What key data should an accident report contain?

An effective accident report is crucial because it helps identify the causes of an incident and guides future prevention measures. Including a comprehensive description of the accident provides context and details about what occurred, which is essential for understanding the circumstances. Additionally, documenting the number of people involved gives a clear picture of the accident's extent and potential impact on personnel.

Furthermore, noting any defective equipment or unsafe conditions that may have contributed to the accident is vital for assessing safety protocols and identifying areas for improvement. Collectively, all these elements contribute to a complete and informative report that can assist in making the workplace safer and preventing similar incidents in the future. Therefore, the answer that encompasses all these components is the most appropriate choice, as it reflects the necessary breadth of information required in an effective accident report.
