The techniques go beyond standard cleaning to eliminate odors at their source, often using industrial-grade equipment and following strict safety and disposal protocols mandated by the EPA and OSHA. 

 

Why Professional Odor Removal is Necessary Odors at a crime or trauma scene, particularly those stemming from decomposition or bodily fluids, are caused by bacteria and off-gassing from chemical processes (e.g., cadaverine and indole).

These smells are persistent and are a warning sign that hazardous contaminants, such as bloodborne pathogens (e.g., HIV, Hepatitis B and C), may still be present. 

 

Standard household cleaners and air fresheners are ineffective for these strong odors and cannot eliminate the underlying health risks. Professionals use specific techniques to ensure the area is safe and habitable again. 

 

Key Tools and Techniques

The process for forensic odor removal is meticulous and multi-staged, focusing on source removal and neutralization: 

• Initial Assessment and Containment: Technicians first assess the scene and contain the affected area using plastic sheeting or other barriers to prevent cross-contamination.
• Biohazard Removal: The primary source of the odor all bodily fluids, contaminated furnishings, carpeting, and even structural materials like subflooring is physically removed from the scene. 
• These materials are then secured in approved hazmat containers and transported to licensed biohazard disposal facilities.
• Cleaning and Disinfection: The remaining surfaces are cleaned using specialized, hospital-grade, EPA-approved disinfectants and enzyme-based cleaners that break down organic matter at a molecular level.
• Industrial Deodorization Equipment: After the source is removed and the area is cleaned, specialized equipment is used to neutralize lingering odor molecules:
  • Ozone Generators: These powerful machines produce ozone (O3), which oxidizes and destroys odor-causing molecules. The area must be sealed and unoccupied during use as ozone is harmful to humans and pets.
  • Hydroxyl Generators: These use UV light to create hydroxyl radicals that neutralize odors and are safer for use in occupied spaces than ozone machines.
  • Air Scrubbers: These devices use HEPA filters to remove airborne particulates and gases.
  • Foggers: These disperse industrial-strength deodorizing agents into the air and hard-to-reach areas like air ducts to neutralize odors on contact.
• Sealing: In some severe cases where odors have deeply penetrated porous structural elements, sealing the surfaces with a specialized odor-covering paint may be necessary to lock in any remaining particles.
• Verification: The process concludes with testing (such as ATP testing for biological matter) to ensure the area has met stringent decontamination standards and is safe.
