What must be done if someone is injured on the job site?

Administering first aid and immediately reporting the incident is the appropriate response when someone is injured on the job site. Taking prompt action can significantly impact the injured person's recovery and safety. Administering first aid ensures that any immediate medical needs are addressed, which may help prevent further injury or complications.

Reporting the incident immediately is crucial as it allows for appropriate medical assistance to be summoned and enables the management to begin an investigation into the circumstances surrounding the injury. This can help identify any safety issues or hazardous conditions that may need to be addressed to prevent future incidents.

Timely action in these scenarios is paramount for maintaining a safe work environment and ensuring compliance with safety protocols and regulations. The other options do not prioritize the injured person's well-being or violate standard safety procedures.
