Question 1

Which accident investigation method uses a top-down logic diagram with AND/OR gates to show combinations of failures that can lead to an undesired event?

Accepted Answer

Fault tree analysis

Answer

Fault tree analysis uses a deductive, top-down diagram with AND/OR logic gates to map all pathways of failures that can cause a specific undesired event.

Question 2

The Management Oversight and Risk Tree (MORT) analysis methodology was originally developed for use in which industry?

Accepted Answer

Nuclear energy

Answer

MORT was developed by the U.S. Atomic Energy Commission and later adapted for use across multiple industries, including mining.

Accepted Answer

Root causes by iteratively asking why each causal factor occurred

Answer

The 5 Whys method drills through successive causal layers by treating each answer as the subject of the next 'why' question until a root cause is reached.

Question 4

When investigators arrive at a mine accident scene, what should be the FIRST priority?

Accepted Answer

Preserve and document the scene before anything is disturbed

Answer

Scene preservation through photography, measurements, and detailed documentation must occur before any evidence is moved or conditions change.

Question 5

A 'near-miss' incident in mine safety is best defined as:

Accepted Answer

An unplanned event with injury potential that did not result in harm or property damage

Answer

Near-miss events reveal system weaknesses that could lead to serious injury and are valuable learning opportunities because no harm actually occurred.
