What Is Biohazard Cleanup?


Some biological substances, such as bacteria, bodily fluids, and other biological agents, require specialised cleaning to protect human health and the environment.

Specialised cleaning isn’t just advisable – it’s often legally required. Many UK laws, such as the Hazardous Waste Regulations of 2005 and the Environmental Protection Act of 1990, dictate specific standards for executing biohazard cleanups.

Professional biohazard cleaning and removal services encompass a range of crucial tasks, from sanitising and disinfecting to safely disposing of contaminated materials. Such measures should always be handled by experienced technicians with biohazard training.

What Is Biohazardous Waste?

Biohazard waste refers to any material containing biological substances that may threaten human health or the environment. Common examples include…

  • Bodily fluids: Blood, saliva, vomit, urine, and feces from humans or animals.
  • Bloodborne pathogens: Pathogenic microorganisms that can be transmitted through blood, such as HIV, hepatitis B, and hepatitis C viruses.
  • Animal waste: Feces, urine, and other bodily fluids from animals
  • Microbiological cultures: Specimens, cultures, and stocks of infectious agents used in laboratories or medical facilities.
  • Sharps: Needles, syringes, scalpels, and other sharp objects contaminated with blood or bodily fluids.
  • Pathological waste: Tissues, organs, and body parts removed during surgery or autopsy, as well as specimens from medical procedures.

There are also different classifications for biohazardous materials based on the risk they pose. The two main classification systems often used are:

(1) Risk Group (RG) Classification

This classification system categories biological agents into four risk groups based on their pathogenicity and the severity of the diseases they cause.

  • Risk Group 1 (RG1): Biological agents in this group pose the lowest risk to human health. They are unlikely to cause disease in healthy individuals and do not typically spread easily.
  • Risk Group 2 (RG2): These agents pose a moderate risk to human health and can result in diseases, but the risk of transmission is limited. Examples include common pathogens such as Salmonella, influenza viruses, and some strains of E. coli.
  • Risk Group 3 (RG3): This group encompasses biological agents that can cause severe or potentially fatal diseases. Examples include Mycobacterium tuberculosis, human immunodeficiency virus (HIV), and certain strains of the influenza virus.
  • Risk Group 4 (RG4): These biological agents pose the highest risk of severe or life-threatening diseases. Transmission is often rapid, and strict containment measures are required. Examples include Ebola virus and the Marburg virus.

These risk groups help guide the development of appropriate safety protocols, containment measures, and research practices for handling biohazardous materials.

(2) Biosafety Level (BSL) Classification

This system categorises laboratories and facilities based on the level of biocontainment required to handle certain substances. It consists of the following four levels:

  • Biosafety Level 1 (BSL-1): BSL-1 laboratories handle agents that pose minimal risk to laboratory workers and the environment. These agents are typically not known to cause disease in healthy humans.
  • Biosafety Level 2 (BSL-2): BSL-2 laboratories handle agents that pose moderate risks. As a result, they employ additional safety measures, such as restricted access, biohazard warning signs, and personal protective equipment (PPE).
  • Biosafety Level 3 (BSL-3): BSL-3 laboratories handle agents that pose serious risks and require stringent containment measures, including ventilation systems and double-door access.
  • Biosafety Level 4 (BSL-4): BSL-4 labs handle the riskiest biological agents. These have the highest level of containment, with specialised engineering controls and stringent safety protocols. Access is highly restricted, and personnel require extensive training and experience.

BSL classifications help make sure that appropriate safety measures are implemented to prevent accidental exposure and release of biohazardous materials.

Situations Requiring Biohazard Cleanup

There are many situations in which biohazard cleaning services may be necessary. Some of the most common instances involve…

Crime Scenes
After violent crimes, such as homicides, assaults, or suicides, biohazard cleanup is necessary to safely remove blood, bodily fluids, and other potentially infectious materials from the scene.

Unattended Deaths
When a person dies alone and their body is not immediately discovered, decomposition can occur, resulting in biohazardous conditions. Professional cleaning is needed to safely decontaminate the area, remove odors, and mitigate risks.

Mold Infestations
Mold growth in indoor environments can produce allergens, irritants, and potentially toxic substances. Biohazard cleanup involves removing mold-infested materials, then cleaning and disinfecting the affected surfaces.

Hoarding Cleanup
Hoarding situations involve the excessive accumulation of waste, debris, and biohazardous materials, such as rotting food, feces, and urine. Professional cleanup services will safely remove clutter, decontaminate surfaces, and restore a safe living environment.

Infectious Disease Outbreaks
During outbreaks of contagious diseases, such as influenza or COVID-19, biohazard cleanup may be necessary to disinfect contaminated surfaces, healthcare facilities, or public spaces.

The Biohazard Cleanup Process

(1) Assessment
Professional cleaners will first assess the biohazardous situation. This allows them to identify the extent of contamination, potential hazards, and the necessary cleanup measures.

(2) Containment
To prevent the spread of contaminants, biohazard cleaners will cordon off the affected area. This minimises the risk of exposure to biohazardous materials and prevents cross-contamination of clean areas.

Personal Protective Equipment (PPE)
Before starting cleanup operations, all personnel must don appropriate PPE. This typically includes gloves, masks, goggles or face shields, protective clothing, and respirators.

The cleanup process involves cleaning, disinfecting, and decontaminating all affected surfaces, materials, and equipment using appropriate disinfectants and cleaning agents.

Removal and Disposal
Any contaminated clothing, waste, or debris will be carefully removed from the site and properly disposed of according to regulatory guidelines and waste management protocols.

After decontamination, the affected area will be thoroughly sanitised to eliminate any remaining pathogens and odors. This may involve fogging or misting with disinfectants, steam cleaning, or other methods.

Benefits of Hiring a Professional Biohazard Cleanup Company

Hiring a professional biohazard cleanup company does more than simply ensure the safe, effective handling of hazardous materials.

One of the key advantages lies in the expertise and experience of trained technicians. These professionals undergo extensive training in biohazard cleaning techniques and safety protocols. This enables them to properly assess and address biohazardous situations using the most effective methods and equipment.

Additionally, professional cleaning and disinfection protocols help prevent the spread of pathogens. Biohazard cleanup companies follow strict cleaning and disinfection procedures using disinfectants approved by the UK’s Environment Agency (EA).

Hiring a biohazard cleanup company also ensures facilities maintain compliance with legal and regulatory requirements. These companies are up-to-date on all the relevant laws and guidelines governing hazardous cleanups, including Health and Safety Executive (HSE) regulations and EA guidelines.

Choosing a Biohazard Cleanup Company

Start by verifying that the company is licensed and insured to perform biohazard cleanups in your area. Licensing demonstrates that the company meets specific standards set by local authorities while insurance protects in case of accidents or damages.

Experience is another critical factor to consider. Look for companies with a proven track record of handling different kinds of biohazardous situations, from crime scenes to infectious disease outbreaks.

It’s wise to obtain quotes from multiple biohazard cleaning companies to compare prices, services, and capabilities. While cost is important, you ultimately want to hire a team that’s reliable, safe, and highly experienced.

In Summary

Biohazard cleanup plays a vital role in safeguarding both public health and the environment. Many biological substances can pose significant threats, and hiring commercial cleaning services is the only way to confidently eliminate any risks.
