NCT Risk Assessment & Mitigation 2 — Questions and Answers
Question 1: A fleet technician notices a vehicle's brake fade during a post-route inspection. Which mitigation action is MOST appropriate?
- Log the finding and schedule repair at next available slot
- Remove the vehicle from service immediately pending brake system inspection (Correct answer)
- Top off brake fluid and return the vehicle to service
- Advise the driver to avoid steep grades until the next PM cycle
Correct answer: Remove the vehicle from service immediately pending brake system inspection
Brake fade is a safety-critical finding that warrants immediate removal from service until a full brake system inspection is completed.
Question 2: Which risk matrix element represents the combination of likelihood and severity?
- Residual risk
- Inherent risk
- Risk score (Correct answer)
- Risk tolerance
Correct answer: Risk score
A risk score (or risk rating) is calculated by multiplying or combining the likelihood of an event with its potential severity.
Question 3: When conducting a Job Hazard Analysis (JHA) for a lift inspection task, the FIRST step is to:
- Identify the personal protective equipment required
- Break the job into discrete sequential steps (Correct answer)
- Determine corrective actions for each hazard
- Rank hazards by severity
Correct answer: Break the job into discrete sequential steps
A JHA begins by listing every discrete step in the job before hazards associated with each step can be identified.
Question 4: A fleet manager wants to reduce the frequency of tire blowouts. Which proactive mitigation measure is MOST effective?
- Increasing driver incident reporting thresholds
- Implementing a structured tire pressure monitoring and rotation schedule (Correct answer)
- Replacing tires only after a blowout occurs
- Posting speed limit reminders in vehicles
Correct answer: Implementing a structured tire pressure monitoring and rotation schedule
Structured tire pressure monitoring and scheduled rotations directly address the leading causes of blowouts before they occur.
Question 5: In fleet risk management, 'residual risk' is best defined as:
- Risk that remains after all feasible controls have been applied (Correct answer)
- The total unmitigated risk before any controls are in place
- Risk transferred to a third-party insurer
- Risk associated with legacy vehicle models
Correct answer: Risk that remains after all feasible controls have been applied
Residual risk is what remains after mitigation controls have been implemented and is the level of risk accepted by management.
Question 6: A technician is about to perform a fuel system repair. Which hazard control represents the highest level in the hierarchy of controls?
- Wearing flame-resistant PPE
- Using a fire extinguisher nearby
- Eliminating ignition sources from the work area (Correct answer)
- Posting flammable-materials warning signs
Correct answer: Eliminating ignition sources from the work area
Elimination of the hazard (removing ignition sources) sits at the top of the hierarchy of controls, above engineering and administrative controls.
Question 7: Which metric is MOST useful for trending vehicle-related risk in a fleet safety program?
- Total fuel expenditure per vehicle
- Miles per gallon average
- Preventable accident rate per million miles (Correct answer)
- Average vehicle age
Correct answer: Preventable accident rate per million miles
Preventable accident rate per million miles normalizes incident data for fleet size and exposure, making it the standard risk-trending metric.
