Biohazard cleanup refers to the process of cleaning up and removing potentially hazardous materials, such as blood, body fluids, and chemicals, from a trauma scene or other contaminated area to prevent the spread of diseases and ensure the safety of everyone involved. If you want to know more about biohazard cleanup, then this article is for you. 

Here’s what you need to know about biohazard cleanup and how it is done:

Biohazard Cleanup: 

Biohazard cleanup is the disinfection, sanitizing, and deodorizing of places where a trauma incident occurred such as injury, accident, or death. Such areas often contain blood, human or animal residues, chemical spills, etc.

Types of Biohazards

Biological hazards can include human blood, vomit, other bodily fluids, tissues that contain blood, animal waste, materials typically bedding that is known to be infected, animal corpses or body parts, pathological waste, microbiological waste, and sharps waste.


Proper handling of the crime or trauma scene is crucial to the safety of everyone involved. Biohazard cleanup can be challenging work that requires technicians to handle potentially hazardous materials such as blood and body fluids, and it is best left to professionals.


The biohazard cleanup process involves several steps, including:

  • Evaluation: Assess the extent of the contamination and determine the appropriate cleaning methods and equipment required.
  • Containment: Set up barriers and isolation zones to prevent the spread of contamination.
  • Cleaning: Clean and disinfect all surfaces, objects, and materials that may have been contaminated using appropriate cleaning agents and tools.
  • Disposal: Dispose of all contaminated waste, including biohazardous materials, in compliance with local and state regulations.
  • Verification: Conduct post-cleanup testing to ensure that the area is free of contamination and safe for occupancy.
  • Cost: The cost of biohazard cleanup can vary depending on the extent of the contamination and the specific services required. A low-cost cleanup will be somewhere between $1,500 and $2,500.

Why Biohazard Clean-up is Important?

  1. Biohazard clean-up is essential for ensuring that environments affected by biohazardous materials no longer pose a threat to human health. Biohazard cleaning involves the removal of biohazard materials and the disinfection of affected areas.
  2. Biohazardous materials can include bodily fluids, animal remains, and chemical spills. In many cases, biohazard cleaning services are required after traumatic events such as homicides, suicides, and accidents. Biohazard cleaning services can also include cleaning up after a mouse infestation in a residence.
  3. Biohazard clean-up is critical for preventing the spread of infectious diseases, protecting the safety of first responders and other individuals who may come into contact with the affected area, and reducing the risk of liability for property owners and businesses. Proper biohazard clean-up involves thorough disinfection of surfaces and the safe removal of any unsalvageable materials from the area.
  4. It is important to ensure that biohazard clean-up is carried out in accordance with safe systems of work and site-specific risk assessments and method statements. In addition, proper disposal of biohazardous materials is crucial to prevent contamination of the environment and protect public health.

Overall, it is important to hire trained professionals to carry out biohazard clean-up services and to follow proper safety protocols to minimize the risk of exposure to biohazardous materials.

Tips to Clean Biohazardous Material

Cleaning biohazardous material can be a dangerous task that requires careful handling and proper disposal to prevent the spread of infection or disease. Here are some tips to clean biohazard material:

  • Minimize contact with the biohazardous substance and get it into a sealable container as fast as possible.
  • Make sure your containers are sturdy and puncture-resistant to reduce the risk of the container breaking and releasing an infection or disease.
  • Separate non-disposable biohazardous materials and transport them safely.
  • Wear personal protective equipment to protect your eyes, nose, mouth, and skin. Goggles, an N-95 respirator, and protective gloves are recommended.
  • Mix 1 cup of household bleach with 1 gallon of water to make a cleaner for biohazard material. However, do not use bleach in a closed space, and ensure that windows and doors are open before use.
  • Identify the type of biohazardous waste you are handling to ensure proper disposal. The 4 main categories of biohazardous waste are solid biohazardous waste, liquid biohazardous waste, sharps biohazardous waste, and pathological biohazardous waste.
  • If you are unsure about how to handle a particular spill, immediately call the Medical Campus Control Center or the CRC EHS emergency.
  • Disinfect the spill area with a 10% bleach solution or other approved disinfectant. Allow thirty minutes for the disinfectant to sit on the spill and stain before cleaning it up with paper towels.
  • Biohazard waste is typically treated in an autoclave process which renders the waste harmless and then it is disposed of.

It is important to follow proper procedures for cleaning biohazardous material to protect yourself and others from the risk of infection or disease. If you are unsure about how to handle a particular situation, seek professional help immediately.


Biohazard cleanup is a crucial process that involves the safe removal and disposal of potentially hazardous materials from contaminated areas to prevent the spread of diseases and ensure the safety of everyone involved. It is best left to professionals who have the training, experience, and equipment required to perform the task safely and effectively.
