The best overall approach is to treat every person as potentially infectious and consistently use barriers and hygiene so germs never reach your skin, mouth, eyes, or an open wound.

Core Principle: Standard Precautions

Standard precautions mean you protect yourself the same way every time, no matter who the casualty is or what they look like.

Key ideas:

  • Assume blood and body fluids can carry infection.
  • Use barriers (gloves, mask, eye protection) whenever fluids might be present.
  • Clean hands before and after care, even if you wore gloves.

Most Important Step: Hand Hygiene

Proper hand hygiene is widely regarded as the single most important measure to prevent infection during first aid.

Do:

  • Wash hands with soap and water for at least 20 seconds before and after providing care.
  • Use alcohol-based hand rub (at least 60% alcohol) if soap and water are not available.
  • Avoid touching your face, eyes, nose, or mouth while giving care.

Practical Steps While Giving First Aid

When you step in to help, follow this simple sequence to lower risk of infection.

  1. Before you touch the person
    • Perform hand hygiene (wash or use sanitizer).
 * Put on disposable gloves if there is any chance of contact with blood, vomit, saliva, or other body fluids.

 * Add a mask and eye protection if splashes are possible (severe bleeding, coughing, CPR with risk of fluids).
  1. While treating wounds or illness
    • Avoid direct contact with blood and body fluids; use gauze, dressings, and tools instead of bare hands.
 * Clean wounds gently with clean water or saline; remove dirt before dressing.

 * Use clean or sterile dressings and bandages; do not reuse materials.

 * Do not cough or sneeze over wounds; turn away or into your elbow if you must cough.
  1. After care is given
    • Carefully remove gloves without touching the outside surface, and dispose of them and any contaminated materials in a proper waste bag/container.
 * Wash hands again thoroughly.

 * Clean and disinfect any surfaces or equipment contaminated with blood or body fluids (for example, a table, scissors, or first-aid box).

Extra Protective Measures

These steps add another layer of safety, especially if you give first aid often.

  • Keep vaccinations (like tetanus and hepatitis B) up to date if you’re a regular responder.
  • Store a well-stocked first aid kit with:
    • Gloves, face shields/CPR masks, eye protection.
    • Sterile dressings, gauze, bandages.
    • Alcohol hand rub, antiseptic wipes.
  • Disinfect reusable equipment (like scissors or blood pressure cuffs) after use according to guidance.

Simple One-Sentence Takeaway

Use proper hand hygiene and appropriate protective barriers (especially gloves) every time you give first aid, and clean up safely afterward to greatly reduce the risk of infection.
