Incident Investigation Tips
OSHA strongly encourages employers to investigate every incident in which a worker is injured, as well as all close calls—or “near misses”—where an injury could have occurred if circumstances had been only slightly different.
In the past, the word accident was commonly used to describe an unplanned or undesired event. However, many people interpret “accident” as something random and unavoidable. Because nearly all workplace fatalities, injuries, and illnesses can in fact be prevented, OSHA recommends using the term incident investigation instead. Click here for Incident Investigation Course
Investigating a Worksite Incident:
Investigating any worksite incident—whether a fatality, injury, illness, or near miss—gives employers and employees the chance to identify hazards and weaknesses in their safety and health programs. Most importantly, it allows them to put meaningful corrective actions in place to prevent similar incidents in the future.
Incident investigations that focus on identifying and fixing root causes—rather than placing blame—help build morale and improve productivity by reinforcing the employer’s commitment to a safe and healthy workplace.
While supervisors often lead incident investigations, the most effective approach involves managers and employees working together. Each group brings different knowledge, experience, and perspectives that contribute to a more thorough investigation.
During an investigation, the team must look beyond immediate or surface-level causes. It is often too easy—and inaccurate—to conclude that an incident occurred simply because someone was careless or failed to follow a procedure. Such conclusions overlook deeper, root causes and make it impossible to identify the systemic changes needed to prevent recurrence. When a deficiency is found, it is important to ask why it existed and why it had not been addressed earlier.
If a procedure or safety rule wasn’t followed, why not?
Did production pressures influence the situation? If so, why were they allowed to outweigh safety considerations?
Was the procedure outdated, or was training inadequate? If so, why had these issues not been identified or corrected?
These examples show the importance of identifying all contributing factors—often involving equipment, procedures, training, or other safety program shortcomings.
Addressing underlying root causes is essential for truly understanding why an incident occurred, implementing effective corrective actions, and reducing or eliminating the likelihood of similar serious incidents in the future.
