A good investigation is likely to reveal several contributing factors.

• A. Elements that contribute to the incident but are not direct causes
• B. Direct causes
• C. Immediate triggers
• D. Safe practices

Answer: (A)

In an effective investigation, incidents are usually the result of multiple contributing factors within the system, not a single event. This means looking at a mix of conditions in people, processes, equipment, and the work environment that allowed the incident to occur. The option describing factors that contribute but are not direct causes best captures this broader view, since it acknowledges that several underlying conditions work together to produce an incident. Direct causes or immediate triggers explain what happened in the moment, but they don’t account for the collection of factors that set the stage. Safe practices are protective measures; their presence would reduce risk, not contribute to an incident. For example, a spill might be directly caused by a broken container, but contributing factors could include improper storage design, inadequate maintenance, and insufficient training on handling hazardous materials.
