Which of the following should be done in order to prevent the accident from happening again? Direct cause analysis Indirect cause analysis Root cause analysis

To prevent an accident from happening again, the most effective approach is **Root Cause Analysis (RCA)**. This method focuses on identifying the fundamental underlying issues that led to the accident, rather than just addressing the immediate or surface-level causes. By understanding and addressing the root causes, organizations can implement changes that effectively prevent similar incidents in the future. While direct cause analysis and indirect cause analysis can provide valuable insights, they may not fully address the deeper issues that need to be resolved to ensure long-term safety and prevention. Therefore, root cause analysis is the preferred method for preventing recurrence of accidents.
