Evaluate employee performance
Identify and control hazards associated with specific job tasks before work begins (Correct answer)
Calculate worker compensation rates
Audit supplier safety programs

Correct answer: Identify and control hazards associated with specific job tasks before work begins

A JSA breaks a job into steps, identifies hazards at each step, and recommends controls to prevent injuries.

Question 15: What is 'capacity planning' in production management?

Determining the production capacity needed to meet demand over time (Correct answer)
Designing plant floor layouts
Scheduling employee vacations
Planning warehouse storage space

Correct answer: Determining the production capacity needed to meet demand over time

Have more than 50 employees
Operate more than one production shift
Use, store, or handle highly hazardous chemicals above threshold quantities (Correct answer)

Correct answer: Use, store, or handle highly hazardous chemicals above threshold quantities

PSM (29 CFR 1910.119) requires comprehensive safety programs for processes involving chemicals that pose catastrophic release risks.

Question 17: What does 3PL stand for?

Total Plant Layout
Third-Party Logistics (Correct answer)
Three-Phase Loading
Tiered Procurement Levels

Correct answer: Third-Party Logistics

Third-Party Logistics (3PL) refers to outsourcing logistics functions such as warehousing, transportation, and fulfillment to a specialized provider.

Question 18: In quality management, what is a 'specification limit'?

The acceptable boundary defined by engineering or the customer (Correct answer)
A statistical control boundary
The natural range of process variation
The machine's maximum operating range

Correct answer: The acceptable boundary defined by engineering or the customer

Specification limits (USL and LSL) define the acceptable range for a product characteristic as required by the customer or design.

Question 19: In manufacturing maintenance, what does a Pareto analysis help identify?

The 20% of failure causes responsible for 80% of downtime (Correct answer)
The optimal lubrication schedule for all machines
The sequence of preventive maintenance tasks

Correct answer: The 20% of failure causes responsible for 80% of downtime

Pareto analysis identifies the vital few causes (roughly 20%) that account for the majority (roughly 80%) of equipment failures or downtime, allowing teams to prioritize corrective actions.

Question 20: What is the recommended practice when a machine shows signs of overheating during production?

Reduce the production speed by 5% and monitor for improvement
Increase coolant flow and continue production to avoid downtime
Replace the cooling fan and restart immediately without further inspection
Shut down the machine and investigate the cause before resuming operation (Correct answer)

Correct answer: Shut down the machine and investigate the cause before resuming operation

Overheating is a warning sign of a developing problem; shutting down and investigating the cause prevents further damage, fire risk, and more costly repairs.

Question 21: An OSHA 'willful violation' is defined as one where:

The employer was unaware of the hazard
The violation was self-reported
The violation occurred after hours
The employer intentionally disregarded the law or showed plain indifference to worker safety (Correct answer)

Correct answer: The employer intentionally disregarded the law or showed plain indifference to worker safety

Willful violations carry the highest OSHA penalties and occur when an employer knowingly allows a hazardous condition to exist.
