Materials
- Clean cloth
- Improvised bandage
- Tourniquet—a manufactured one if available; improvised only as a last resort
Steps
- 1Expose the wound and press hard directly on it with a dressing or clean cloth.
- 2For a deep wound, pack the cloth firmly into it, then keep pressing on top; do not peek repeatedly.
- 3For life-threatening bleeding from an arm or leg, apply a tourniquet straight away if you have one: 5–7 cm above the wound, not over a joint, tightened until the bleeding stops. Note the time and never loosen it.
- 4Keep the person lying down, warm and calm while you call for help.

Common mistakes
- Removing pressure to “check” too often
- Tourniquet used casually for minor bleeds
- Ignoring shock
