Crime scene cleanup is a term applied to cleanup of blood, bodily fluids, and other potentially infectious materials (OPIM). It is also referred to as biohazard remediation, and forensic cleanup, because crime scenes are only a portion of the situations in which biohazard cleaning is needed. Incidents which may require this type of cleanup include accidents, suicide (or attempted suicide), homicides, and decomposition after unattended death, as well as mass trauma, industrial accidents, infectious disease contamination, animal biohazard contamination (e.g. feces or blood) or regulated waste transport, treatment, and disposal.
Television productions like CSI: Crime Scene Investigation have added to the popularity of the term "crime scene cleanup". Australia, Canada and England have added it to their professional cleaning terminology. [1] As a profession, it is growing in popularity because of media exposure and the growth of training programs worldwide. [2]
The generic terms for crime scene cleanup include trauma cleaning, crime and trauma scene decontamination ("CTS Decon"), biohazard remediation, biohazard removal, and blood cleanup. The state of California refers to individuals who practice this profession as Valid Trauma Scene Waste Management Practitioners. [3]
Crime scene cleanup includes blood spills following an assault, homicide or suicide, tear gas residue, and vandalism removal/cleanup. There are many different sub-segments, named primarily after additional collateral, contingency, or preconditions, regarding the presence of non-blood borne organics, toxic irritants (e.g., tear gas) or disease vectors. However, it is the legality of charging a fee for mitigating potentially harmful biohazard situations that differentiates a registered crime or trauma practitioner from any general restoration, carpet cleaning, janitorial or housekeeping service. [4]
Human blood can carry deadly diseases like HIV/AIDS, Hepatitis B, and Hepatitis C. [5] When cleaning up blood, it's important to treat every blood spill as if the substance is infected. By using these precautions it will provide an extra layer of safety.
Crime scene cleanup began primarily as a local or regional small business activity but maturity and consolidation has created some larger entities in the industry; only a few nationwide companies exist, although some national carpet cleaning and restoration company franchises have added crime scene cleanup and biohazard removal to their services.
While the field of crime scene cleanup is not specifically regulated as a class, most, if not all, of the activities performed by biohazard cleanup teams in the United States are regulated or fall under best practice guidelines from governing and advisory bodies such as OSHA, NIOSH, DOT, and EPA. Those who hire a crime scene cleanup company should ensure they are properly trained in applicable federal and state regulations and can provide documentation of proper biohazardous waste disposal from licensed medical waste transportation and disposal companies. The client should confirm that the company is registered with the state Department of Health in California, Florida, and Georgia. A few states, such as California and Georgia (Georgia's Law), are the only states that explicitly require registration or licensing for crime scene cleanup. Other states may require biohazardous waste transport permits from the DOT.
In the US, OSHA requires limiting exposure to blood-borne pathogens as much as possible due to the assumption that the blood and biological material is infectious. Most actions to limit exposure fall under cross-contamination protocols, which provide that certain actions be taken to avoid further spreading the contamination throughout otherwise clean areas. Before beginning work on any trauma scene, CTS De-con companies should have an exposure control plan. Under employee safety and cross-contamination protocols, OSHA's Hazardous Waste Operations and Emergency Response (HAZWOPER) 29 CFR 1910.120 and Bloodborne pathogens 29 CFR 1910.1030 regulations pertain to bioremediation.
In the UK, biohazards are regulated in part by HSE. [6] Canada has published Canadian Biosafety Standards and Guidelines. [7]
The crime scene cleaners' work begins when the coroner's office or other officials, or government body "releases the scene" to the owner or other responsible parties. Only when the investigation has completely terminated on the contaminated scene may the cleaning companies begin their task.
Standard operating procedures for the crime scene cleanup field often include methods for decontaminating internal and external environments. Universal precautions recognized worldwide are the cautionary rule-of-thumb for this field of professional cleaning. For example, the personnel involved in the cleanup are expected to wear shoe covers, liquid impermeable coveralls, and protective eyewear. [8] Wearing protective gloves and the use of specifically rated cleaning agents are also mandatory policies to ensure that the infectious agents such as hepatitis and HIV are killed. [9] There are organizations that stress the avoidance of cleaning areas that officers cannot properly see to avoid accidental wounds such as needle punctures.
Cleaning methods for removing and sanitizing biohazards vary from practitioner to practitioner. Some organizations are working to create a "Standard of Clean," such as ISSA's K12 Standard, which includes the use of quantifiable testing methods such as ATP testing.
The American Bio Recovery Association (ABRA) [10] is the 3rd party credentialing body and membership organization for companies that specialize in this niche industry. Bio Recovery covers a bit more than the clean up of body fluids. Bio Recovery is the act of assessing risk, mitigating threats and remediating conditions resulting from the release of biological hazards. This may include crime and trauma mitigation (bloodborne and body fluids), suicide cleanup, outbreak response, zoonotic diseases, foodborne diseases, public health threats, illicit drugs and clandestine drug labs. ABRAs certification credentialing platform requires applicants to obtain prerequisite requirements prior to sitting for an independent exam. Questions on the exams are derived from the information in the required prerequisite and demonstrate retention of industry knowledge providing a high level of credibility. Member Companies of ABRA are held to the highest international standards for ethics and professionalism.
Three levels of Credentialing are available for industry career advancement from the American Bio Recovery Association include the Certified Bio Recovery Technician (CBRT), Certified Bio Recovery Supervisor (CBRS), and the Certified Bio Recovery Master (CBRM).
The Institute for Inspection Cleaning and Certification (IICRC) is the Standards development organization for the cleaning industry. It created the ANSI/IICRC S540 Standard for Trauma and Crime Scene Cleanup. The second revision is now released. The ANSI/IICRC S540 Standard defines criteria and methodology used by the technician for inspecting and investigating blood and other potentially infectious material (OPIM) contamination and establishing work plans and procedures. The Standard describes the procedures to be followed by professionals and the precautions to be taken when performing trauma and crime scene cleanup regardless of surface, item, or location. This standard assumes that all scenes have been released by law enforcement or regulatory agencies. The standard does not address "how" to cleanup crime scenes. It clearly states, “The S540 does not intend to attempt to teach remediation procedures, but rather provides the principles and foundation for understanding proper remediation practices. The S540 is not a substitute for remediation training and certification programs that are necessary to obtain competence in the field.” [11] International Sanitary Supply Association (ISSA) [12] is a global standards body and trade organization of professional janitorial and cleaning professionals.
Crime scene cleanup as a profession has been featured sporadically in popular culture and the media. [13] It first showed up in films when Quentin Tarantino produced Curdled , and later in films such as the Samuel L. Jackson film Cleaner , and the Amy Adams and Emily Blunt film Sunshine Cleaning . On television, it has been featured in a smattering of documentaries aired on the National Geographic Channel and the Discovery Channel, as well as reality series such as Grim Sweepers. The Korean drama series Move to Heaven follows a pair of cleaners who also examine the lives of the deceased they are hired to clean up after by collecting their personal belongings.
In print and online, the task has been the subject of Alan Emmins' book Mop Men: Inside the World of Crime Scene Cleaners, [14] and in a piece on "six figure jobs" that appeared on CNN. [15] Another book is Aftermath, Inc.: Cleaning Up after CSI Goes Home. [16] An extensive article on all aspects of crime scene cleanup was published in the forensic science section of Discovery's How Stuff Works. [17]
In crime scene cleanup video games, the main objective in the game is the process of the cleanup. An example is Viscera Cleanup Detail . [18] Viscera Cleanup Detail is a PC game distributed through Steam that enables players to clean up blood and body remains after a Sci-Fi battle has occurred on a space station. Another example of crime scene cleanup in video games is Safeguard. [19] Safeguard takes a more realistic and educational approach, enabling users to learn about the hazards of crime scene cleanup, as well as the equipment and tools used. [20] Safeguard also uses virtual reality to immerse users in the crime scene environment.
Some fictional depictions show crime scene clean-up involving criminal organizations. Crime fiction sometimes refers to the term "cleaner" as an expert in destroying and removing evidence, usually working for criminals. For example, if a murder has been committed, a cleaner is contracted to remove all traces of the crime as if it never happened. [21]
Biosafety is the prevention of large-scale loss of biological integrity, focusing both on ecology and human health. These prevention mechanisms include the conduction of regular reviews of biosafety in laboratory settings, as well as strict guidelines to follow. Biosafety is used to protect from harmful incidents. Many laboratories handling biohazards employ an ongoing risk management assessment and enforcement process for biosafety. Failures to follow such protocols can lead to increased risk of exposure to biohazards or pathogens. Human error and poor technique contribute to unnecessary exposure and compromise the best safeguards set into place for protection.
A biosafety level (BSL), or pathogen/protection level, is a set of biocontainment precautions required to isolate dangerous biological agents in an enclosed laboratory facility. The levels of containment range from the lowest biosafety level 1 (BSL-1) to the highest at level 4 (BSL-4). In the United States, the Centers for Disease Control and Prevention (CDC) have specified these levels in a publication referred to as BMBL. In the European Union, the same biosafety levels are defined in a directive. In Canada the four levels are known as Containment Levels. Facilities with these designations are also sometimes given as P1 through P4, as in the term P3 laboratory.
A biological hazard, or biohazard, is a biological substance that poses a threat to the health of living organisms, primarily humans. This could include a sample of a microorganism, virus or toxin that can adversely affect human health. A biohazard could also be a substance harmful to other living beings.
Cleaning is the process of removing unwanted substances, such as dirt, infectious agents, and other impurities, from an object or environment. Cleaning is often performed for aesthetic, hygienic, functional, safety, or environmental protection purposes. Cleaning occurs in many different contexts, and uses many different methods. Several occupations are devoted to cleaning.
A blood-borne disease is a disease that can be spread through contamination by blood and other body fluids. Blood can contain pathogens of various types, chief among which are microorganisms, like bacteria and parasites, and non-living infectious agents such as viruses. Three blood-borne pathogens in particular, all viruses, are cited as of primary concern to health workers by the CDC-NIOSH: HIV, hepatitis B (HVB), & hepatitis C (HVC).
Environmental remediation is the cleanup of hazardous substances dealing with the removal, treatment and containment of pollution or contaminants from environmental media such as soil, groundwater, sediment. Remediation may be required by regulations before development of land revitalization projects. Developers who agree to voluntary cleanup may be offered incentives under state or municipal programs like New York State's Brownfield Cleanup Program. If remediation is done by removal the waste materials are simply transported off-site for disposal at another location. The waste material can also be contained by physical barriers like slurry walls. The use of slurry walls is well-established in the construction industry. The application of (low) pressure grouting, used to mitigate soil liquefaction risks in San Francisco and other earthquake zones, has achieved mixed results in field tests to create barriers, and site-specific results depend upon many variable conditions that can greatly impact outcomes.
A needlestick injury is the penetration of the skin by a hypodermic needle or other sharp object that has been in contact with blood, tissue or other body fluids before the exposure. Even though the acute physiological effects of a needlestick injury are generally negligible, these injuries can lead to transmission of blood-borne diseases, placing those exposed at increased risk of infection from disease-causing pathogens, such as the hepatitis B virus (HBV), hepatitis C virus (HCV), and human immunodeficiency virus (HIV). In healthcare and laboratory settings globally, there are over 25 distinct types of blood-borne diseases that can potentially be transmitted through needlestick injuries to workers. In addition to needlestick injuries, transmission of these viruses can also occur as a result of contamination of the mucous membranes, such as those of the eyes, with blood or body fluids, but needlestick injuries make up more than 80% of all percutaneous exposure incidents in the United States. Various other occupations are also at increased risk of needlestick injury, including law enforcement, laborers, tattoo artists, food preparers, and agricultural workers.
Infection prevention and control is the discipline concerned with preventing healthcare-associated infections; a practical rather than academic sub-discipline of epidemiology. In Northern Europe, infection prevention and control is expanded from healthcare into a component in public health, known as "infection protection". It is an essential part of the infrastructure of health care. Infection control and hospital epidemiology are akin to public health practice, practiced within the confines of a particular health-care delivery system rather than directed at society as a whole.
Hazardous Waste Operations and Emergency Response is a set of guidelines produced and maintained by the Occupational Safety and Health Administration which regulates hazardous waste operations and emergency services in the United States and its territories. With these guidelines, the U.S. government regulates hazardous wastes and dangerous goods from inception to disposal.
An occupational hazard is a hazard experienced in the workplace. This encompasses many types of hazards, including chemical hazards, biological hazards (biohazards), psychosocial hazards, and physical hazards. In the United States, the National Institute for Occupational Safety and Health (NIOSH) conduct workplace investigations and research addressing workplace health and safety hazards resulting in guidelines. The Occupational Safety and Health Administration (OSHA) establishes enforceable standards to prevent workplace injuries and illnesses. In the EU, a similar role is taken by EU-OSHA.
The Illinois Environmental Protection Agency of the state of Illinois is the primary body concerned with the protection of the environment for the state. The Illinois EPA's mission is "to safeguard environmental quality, consistent with the social and economic needs of the State, so as to protect health, welfare, property and the quality of life."
Biomedical waste or hospital waste is any kind of waste containing infectious materials generated during the treatment of humans or animals as well as during research involving biologics. It may also include waste associated with the generation of biomedical waste that visually appears to be of medical or laboratory origin, as well research laboratory waste containing biomolecules or organisms that are mainly restricted from environmental release. As detailed below, discarded sharps are considered biomedical waste whether they are contaminated or not, due to the possibility of being contaminated with blood and their propensity to cause injury when not properly contained and disposed. Biomedical waste is a type of biowaste.
Aftermath Services, a ServiceMaster company, performs crime scene clean up, homicide cleanup, suicide cleanup, hoarding cleanup, unattended death cleanup, infectious disease disinfection, and other trauma cleanup and specialty biohazard cleaning services such as hoarding and tear gas cleanup. Headquartered in Aurora, IL, the company has been in business since 1996 and maintains locations serving 48 of the United States. The company pioneered its field and was the subject of a book by the same name. The company manufactures proprietary cleaning agents engineered specifically for cleaning biomatter and bodily fluids.
Brownfields are defined by the Environmental Protection Agency (EPA) as properties that are complicated by the potential presence of pollutants or otherwise hazardous substances. The pollutants such as heavy metals, polychlorinated biphenyls (PCB), poly- and per-fluoroalkyl substances (PFAS), and volatile organic compounds (VOCs) contaminating these sites are typically due to commercial or industrial work that was previously done on the land. This includes locations such as abandoned gas stations, laundromats, factories, and mills. By a process called land revitalization, these once polluted sites can be remediated into locations that can be utilized by the public.
Advanced Bio-Treatment (ABT) is a biohazard response and remediation company operating in twenty-eight states. The company employs a multitude of cleanup teams specializing in crime scene cleanup. Day-to-day business operations are overseen by a customer service driven team from the company’s corporate office located in Jacksonville, Florida.
Operations Plus WMD is a training level in dealing with hazardous materials.
Between 1947 and 1977, General Electric polluted the Hudson River by discharging polychlorinated biphenyls (PCBs) causing a range of harmful effects to wildlife and people who eat fish from the river. Other kinds of pollution, including mercury contamination and cities discharging untreated sewage, have also caused problems in the river.
Bio Recovery is an American company that handles crime scene and bio-hazard cleanups. The company assisted in the clean-up of the apartment of Craig Spencer, who worked with Doctors Without Borders, when he contracted Ebola, as well as a bowling alley he visited in New York.
The National Crime Scene Cleanup Association is an American company, owned by Prestige Worldwide Ind Corp., that provides crime scene cleanup, hoarding cleanup training, trauma cleanup training, unattended death cleanup training, as well as various types of remediation service training, such as mold, tear gas, or methamphetamine laboratories. Their crime scene cleaners are licensed professionals.
