Step-by-Step Guide to Cleaning Up Blood Spills

Regardless of whether you choose cloth or paper towels, the following steps are crucial for safe and effective blood spill cleanup:

1. Personal Protective Equipment (PPE)

Before approaching any blood spill, put on personal protective equipment (PPE) to protect yourself from potential infection. Essential PPE includes:

• Gloves: Wear disposable gloves made of latex, nitrile, or vinyl to prevent direct contact with blood.
• Eye Protection: Safety glasses or a face shield protect your eyes from splashes.
• Mask: A face mask can prevent inhalation of airborne particles if the spill involves a large amount of blood or if aerosolization is likely (e.g., during forceful cleaning).
• Apron or Gown: A disposable apron or gown can protect your clothing from contamination.

2. Contain the Spill

To prevent the spill from spreading, contain the area using absorbent materials such as paper towels or cloth. Start from the outer edges of the spill and work your way inward. This will help to prevent the blood from spreading to other surfaces.

3. Absorb the Blood

Using your chosen material (paper towels or cloth), gently blot the blood spill. Avoid wiping, as this can spread the contamination. If using paper towels, use multiple sheets as needed and dispose of them immediately after use. If using cloth, use a clean section for each blot to avoid reintroducing blood to the surface.

4. Cleaning the Surface

After removing the bulk of the blood, the surface must be thoroughly cleaned and disinfected.

• Prepare a Disinfectant Solution: The Centers for Disease Control and Prevention (CDC) recommends using a solution of 1 part household bleach to 9 parts water (1:10 dilution) as an effective disinfectant for blood spills. Always prepare the solution fresh, as bleach degrades over time.
• Apply the Disinfectant: Using a clean cloth or paper towel, apply the disinfectant solution to the affected area. Ensure the entire surface is saturated.
• Contact Time: Allow the disinfectant to remain on the surface for at least 10 minutes. This contact time is crucial for killing pathogens.
• Wipe Clean: After the contact time, wipe the surface clean with a fresh, damp cloth or paper towel.
• Dry the Surface: Allow the surface to air dry or use a clean, dry cloth to dry it.

5. Proper Disposal of Contaminated Materials

Proper disposal of contaminated materials is critical to prevent the spread of infection.

• Place all contaminated materials (gloves, paper towels, cloth, PPE) in a biohazard bag or a sturdy plastic bag.
• Seal the bag tightly to prevent leakage.
• Label the bag as "Biohazard" or "Infectious Waste."
• Dispose of the bag according to local regulations for medical waste. In many areas, this may involve taking the bag to a designated medical waste disposal facility. If local regulations permit, you may be able to dispose of the bag in your regular trash, but be sure to check the specific guidelines in your area.

6. Cleaning and Disinfecting Cloth (If Used)

If you used cloth for the cleanup, it must be thoroughly cleaned and disinfected.

• Rinse: Rinse the cloth under cold running water to remove as much blood as possible.
• Wash: Wash the cloth in a washing machine with hot water (at least 160°F or 71°C) and a strong detergent.
• Disinfect: Add bleach to the wash cycle, following the manufacturer's instructions.
• Dry: Dry the cloth in a hot dryer.
• Alternative Disinfection Method: If a washing machine is not available, soak the cloth in a 1:10 bleach solution for at least 30 minutes, then rinse thoroughly and allow to air dry.

7. Hand Hygiene

After disposing of the contaminated materials and cleaning the area, it is essential to practice thorough hand hygiene.

• Remove gloves carefully to avoid contaminating your hands.
• Wash your hands with soap and water for at least 20 seconds. Ensure you scrub all surfaces of your hands, including between your fingers and under your nails.
• If soap and water are not available, use an alcohol-based hand sanitizer with at least 60% alcohol.
