Handling a homicide cleanup requires a unique combination of expertise, precision, and empathy. As someone certified in biohazard cleanup and trauma scene remediation, I understand the emotional weight and technical complexities that come with restoring a space after a traumatic event. At BioTechs, our goal is to ensure that families and property owners can begin to heal, knowing that the area has been cleaned, decontaminated, and made safe. If you’re wondering about the process behind a homicide cleanup, here’s a step-by-step look at how we approach this delicate task.
Homicides and other traumatic incidents can happen anywhere, from private homes in San Antonio’s neighborhoods to public spaces in areas like Live Oak or Boerne. Our team holds certifications such as IICRC Trauma and Crime Scene Technician (TCST) and OSHA’s 29 CFR 1910.1030 Workplace Bloodborne Pathogen Certification, giving us the tools and expertise necessary to handle these challenging environments while respecting the emotional needs of those involved.
Step 1: Securing the Scene and Initial Assessment
Once law enforcement completes their investigation and clears the scene, our work can begin. We start by conducting a full assessment of the site, taking note of visible and hidden biohazard risks, including blood, bodily fluids, and any damaged materials that might be contaminated.
Safety is paramount. Our first action is to establish secure containment barriers around the affected area. These barriers prevent any cross-contamination and protect those nearby from potential health risks associated with bloodborne pathogens. We’re meticulous in assessing every corner of the area since fluids can travel through unseen pathways like floorboards or crevices.
Step 2: Using Proper Personal Protective Equipment (PPE)
Our team prioritizes personal safety by using OSHA-compliant Personal Protective Equipment (PPE), which includes full-body suits, gloves, face shields, and respirators. These protective measures are crucial because biohazards left at a homicide scene can carry bloodborne pathogens such as HIV, Hepatitis B, and Hepatitis C. PPE ensures that our team members are fully protected while preventing any unintentional spread of contaminants.
At BioTechs, we adhere strictly to OSHA’s standards to protect our team and anyone in the vicinity, and we dispose of our PPE according to regulated procedures to ensure safety at every step.
Step 3: Removing Contaminated Materials and Items
Once the scene is secured and safety protocols are in place, we begin the cleanup process by carefully removing contaminated materials. This step involves identifying and disposing of any items that have absorbed fluids or other biohazards, including carpets, furniture, flooring, and sometimes even parts of the walls.
Our Advanced Trauma Cleaning and Decontamination certification ensures that we follow specific protocols for handling and disposing of these materials. Contaminated items are placed in biohazard bags, sealed, and disposed of according to EPA and OSHA regulations to prevent any risk of exposure or contamination to the surrounding environment.
Step 4: Applying Specialized Cleaning and Disinfectant Solutions
After removing contaminated materials, we thoroughly clean the remaining surfaces using EPA-approved disinfectants specifically designed to neutralize bloodborne pathogens. We apply our cleaning solutions carefully to every surface, ensuring that all pathogens are neutralized.
Our IICRC Trauma and Crime Scene Technician certification enables us to select and apply these disinfectants safely and effectively. We follow a rigorous decontamination process that goes beyond surface cleaning, addressing hidden contamination spots to restore full safety.
Step 5: Odor Treatment and Air Purification
In homicide scenes, odors are often an issue due to the presence of decomposing organic materials. Our team includes IICRC Odor Control Technicians (OCT), certified to handle odor treatment and help eliminate any lingering smells. We use specialized odor-neutralizing techniques to break down and remove odor-causing molecules, ensuring the space is not only visually clean but also free from any lingering reminders of the trauma.
In some cases, we may use air purifiers to circulate and filter the air, further reducing any residual odors and creating a more comfortable environment for anyone re-entering the area.
Step 6: Quality Check and Final Assessment
Before we consider the job complete, our team performs a final walkthrough to ensure all contaminants are fully removed and that every surface has been effectively decontaminated. Our goal is to leave no trace of biohazards, allowing families or property owners to re-enter the space with peace of mind.
This quality check includes verifying the cleanliness of hidden areas, confirming that all contaminated materials have been safely disposed of, and ensuring that any necessary odor treatment has been fully effective. If we detect any remaining issues, we address them before wrapping up.
Step 7: Documentation and Compliance Reporting
To provide transparency and peace of mind for families, property managers, or insurance providers, we document each stage of our cleanup process. This includes a report of contaminated items removed, the cleaning agents used, and the final results of our decontamination efforts.
Compliance with regulatory standards is key, so our documentation also serves as proof that the cleanup was conducted following OSHA, EPA, and IICRC guidelines. This level of detail is essential in San Antonio’s tightly regulated industry, particularly when dealing with insurance claims or legal considerations after a traumatic event.
