materials — with quantities — required to manufacture a finished product.
Question 5: What is a 'zero-defect' mindset in maintenance awareness?
- Accepting a small percentage of defects as normal
- Eliminating all maintenance records
- Reducing the maintenance workforce to zero
- Striving to prevent defects through proper equipment care and inspection (Correct answer)
Correct answer: Striving to prevent defects through proper equipment care and inspection
A zero-defect mindset drives operators and maintainers to prevent defects at the source rather than catching them after they occur.
Question 6: The concept of 'psychological safety' in a production team means:
- Team members feel safe to speak up, ask questions, and report concerns without fear of retaliation (Correct answer)
- Only supervisors are allowed to raise safety concerns
- Workers are not required to follow safety protocols

Correct answer: Performing the same motion repeatedly with little variation throughout a shift
Repetition is a primary ergonomic risk factor for musculoskeletal disorders (MSDs); performing the same motion repeatedly fatigues tissues and leads to injury over time.
Question 8: An operator measures 10 samples and calculates the standard deviation to be 0.05 mm. If the specification tolerance is 0.50 mm, what does this suggest about process capability?
- The process likely has good capability since the spread is much smaller than the tolerance (Correct answer)
- No conclusion can be drawn without knowing the process mean
- The process requires a Cpk study before any conclusion is possible
- The process is incapable because the standard deviation exceeds the tolerance
Correct answer: The process likely has good capability since the spread is much smaller than the tolerance
A standard deviation of 0.05 mm against a 0.50 mm tolerance (ratio of 1:10) strongly suggests the process has good spread capability relative to the specification.
Question 9: A production technician is measuring a bore diameter with a bore gage. The bore gage must first be set using a ring gage master. This process of setting the gage to a known value is called:
- Attribute inspection
- Verification
- Zeroing or mastering the gage (Correct answer)
- Gage R&R
Correct answer: Zeroing or mastering the gage
Mastering (zeroing) a gage means setting it to a known reference value so subsequent readings are relative to that standard.
Question 10: According to OSHA, what is the minimum distance that electrical equipment operating at 50–300 volts requires as a limited approach boundary for unqualified persons?
- 10 feet (3.05 m)
- No restriction unless voltage exceeds 300 V
- 3 feet 6 inches (1.07 m)
- Restricted to a distance set by the qualified worker; unqualified persons must not cross without escort (Correct answer)
Correct answer: Restricted to a distance set by the qualified worker; unqualified persons must not cross without escort
NFPA 70E and OSHA electrical safety standards require unqualified persons to remain outside the limited approach boundary, which is determined by the qualified worker based on voltage and conditions.
