Basic first aid in emergencies
How to respond to bleeding, fractures, and unconscious people while professional help arrives. Always call 911 first.
Before acting
- Call (or have someone call) 911 before starting to help.
- Make sure the area is safe for you: do not become another victim.
- Do not move a seriously injured person unless they are in immediate danger (fire, collapse).
Bleeding
- Press directly on the wound with a clean cloth, without letting go, for at least 10 minutes.
- If the cloth soaks through, do not remove it: add another on top and keep pressing.
- Raise the injured limb above the heart if there is no fracture.
- Only use a tourniquet if bleeding is massive and does not stop with pressure: note the time you applied it.
Unconscious person
- Check for breathing: watch the chest for 10 seconds.
- If they are breathing, place them on their side (recovery position) and watch them until help arrives.
- If they are not breathing, start compressions in the center of the chest: hard and fast, about 100–120 per minute, without stopping until help arrives or the person responds.
Never give liquids to an unconscious or semi-conscious person. They can choke.
Fractures and trauma
- Do not try to straighten a deformed limb.
- Immobilize the area with what you have (boards, rolled magazines, cloth) without squeezing too hard.
- Apply local cold (never ice directly on skin) for pain and swelling.
- If you suspect a neck or back injury, do not move the person and wait for rescuers.
People trapped in rubble
- Do not move large debris on your own: it can collapse onto the victim or onto you.
- Mark the spot, talk to the person to keep them conscious, and alert rescuers (911 or 166).
- Rhythmic tapping on pipes or structures helps teams with listening equipment locate victims.
