What is the first action that should be taken after an injury occurs on site?

In the event of an injury occurring on site, providing first aid is the foremost action because it directly addresses the immediate needs of the injured individual. The priority is always the health and safety of personnel, and administering first aid can help stabilize the victim's condition while professional medical help is on the way. This action can prevent the situation from worsening and can be critical in saving lives or reducing complications.

While notifying a supervisor, documenting the incident, and evacuating the area are all important steps that follow an injury, they do not take precedence over ensuring the injured person receives care. First aid is a necessary response to injury management and should happen as swiftly as possible to ensure the best outcome for the injured party.
