Who is this programme for?
Supervisors, safety officers and managers who collect incident information and recommend actions to prevent recurrence.
What will you learn?
Use evidence to explain what happened, why it happened and what changes can prevent a repeat.
- Gathering records, observations and interview evidence without jumping to conclusions.
- Separating immediate events from underlying organisational causes.
- Writing findings, assigning corrective actions and checking their effectiveness.
How can an investigation lead to better prevention?
A sound investigation builds a sequence from evidence rather than starting with a preferred explanation. Different accounts, records and physical observations may reveal gaps between the planned task and what happened. Understanding those gaps helps identify whether equipment, planning, training or supervision needs improvement.
The final report should make the connection between causes and actions clear. A recommendation is more useful when it addresses the underlying weakness and can be checked for effectiveness after implementation.
How is the published knowledge assessment structured?
The OSHAS programme page describes an open-book knowledge assessment with 2 hours allowed and a minimum pass score of 65%. These are the rules for this programme, not a universal pass mark for every OSHAS course. Practical duties also require competence appropriate to the work.
Why investigate a near miss when nobody was injured?
A near miss can reveal failed controls before the same conditions cause harm. Examining the sequence of events helps identify weaknesses in planning, equipment, communication or supervision. The aim is useful prevention, rather than stopping the enquiry at a label such as carelessness.
