CPP Risk Assessment & Management 2 — Questions and Answers
Question 1: A packaging engineer uses a Failure Mode and Effects Analysis (FMEA). What does the Risk Priority Number (RPN) represent?
- Sum of severity, occurrence, and detectability scores
- Product of severity, occurrence, and detectability scores (Correct answer)
- Ratio of severity to detectability
- Weighted average of all risk factors
Correct answer: Product of severity, occurrence, and detectability scores
RPN is calculated by multiplying Severity × Occurrence × Detectability, producing a number used to prioritize failure modes.
Question 2: Which regulatory body in the U.S. primarily governs packaging risk for food contact materials?
- OSHA
- EPA
- FDA (Correct answer)
- CPSC
Correct answer: FDA
The FDA regulates food contact substances, including packaging materials, under 21 CFR to ensure they do not pose health risks.
Question 3: A company ships lithium batteries in packaging that fails UN38.3 testing. What is the primary risk consequence?
- Increased freight costs
- Thermal runaway and fire during transport (Correct answer)
- Labeling non-compliance fines only
- Product obsolescence
Correct answer: Thermal runaway and fire during transport
Lithium batteries that fail UN38.3 testing are at risk of thermal runaway, which can cause fires or explosions during transport.
Question 4: During a packaging risk review, a product's fragility factor is determined to be 40G. Which packaging design strategy is most appropriate?
- Rigid outer container with no cushioning
- Minimal packaging to reduce weight
- Cushioning system designed to limit transmitted acceleration to below 40G (Correct answer)
- Double-wall corrugated box only
Correct answer: Cushioning system designed to limit transmitted acceleration to below 40G
Fragility factor (Gc) defines the maximum acceleration a product can withstand, so cushioning must be designed to keep transmitted G-forces below that threshold.
Question 5: What does a quantitative risk assessment provide that a qualitative assessment does not?
- Identification of hazards
- Numerical probability and impact values for risks (Correct answer)
- Stakeholder communication templates
- Regulatory compliance documentation
Correct answer: Numerical probability and impact values for risks
Quantitative risk assessment assigns numerical values to probability and consequences, enabling prioritization and cost-benefit analysis beyond what qualitative ratings provide.
Question 6: A packaging line experiences recurring seal failures on pouches. In a risk management context, what is the most effective first step?
- Replace all equipment immediately
- Conduct root cause analysis to identify the failure mechanism (Correct answer)
- Add a warning label to the product
- Increase inspection frequency only
Correct answer: Conduct root cause analysis to identify the failure mechanism
Root cause analysis identifies the underlying mechanism of failure, enabling targeted corrective actions rather than symptomatic fixes.
Question 7: Which distribution environment hazard is typically assessed using ASTM D4169 simulation protocols?
- Chemical migration from packaging
- Vibration, shock, compression, and climate stresses during transit (Correct answer)
- Consumer misuse of packaging
- Regulatory labeling compliance
Correct answer: Vibration, shock, compression, and climate stresses during transit
ASTM D4169 provides standardized test sequences simulating distribution hazards including vibration, drop, compression, and temperature/humidity exposure.
