What should you do first when approaching an unresponsive person?

When approaching an unresponsive person, the first step is to tap them and shout "Are you OK?" This action is crucial because it helps to assess the person's level of responsiveness. By attempting to elicit a response verbally and through gentle physical contact, you can determine if the person is in fact unresponsive or if they may be in a state where they can still communicate or react.

If the person does not respond to your verbal cue or physical touch, it indicates a more serious condition, warranting immediate next steps. This includes calling for help or initiating emergency response protocols such as checking for breathing or performing CPR, depending on the situation.

Taking this initial step to communicate serves an important role in ensuring the safety of the unresponsive individual and allows you to act quickly based on their condition. Thus, tapping the person and shouting is the appropriate first action to confirm their state and decide on the ensuing measures.
