Crime scene cleaning is the professional removal of biohazardous materials from a property after law enforcement completes its investigation. Through biohazard remediation, certified technicians handle blood, bodily fluids, and other dangerous contaminants that pose serious health risks to anyone who enters the space.
According to the FBI's 2024 Reported Crimes in the Nation statistics, a violent crime occurred, on average, every 25.9 seconds in the United States. Once investigators leave, hazardous wastes remain a significant danger. Blood and bodily fluids carry deadly pathogens that stay infectious for days.
Once the police clear the scene, remediation becomes your private responsibility. You have to partner with certified professionals who come in to contain and eradicate these health risks. If you're unsure what to do, our crime scene cleaning guide will show you the next steps to take.
What Does Biohazard Remediation Mean?
Biohazard remediation is the process of removing, cleaning, and disposing of biohazardous waste. You'll need remediation after:
- Homicides
- Assault scenes
- Attempted suicides
- Unattended deaths
- Industrial accidents
- Crimes involving methamphetamine labs
These situations often involve bodily fluids, toxic waste, or chemicals. If you don't handle the disposal properly, indoor environmental hazards can spread infections that negatively affect your health.
What Are the Types of Biohazards Present in a Crime Scene?
Biohazards will exist in crime scenes in different states, depending on the type of scene you have. You'll find blood and bodily fluids like saliva or sexual fluids in cases involving assault, accidents, or deaths. Body tissues and parts are also present in these cases.
Crime scenes in labs or medical clinics may contain microbiological waste and chemical contaminants such as drugs or industrial chemicals. Properties linked to drug-related crimes often contain sharps like scalpels or needles.
What Happens Immediately After Police Leave?
The police will investigate, secure, and document evidence. However, they don't perform blood cleanup services. When they set off, you should call professional crime scene cleaning companies.
Here are the benefits of getting Crime Scene, Hoarding, and Biohazard Cleanup professionals:
- Ensures a safe and meticulous cleanup
- Restores your property to pre-crime condition
- Stops cross-contamination and spread of pathogens
Crime scene cleanup needs expertise and precision. Knowing that you're working with experts will give you peace of mind.
What Are the Steps for Biohazard Cleanup?
Most people are unaware of how risky it is to deal with blood and bodily fluids. Coroner Talk reports that one in 24 people has Hepatitis B, Hepatitis C, or HIV. There is a risk of infection with these diseases if you don't follow the right biohazard cleanup procedure.
Assessment and Preparation of the Crime Scene
For a professional biohazard cleanup, your property is assessed and prepared. During assessment, document everything you see.
Proper assessment helps you determine the level of personal protective equipment you need. Some crime scenes, like blood and drug lab cleanup, may need more stringent precautions.
Biohazardous Containment and Control
The second essential step during cleanup is containment and control of the crime scene. This phase helps stop the spread of hazardous materials. As a result, it protects the cleanup professionals and the public from risky exposure.
Your cleanup crew will place physical barriers if there is a risk of airborne pathogens. These barriers may be tape or plastic sheeting that can isolate the biohazard.
For example, in an unattended death case, decomposition can release indoor environmental hazards that affect the air quality. During such a situation, containment becomes necessary. Once they securely contain the area, your crew will control the indoor environment.
Biohazardous Removal and Cleaning
Once they contain and control the hazardous waste, cleaning and removal start. Here are some cleanup and removal methods the cleaning crew may use:
- Blood: Use of absorbent tools, specialized cleaning agents
- Bodily fluids: Use disinfectants and biohazardous waste bags
- Airborne pathogens: Use HEPA filters to restore indoor air quality
- Body tissue remnants: Use enzymatic cleaners and mechanical equipment for removal
The biohazard remediation crew follows strict safety and health compliance when handling and disposing of these wastes. Since the risks involved are high, they use technical skill and pay attention to detail.
Sanitization and Disinfection of the Scene
After removing and cleaning the waste, they sanitize and disinfect the scene. Sanitizing the area helps reduce the presence of viruses and bacteria to safe levels. This process reduces the risk of potential infection.
Restoration of Your Space
Once everything is complete, restoration follows. The cleanup professionals will restore your space, ensuring it's safe and functional.
Frequently Asked Questions
Why Is Blood So Difficult to Remove from a Crime Scene?
Blood stains are challenging to remove from surfaces and fabrics. Knowing the composition of blood will help you know why they're stubborn to remove from various surfaces. Blood contains water, plasma, platelets, and red and white blood cells.
The iron content in hemoglobin is the major reason for staining. When blood drops on surfaces, it quickly joins with the fibers, creating stains that are hard to remove.
How Long Does DNA Last at a Crime Scene?
The lifespan of DNA depends on environmental conditions. In some indoor settings, DNA can stay for up to a year, which can allow for forensic DNA testing.
However, outdoor environments are harsher. UV rays from the sun can degrade DNA until it becomes unusable. As a result, DNA in outdoor areas has a shorter lifespan.
Cleaning does not necessarily remove DNA from a crime scene. While it removes the stains of fluids and bodily fluids, it may not remove all traces of DNA.
How Long Does Crime Scene Cleanup Take?
When a violent crime, death, or traumatic event happens, the aftermath is scary. If it happens on your property, you will want to know when the cleaners will be done.
Most crime scene cleanups can take between four hours and 72 hours. Your specific timeline will depend on the type of case, size of the area, and level of contamination. Complex cases like unattended deaths with decomposition can take a few days.
