When dealing with biohazard cleanup, especially in a place like San Antonio, it’s essential to understand the risks of cross-contamination. Cross-contamination occurs when hazardous materials spread from a primary area to other parts of a property, increasing the risk of exposure to harmful pathogens. As an ABRA Certified Bio-Recovery Master, I make it a priority to address and control these risks with each project our team undertakes.
What is Cross-Contamination?
In biohazard cleanup, cross-contamination happens when pathogens or harmful materials travel from one location to another, potentially endangering people and surfaces that were not initially impacted. This is not just limited to the immediate area where an incident occurred; airborne particles and improper handling can spread contaminants to new areas, increasing exposure risks.
Biohazard scenes contain a variety of potential hazards, including bloodborne pathogens like HIV, Hepatitis B, and Hepatitis C, which can survive on surfaces for days if not properly treated. The CDC states that pathogens like the Hepatitis B virus can survive outside the body for up to seven days under the right conditions. This means any cross-contamination can put individuals at risk long after the initial exposure if the area is not cleaned according to strict protocols.
Key Sources of Cross-Contamination in Biohazard Cleanup
Cross-contamination risks come from several primary sources:
- Airborne Particles
Bloodborne pathogens and bacteria can become airborne during cleanup processes, especially if the cleanup isn’t handled by trained professionals using proper personal protective equipment (PPE). The Occupational Safety and Health Administration (OSHA) outlines how airborne particles can spread pathogens. This is why our technicians wear respirators and follow OSHA’s 29 CFR 1910.1030 standards for controlling airborne exposure during cleanup. - Improper Handling of Contaminated Materials
Mishandling of contaminated materials, including clothing, furniture, and other surfaces, can spread pathogens to other areas. At BioTechs, we always employ full containment barriers to keep contaminants localized. This ensures that these hazardous materials don’t spread to other parts of the property, protecting both our team and future occupants of the space. - Use of Inadequate Cleaning Protocols
Using basic household cleaning supplies to attempt biohazard cleanup can spread contaminants rather than eliminating them. At BioTechs, we rely on IICRC-certified protocols for trauma and crime scene cleanup, ensuring thorough and effective cleanup methods. Our team is certified as an IICRC Trauma & Crime Scene Technician (TCST), giving us the expertise to handle biohazard materials safely and effectively. - Inadequate PPE (Personal Protective Equipment)
Not all PPE is created equal, and failing to use the right type or level of protection can lead to cross-contamination. Our team’s training and certifications, such as Hazardous Waste Operations and Emergency Response (HAZWOPER) and Respiratory Protection Program certifications, ensure that each team member is equipped with PPE that meets the highest industry standards. We follow ABRA’s best practices and adhere to stringent safety protocols to prevent cross-contamination.
How BioTechs Manages Cross-Contamination in San Antonio
The residents of San Antonio and surrounding areas like Boerne, Shertz, and Canyon Lake can trust our team to deliver thorough and safe biohazard cleanup. Here’s how we control cross-contamination risks on every project:
1. Setting Up Containment Zones
One of the most crucial steps we take is building full containment barriers around the affected area. Whether we’re working in a residential home, commercial space, or public area near landmarks like the San Antonio River Walk, we make sure our work doesn’t impact unaffected spaces. By containing the biohazard area, we minimize the spread of pathogens and keep the rest of the property safe.
2. Proper Disposal of Contaminated Materials
Our team follows OSHA and ABRA standards for the safe disposal of biohazardous waste. We double-bag and seal any contaminated materials, using state-approved disposal methods. For residents in Cibolo or Universal City, this means that when BioTechs cleans a biohazard scene, you can trust that waste is handled with the utmost care and in full compliance with all relevant regulations.
3. Thorough Application of Disinfectants
We use EPA-approved disinfectants on all surfaces within the containment area. Our IICRC Odor Control Technician (OCT) certification ensures that we address not only visible contaminants but also any odors that might be associated with biohazard scenes. Odor treatment is also essential in biohazard cleanup.
4. Monitoring Air Quality
In cases where there’s a significant risk of airborne pathogens, we utilize air scrubbers with HEPA filtration to trap airborne particles and prevent them from spreading. The use of HEPA air filtration aligns with OSHA guidelines, allowing us to maintain safer air quality both during and after cleanup.
The Importance of Professional Biohazard Cleanup Services
Cross-contamination in biohazard cleanup isn’t something to take lightly. If an area is not properly decontaminated, it can leave lingering risks for anyone who enters the property. The CDC, OSHA, and other organizations stress the importance of proper PPE, containment, and handling of biohazardous materials. Our commitment to these protocols is why we take training and certification so seriously. The residents of San Antonio and surrounding communities can rest assured that when BioTechs handles a cleanup, it’s done with the utmost care and precision.
For those who may be dealing with the aftermath of a traumatic event, it’s crucial to contact professionals trained and certified in biohazard cleanup. Our team is equipped to help you navigate the cleanup process with compassion, discretion, and a focus on safety. If you or someone you know is struggling with the emotional impact of a traumatic event, I encourage you to visit resources like the Alliance of Hope (allianceofhope.org) for support.
