You reach an injured classmate who is bleeding. Before you touch the wound, what safety precaution comes first?

1. A safety precaution protects the helper from the casualty's body fluids. 2. Putting on protective gloves does that, and it must happen before any contact. 3. Washing your hands with soap belongs after administering first aid, not before. 4. Calling an ambulance is the last step, arranging further treatment once the casualty is stable. 5. Washing and drying the wound are first-aid procedures — treatment of the casualty rather than protection of the helper. _Source: NECTA CSEE 2021 Biology 033, Question 1: Multiple Choice, item (iii)_
