Risk Assessment & Mitigation Flashcards

A fleet technician notices a vehicle's brake fade during a post-route inspection. Which mitigation action is MOST appropriate?

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.

Which risk matrix element represents the combination of likelihood and severity?

Answer: Risk score

A risk score (or risk rating) is calculated by multiplying or combining the likelihood of an event with its potential severity.

When conducting a Job Hazard Analysis (JHA) for a lift inspection task, the FIRST step is to:

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.

A fleet manager wants to reduce the frequency of tire blowouts. Which proactive mitigation measure is MOST effective?

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.

In fleet risk management, 'residual risk' is best defined as:

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.

A technician is about to perform a fuel system repair. Which hazard control represents the highest level in the hierarchy of controls?

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.

Which metric is MOST useful for trending vehicle-related risk in a fleet safety program?

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.
