Read the first 7 Accident Investigation and Analysis flashcards as text

  1. During an accident investigation interview, which technique best encourages a witness to provide a full, unfiltered account?

    Answer: Begin with open-ended questions and allow the witness to narrate without interruption

    Open-ended narrative questions reduce interviewer bias and allow witnesses to reveal details the investigator may not have anticipated.

  2. Fault Tree Analysis (FTA) is a technique that works:

    Answer: Top-down, starting from an undesired event to identify contributing causes

    FTA uses a top-down deductive approach, beginning with a defined undesired top event and tracing backward through logical gates to identify root causes.

  3. Which OSHA standard requires employers to record and report work-related fatalities, injuries, and illnesses?

    Answer: 29 CFR 1904

    29 CFR 1904 contains OSHA's recordkeeping requirements, including the 300 Log, 301 Incident Report, and 300A Annual Summary.

  4. In the context of accident investigation, 'perishable evidence' refers to:

    Answer: Physical or observational evidence that degrades, disappears, or changes rapidly if not collected immediately

    Perishable evidence such as skid marks, spilled fluids, environmental conditions, and witness memory degrades quickly and must be documented promptly.

  5. A supervisor who completes an incident investigation report and codes the cause only as 'employee carelessness' has most likely:

    Answer: Stopped the analysis too early and missed systemic causes

    Attributing accidents solely to worker carelessness is a surface-level conclusion that ignores systemic failures in training, design, supervision, or procedures.

  6. The Management Oversight and Risk Tree (MORT) analysis tool is primarily used to:

    Answer: Identify management system deficiencies and oversights that contribute to accidents

    MORT is a comprehensive analytical logic tree used to identify both specific control failures and management system weaknesses that allowed an accident to occur.

  7. When determining the 'scope' of an accident investigation, the safety supervisor should consider:

    Answer: The severity of the injury and potential severity, as well as recurrence probability

    Investigation scope and depth should be proportional to both the actual outcome and the worst potential outcome, as well as the likelihood of recurrence.
