3 C’s of Basic First Aid: Check, Call, Care

What are the 3 C’s in basic first aid?

The “3 C’s” in basic first aid are a simple way to remember what to do first in an emergency: Check, Call, and Care. This quick sequence helps you stay focused, protect yourself, and get the injured or ill person the right help as fast as possible.

How do the 3 C’s work in real life?

1) Check

Look for dangers before stepping in (traffic, fire, electrical hazards, violent behavior), then check the person for responsiveness and obvious life-threatening problems such as severe bleeding or trouble breathing. If it isn’t safe, keep your distance and wait for professionals.

2) Call

Call 911 (or your local emergency number) as soon as you suspect a serious issue, and give clear details: location, what happened, how many people are hurt, and what you see (unconsciousness, heavy bleeding, chest pain, seizure, etc.). If others are nearby, assign someone to call while you continue checking.

3) Care

Provide appropriate care until help arrives, based on your training and what you observe. That may include applying direct pressure to control bleeding, placing someone in the recovery position if they’re breathing but unresponsive, or starting CPR/AED use if they’re not breathing normally. Keep the person warm, calm, and as still as possible—especially with suspected head, neck, or back injuries.

When should you move beyond the 3 C’s?

The 3 C’s are the starting point, not the whole plan. If the situation is immediately life-threatening, you may need to act quickly after checking safety—such as calling 911 right away and beginning lifesaving steps.
