Within what time frame must the supervisor report be completed after an employee injury?

The correct timeframe for completing the supervisor report after an employee injury is 24 to 72 hours. This timeframe is established to ensure that the incident is documented while the details are still fresh in the minds of those involved, which can lead to more accurate reporting. Timely reporting is crucial for effective incident management, investigation, and follow-up actions, as it provides essential information for identifying the cause of the injury and preventing future occurrences. It can also play a significant role in the company's compliance with occupational safety regulations and workers' compensation requirements.

The other options don't align with standard practices and regulations, as they either set the timeframe too short or too lengthy to effectively manage and respond to workplace incidents.
