Step 1: Check for any danger / find out what has happened
You, the first aider, are always the most important person. Always check for danger to yourself before entering a situation. Find out how the injury has occurred and ensure an ambulance has been called.
Step 2: Apply direct pressure over the wound
Use any material available (e.g: pieces of clothing, towels, plastic bags etc.) to apply direct pressure over the wound. Do not release the pressure until further help arrives.
Special circumstance: If there is an object in the wound (for example, a piece of glass) then do not remove it. Instead, apply pressure around the edges of the wound to control the bleeding.
Step 3: If the person feels unwell, lie them down and elevate their legs
This will increase the blood supply to the brain. Also, try to keep the person warm.
