What to Expect During a Biohazard Cleanup: FAQs for Chicagoland Property Owners

Discovering a biohazard on your property is a deeply unsettling experience. 

Whether it’s the aftermath of a crime, a tragic accident, an unattended death, severe hoarding, or a devastating sewage overflow, these situations present not only a physical mess but also a significant emotional burden. 

When facing such an event in your Chicagoland home or business, understanding what to expect can provide a much-needed sense of control. Let’s answer your most common questions about biohazard cleanup, including why choosing an experienced, compassionate local team matters.

What Is Biohazard Cleanup?

A biohazard is any hazardous material that may pose a threat to human or animal health.

Biohazard cleanup is the professional removal, cleaning, and disinfection of contaminants such as bodily excretions, animal waste, chemicals, or other infectious agents from your property. 

This process restores the affected area to a safe, habitable condition and ensures any risks are eliminated.

From pathogens found in blood and bodily fluids to dangerous bacteria in raw sewage, these substances require specialized handling and decontamination to prevent illness and further contamination. 

Common biohazard scenarios we address include:

• Crime scenes: This often involves blood, bodily fluids, and other unpleasant materials resulting from violent acts.
• Death aftermath: Unattended deaths and decomposition can create significant biohazards and odors.
• Accidents: Workplace or residential accidents involving serious injuries can leave behind blood and potentially infectious debris.
• Sewage cleanup: Overflows from clogged pipes or natural disasters can flood properties with raw sewage that carries dangerous bacteria and viruses.
• Hoarding situations: Extreme hoarding can lead to the accumulation of animal waste, human waste, mold, and unsanitary conditions.

The invisible threats posed by pathogens present in biohazards mean that what seems like a simple mess could harbor serious health risks for you and your family. That’s why professional intervention is crucial.

What Happens During a Biohazard Cleanup?

Attempting to clean up biohazards yourself is not the best idea. Bloodborne pathogens, bacteria, and toxic chemicals can linger on surfaces and in the air, posing serious health threats even after visible contaminants are removed.

Proper biohazard remediation requires specialized training, equipment, and adherence to OSHA, EPA, and state health regulations.

In 2021, the Trauma Scene Waste Management Registration Act was introduced to the Illinois General Assembly. The bill required the registration of trauma scene waste management practitioners. Illinois Administrative Code title 77, § 265.2050 outlines how the disposal of pathological and bacteriological waste must be permitted by the Illinois EPA.

The Biohazard Cleanup Process: Step-by-Step

Every situation is unique, but most biohazard cleanups follow these core steps:

1. Assessment and Planning

A certified team conducts a thorough assessment, identifying all affected areas and potential hazards. This step ensures a tailored cleanup plan that meets local health regulations while restoring the property as quickly as possible.

2. Containment and Safety Preparation

Technicians set up physical barriers and wear personal protective equipment (PPE) such as gloves, suits, masks, and goggles to prevent cross-contamination and protect themselves and others.

3. Removal of Hazardous Materials

All visible biohazardous matter — blood, fluids, contaminated materials, debris, and waste — is carefully removed. Porous items beyond cleaning (like carpets or mattresses) are disposed of as regulated medical waste.

4. Cleaning and Disinfection

Surfaces are cleaned with hospital-grade disinfectants to remove any remaining contaminants. This step is repeated as needed to ensure thorough sanitation.

5. Deodorization

Odors from decomposition, sewage, or chemicals are neutralized using specialized equipment, ensuring your residence or business is not only clean but also comfortable to re-enter.

6. Verification and Clearance

Technicians perform tests, such as ATP (adenosine triphosphate) swabs, to confirm that all biohazards have been eliminated. Only after passing strict safety standards is the area declared safe for your use again.
