What Are You Legally Required to Do Before You Touch a Person When Responding to an Emergency?

The answer

Before you physically touch someone during an emergency, the law requires you to obtain the person's consent. Touching a person without permission can technically be considered battery, so consent is the legal gateway to giving care. How you get that consent depends on the victim's condition:

• Conscious, competent adult → you must obtain expressed consent (also called actual or informed consent).
• Unconscious, unresponsive, confused, or otherwise unable to answer → the law recognizes implied consent, allowing you to act.

The standard way to get expressed consent is to identify yourself, state your level of training, and ask permission—for example: "Hi, my name is Alex, I'm trained in first aid. May I help you?" If the person says yes, you may proceed. If a competent adult says no, you must respect that refusal.

Expressed vs. implied consent

This distinction is the heart of the exam question and the piece most study pages gloss over.

Expressed consent is direct permission—spoken, nodded, or gestured—given by a conscious person who understands the situation. To be valid, the person must be a competent adult (of sound mind, not severely impaired). You should tell them who you are, your training, and what you intend to do, then wait for a "yes."

Implied consent applies when a reasonable person would agree to care but cannot express it. This covers:

• An unconscious or unresponsive victim.
• Someone so injured, confused, or intoxicated that they cannot make a rational decision.
• A minor whose parent or guardian is not present to consent on their behalf.

The law assumes that any reasonable person in a life-threatening situation would want help, so silence or unresponsiveness is treated as a "yes."

Why consent connects to Good Samaritan protection

Getting consent is not just etiquette—it is what keeps you protected. Good Samaritan laws shield rescuers who act voluntarily, in good faith, without gross negligence, and within the scope of their training from being sued for unintended harm. But those protections generally assume you acted properly—and acting properly starts with obtaining consent. If you touch a competent adult who has refused help, you may fall outside Good Samaritan protection and expose yourself to a battery claim.

So the correct sequence in almost every first-aid course is:

1. Check the scene for safety.
2. Obtain consent (expressed if conscious, implied if not).
3. Call 9-1-1 if needed.
4. Provide care within your training.

The bigger picture

Other common exam distractors—"call 9-1-1 first," "check for a pulse," or "put on gloves"—are all good practices, but the legal requirement before you lay hands on someone is consent. Remember the rule: ask before you act if they're awake; assume yes if they're not. That single principle satisfies both the legal requirement and the ethical one, and it keeps your Good Samaritan protection intact.
