CSS Accident Investigation and Analysis 3

Question 1

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

Accepted Answer

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

Answer

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

Question 2

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

Accepted Answer

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

Answer

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

Question 3

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

Accepted Answer

29 CFR 1904

Answer

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

Question 4

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

Accepted Answer

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

Answer

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

Question 5

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

Accepted Answer

Stopped the analysis too early and missed systemic causes

Answer

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