What is the difference between an 'immediate cause' and an 'underlying cause' of an accident?
-
A
They are the same — there is only one cause to identify
-
B
The immediate cause is the direct trigger of the accident (e.g., a worker slipped); underlying causes are the management, organisational, or system failures that allowed the condition to exist (e.g., no housekeeping policy)
-
C
The immediate cause is always the worker's fault; the underlying cause is always a management failure
-
D
Underlying causes are only relevant for fatal accidents
