What is the first step in the basic principles of first aid?

The correct first step in the basic principles of first aid is to assess for danger. This foundational step involves ensuring the safety of both the rescuer and the victim before any assistance can be provided. By checking for danger, a person performing first aid can identify any potential hazards in the environment, such as traffic, fire, or faulty electrical equipment, which could worsen the situation. Once the area is deemed safe, the rescuer can then proceed to assess the victim's condition and administer appropriate care.

Recognizing the environment before taking action is essential in first aid, as it minimizes the risk of further injury. Only after confirming safety should a responder evaluate the victim’s response, send for help if necessary, or check for airways and breathing, ensuring that actions taken are informed and deliberate.
