How Are Crime Scenes Cleaned After An Incident

Crime scenes, from murder scenes to biohazards, present unique challenges that require professional intervention. The aftermath of such incidents can be overwhelming, especially for facilities managers or in-house cleaning supervisors unfamiliar with the intricacies of forensic cleaning.

This article explores the world of crime scene cleaners in the UK, shedding light on the meticulous process of restoring affected areas to their original state.

Who Handles Crime Scene Cleanup?

Crime scene cleanup is not a task for the faint-hearted. It demands professionals trained in handling biohazardous materials, understanding the health and safety implications, and equipped with personal protective equipment.

Typically, specialised companies like Perfect Clean, with expertise in biohazard cleanup, are entrusted with this responsibility, ensuring that crime scenes and trauma sites are professionally cleaned and sanitised.

The Crime Scene Cleanup Process

The crime scene cleanup process is systematic and thorough, ensuring that no trace of the incident remains.

Step 1 - Initial Assessment

Before any cleaning begins, a thorough assessment of the crime scene is conducted. This helps understand the extent of contamination, from blood and bodily fluids to other hazardous substances. The assessment guides the cleanup strategy and the resources required.

Step 2 - Safety First

Safety is paramount. Cleaners don personal protective equipment to shield themselves from potential biohazards. This includes gloves, masks, and protective suits, ensuring that they remain safe while cleaning.

Step 3 - Removal of Biohazardous Material

Biohazardous materials encompass a range of substances that pose a threat to human health. In the context of crime scenes, this often includes blood, bodily fluids, and sometimes even tissue remnants.The removal process is meticulous:
  1. Identification: Before removal, professionals identify all areas contaminated with hazardous substances. This ensures that no spot is overlooked.
  2. Collection: The crime scene cleaners carefully collect the biohazardous waste using specialised tools and equipment, ensuring minimal contact.
  3. Secure Disposal: These materials are placed in biohazard bags or containers once collected. It’s crucial to note that such waste cannot be disposed of like regular trash. They are taken to designated facilities where they are treated and disposed of in a manner that neutralises their threat, adhering to the control of substances hazardous to health regulations.
  4. Prevention: This step is not just about removal but also about preventing potential health risks. Ensuring complete removal significantly reduces the risk of disease transmission or other health hazards.

Step 4 - Deep Cleaning and Sanitization

After removing hazardous materials, the scene might look clean to the naked eye, but microscopic pathogens could still linger. The deep cleaning and sanitisation process ensures complete safety:

  1. Cleaning Agents: Specialised cleaning agents, specifically designed to combat biohazardous threats, are employed. These agents can break down stubborn residues and neutralise harmful pathogens.
  2. Advanced Equipment: High-grade equipment, such as steam cleaners, might be used to ensure that even the most challenging contaminants are eradicated.
  3. Attention to Detail: It’s not just about the obvious spots. Cleaners ensure that even hidden nooks and crannies, where contaminants might hide, are addressed. This includes cleaning under carpets, inside air vents, or other less-visible areas.
  4. Final Inspection: After the deep cleaning, a thorough inspection is conducted. This ensures that the affected area meets the stringent standards of cleanliness and is free from any potential biohazards.
  5. Odour Removal: Crime scenes, especially those left unattended for a while, can have lingering odours. The deep cleaning process also involves deodorising the area and restoring it to a neutral state.

Specialised Cleanup Situations

Beyond typical crime scenes, there are situations that demand specialised attention. Homicides, unattended deaths, and drug labs each present unique challenges. For instance, unattended deaths might involve decomposition, while drug labs could have chemical residues.

Each scenario requires a tailored approach to ensure complete cleanup, so it’s extremely important for a professional team to handle these cleanup situations.

Cost And Insurance In Scotland

Crime scene cleanup, especially in a region as diverse as Scotland, comes with its own financial considerations. Various factors can influence the cost, and understanding how insurance plays a role can be crucial for those seeking these services.

Factors Influencing Cost

  • The Severity of the Situation: A minor incident, such as a small biohazard spill, will typically cost less than a major crime scene with extensive contamination.
  • Location: Urban areas like Edinburgh or Glasgow might have different pricing structures compared to more remote locations in the Highlands. Accessibility and travel time can influence costs.
  • Specialised Equipment or Materials: Some situations might require unique cleaning agents or equipment, which can add to the overall expense.
  • Duration: The longer it takes to clean a scene, the higher the cost. This can be influenced by the complexity of the scene and the level of contamination.

Insurance Coverage in Scotland

  • Standard Coverage: Many insurance policies in Scotland cover crime scene cleanup, especially if it’s related to a home or business incident. This is often under the umbrella of ‘biohazard cleanup’ or ‘specialist cleaning services.’
  • Health and Safety Regulations: In Scotland, adherence to health and safety standards is paramount. If a location is deemed unsafe due to biohazards, insurance often covers the cleanup costs to ensure compliance with these regulations.
  • Consultation: It’s essential to consult with your insurance provider. While many policies cover crime scene cleanup, there might be stipulations, deductibles, or limits to be aware of. Some providers might also have a list of approved crime scene cleaners in Scotland, ensuring the work is done to a specific standard.
  • Government Assistance: In some instances, local councils or governmental bodies in Scotland might offer assistance or subsidies, especially if the incident has broader public health implications. It’s worth checking with local authorities to understand any available support.
