Biohazard –Virus Cleanup Procedure

Overview:

Cleaning biological viruses from a biohazard event requires stringent procedures to ensure safety and efficacy. This procedure outlines the necessary equipment, chemicals, and steps to effectively manage viral contamination, especially COVID. This procedure can apply to C-Diff, but should be discussed internally before proceeding.

Equipment Necessary:

  1. Personal Protective Equipment (PPE):

    • Nitrile Gloves: 6 mil

    • Respirator: Full-face.

    • Suits: White coveralls with long sleeve and foot protection.

  2. Cleaning Supplies:

    • Microfiber Cloths: For wiping surfaces.

    • Fogger: Backpack, 4-gallon capacity. 1-gallon Airofog acceptable.

  3. Chemicals Needed:

    • Disinfectant: (e.g., EPA-registered disinfectants effective against viruses) for cleaning surfaces. Chem Decon A, B, C.

Step-by-Step Procedure:

Preparation:

  1. Site Assessment:

    • Inspect the area for potential viral contamination and assess the extent of the contamination.

    • Cover with painters tape all smoke detection systems.

  2. ATP Test:

    • Three non-porous surfaces.

  1. Treatment:

    • Fogging with Chem Decon.

    • Wipe down high-touch surfaces with spray bottle of Chem Decon and hand-held microfiber cloths.

    • Wipe down floors with Unitex to eliminate slipperiness.

  2. ATP Testing:

    • Same sites as previously tested. RLU should show one to two or more orders of magnitude improvement. Any value under 20 RLUs is acceptable.

Post-Cleanup:

  1. Waste Disposal:

    • Dispose of all contaminated materials (e.g., gloves, cloths) in biohazard bags.

    • Follow local regulations for the disposal of biohazard waste.

  2. Post-Cleanup Inspection:

    • Inspect the area to ensure all surfaces have been treated.

  3. Hygiene Practices:

    • Wash hands thoroughly after removing PPE and completing the cleanup.

Conclusion:

This procedure outlines the steps necessary for safely cleaning biological viruses in a biohazard event. Proper equipment, PPE, and cleaning protocols are essential to ensure safety and effective management of viral contamination. Always prioritize training and adherence to procedures for optimal outcomes.
