CHST Incident Investigation and Reporting 5

Question 1

Which element of the incident causation model represents conditions that allow or fail to prevent an unsafe act?

Accepted Answer

Precondition or enabling factor

Answer

Preconditions or enabling factors (sometimes called indirect causes) are environmental, organizational, or individual conditions that set the stage for unsafe acts to occur.

Question 2

A construction crew foreman witnesses a near-miss and decides not to report it to avoid paperwork. What systemic problem does this MOST likely reflect?

Accepted Answer

A punitive or blame-focused safety culture

Answer

Failure to report near-misses is a classic symptom of a punitive safety culture where workers fear reprisal; a just culture encourages reporting without blame.

Question 3

In a fault tree analysis (FTA) of a scaffold collapse, an AND gate means that:

Accepted Answer

All linked events must occur simultaneously for the outcome to result

Answer

An AND gate in FTA indicates that the output event occurs only when ALL of the input events occur simultaneously, making it useful for identifying compound failure modes.

Question 4

Which of the following BEST describes a 'contributing cause' in incident investigation terminology?

Accepted Answer

A condition that alone would not cause the incident but increased its likelihood or severity

Answer

Contributing causes are factors that increase the probability or severity of an incident but are insufficient on their own to cause it without the presence of other causes.

Question 5

An OSHA 301 Incident Report form must be completed within how many calendar days of a recordable work-related injury or illness?

Accepted Answer

7 calendar days

Answer

29 CFR 1904.29 requires employers to complete the OSHA 301 (or an equivalent form) within 7 calendar days of receiving information that a recordable case occurred.
