FAQ – Cleaning after death, accident or crime scene
What are the risks involved in cleaning a crime scene?
Cleaning a crime scene involves serious risks such as
blood exposure, biological fluids,
persistent odors and hazardous waste.
Only trained professionals equipped with appropriate
PPE can safely perform disinfection
and decontamination.
What does a post-mortem cleaning technician do?
A post-mortem cleaning technician intervenes after a
death, an accident or a
crime. The mission includes
complete disinfection,
decontamination,
biohazard waste removal (DASRI)
and full property restoration.
This profession requires precision, discretion and respect for human dignity.
How does a disinfection intervention after death work?
Each post-death intervention follows a strict protocol:
sorting contaminated items,
DASRI waste collection,
full disinfection and
decontamination,
odor neutralization
and site securing to eliminate all health risks.
What is the difference between disinfection and decontamination?
Disinfection eliminates
bacteria, viruses
and pathogenic microorganisms.
Decontamination goes further by neutralizing
chemical, biological and physical contaminants
present in the environment.

What Sets Professional Crime Scene Cleanup Apart
Crime scene remediation is a regulated, specialized discipline that requires certified professionals equipped with the right protective gear, cleaning agents, and disposal protocols. Whether the scene involves a violent crime, an accident, or an unattended death discovered after the fact, the biological risks are significant — and cleaning must be performed before the property can be safely re-occupied.
At Défi Clean, our crime scene cleanup teams are trained in biohazard handling, DASRI waste management, and psychological first aid awareness. We operate across France with fully equipped vehicles and can mobilize within hours.
Types of Situations We Handle
Homicide and assault scenes: Post-violence cleanup requires removal of blood, biological fluids, and potentially embedded foreign matter from all affected surfaces. We work after law enforcement has completed their investigation and released the scene.
Accidental death: Accidents in the home — falls, medical emergencies — can leave behind biological contamination that must be professionally treated before family members or other occupants return.
Unattended death and decomposition: When a body is not discovered immediately, the cleanup challenge intensifies significantly. Decomposition fluids can penetrate flooring and walls, requiring structural assessment and sometimes partial demolition.
Industrial and road accident scenes: We also intervene on vehicle accident sites, industrial premises, and public spaces following traumatic events, coordinating with local authorities as required.
Our Cleaning and Decontamination Standards
Every crime scene cleanup intervention at Défi Clean follows a documented protocol aligned with French health and safety regulations. Our technicians wear full-body protective suits, respiratory protection, and double-gloves throughout the intervention. All biohazard waste is packaged in certified DASRI containers and transported to licensed disposal facilities.
We use a combination of enzymatic cleaners to break down organic matter, followed by hospital-grade virucidal and bactericidal disinfectants. In cases of confirmed or suspected presence of particularly dangerous pathogens, we apply additional decontamination protocols including UV treatment or hydrogen peroxide vapor.
Working With Families, Insurers, and Authorities
We understand that crime scene cleanup most often occurs in the context of a traumatic event affecting a family. Our approach is to be as transparent, communicative, and supportive as possible throughout the process. We provide detailed written reports and decontamination certificates required by insurance companies, notaries, and housing authorities.
We are experienced in working alongside police, gendarmerie, prosecutors’ offices, social services, and victim support organizations. Our intervention is entirely confidential — we never communicate with third parties without your explicit authorization.
Frequently Asked Questions
Can I clean a crime scene myself? This is strongly inadvisable. Exposure to blood and biological matter carries serious health risks including bloodborne disease transmission. Additionally, improper disposal of biohazardous material is an offense under French law. Professional intervention protects both health and legal compliance.
How long does a crime scene cleanup take? It depends on the size of the area and the severity of contamination. Most residential interventions take between 4 and 12 hours. Larger or more severely contaminated scenes may require multiple days.
Do you provide a written intervention report? Yes, always. Our decontamination certificate is recognized by insurers, notaries, and real estate professionals.
