Question 1: What is the primary objective of trauma and crime scene cleanup
according to the ANSI/IICRC S540 Standard?
A. To quickly remove visible stains regardless of safety protocols
B. To safely and thoroughly remove biological and hazardous materials while restoring
the site to a sanitary condition
C. To preserve evidence for law enforcement only
D. To minimize cost regardless of safety standards
CORRECT ANSWER: B. To safely and thoroughly remove biological and
hazardous materials while restoring the site to a sanitary condition
Rationale: The primary objective of trauma and crime scene cleanup is to safely and
thoroughly remove biological and hazardous materials while restoring the site to a
sanitary condition. This includes decontamination, odor removal, and ensuring the
health and safety of occupants. The S540 Standard emphasizes that physical removal of
contaminants is the primary means of remediation .
Question 2: Which organization published the Standard of Care for trauma and
crime scene cleanup and decontamination work?
A. OSHA (Occupational Safety and Health Administration)
B. EPA (Environmental Protection Agency)
C. IICRC (Institute of Inspection, Cleaning and Restoration Certification)
D. CDC (Centers for Disease Control and Prevention)
CORRECT ANSWER: C. IICRC (Institute of Inspection, Cleaning and
Restoration Certification)
Rationale: The IICRC published the Standard of Care for trauma and crime scene
cleanup and decontamination work, known as the ANSI/IICRC S540 Standard. This
standard provides guidance and protocols for crime scene and trauma cleanup
procedures, establishing the accepted standard of care for the industry .
Question 3: What is the ANSI Standard for Trauma and Crime Scene Cleanup
known as?
A. OSHA 1910.1030
B. S540
,C. EPA 40 CFR
D. NFPA 701
CORRECT ANSWER: B. S540
Rationale: The ANSI/IICRC S540 Standard is the official standard for trauma and crime
scene cleanup. It provides guidance and protocols for crime scene and trauma cleanup
procedures, establishing the accepted standard of care for the industry .
Question 4: According to the S540 Standard, what is the primary means of
remediation for blood and OPIM?
A. Chemical disinfection only
B. Physical removal
C. UV light treatment
D. Thermal sterilization
CORRECT ANSWER: B. Physical removal
Rationale: The S540 Trauma Scene Standard establishes the principle that physical
removal of blood and OPIM is the primary means of remediation. Physical removal is
more effective than simply applying biocides because it eliminates the contaminated
material entirely .
Question 5: The ANSI/IICRC S540 Standard assumes what about all scenes
before cleanup begins?
A. That the scene has been fully decontaminated
B. That all scenes have been released by law enforcement or regulatory agencies
C. That the property owner has waived all liability
D. That insurance coverage has been verified
CORRECT ANSWER: B. That all scenes have been released by law enforcement
or regulatory agencies
Rationale: The S540 Standard explicitly assumes that all scenes have been released by
law enforcement or regulatory agencies before cleanup work begins. This is a critical
prerequisite for technicians to ensure they are not interfering with an active
investigation .
Question 6: What is the first concern of all trauma scenes according to IICRC
guidelines?
A. Speed of cleanup
B. Personal safety
C. Cost containment
D. Evidence preservation
CORRECT ANSWER: B. Personal safety
, Rationale: Personal safety is the most significant concern in trauma scene cleanup
because the health status of the body fluids and potential pathogens are unknown.
Technicians must prioritize their own safety before any cleaning activities begin .
Question 7: Under the US Federal Government, which organization sets
workplace safety standards for trauma cleanup?
A. EPA (Environmental Protection Agency)
B. CDC (Centers for Disease Control and Prevention)
C. OSHA (Occupational Safety and Health Administration)
D. NIOSH (National Institute for Occupational Safety and Health)
CORRECT ANSWER: C. OSHA (Occupational Safety and Health
Administration)
Rationale: OSHA (Occupational Safety and Health Administration), under the
Department of Labor, sets safety standards for workplace safety, including regulations
that apply to trauma and crime scene cleanup such as the Bloodborne Pathogens
Standard .
Question 8: What does OPIM stand for in the context of trauma and crime
scene cleanup?
A. Other Potentially Infectious Materials
B. Organic Pathogenic Infectious Matter
C. Operational Procedures for Infection Management
D. Occupational Pathogen Isolation Methods
CORRECT ANSWER: A. Other Potentially Infectious Materials
Rationale: OPIM stands for Other Potentially Infectious Materials. The S540 Standard
defines criteria and methodology for inspecting and investigating blood and Other
Potentially Infectious Material (OPIM) contamination .
Question 9: Which of the following is NOT a component of trauma and crime
scene cleanup described in the S540 Standard?
A. Principles of Trauma and Crime Scene Cleanup
B. Safety and Health
C. Antimicrobial (Biocide) Technology
D. Financial Billing Procedures
CORRECT ANSWER: D. Financial Billing Procedures
Rationale: The S540 Standard describes specific components including Principles of
Trauma and Crime Scene Cleanup, Safety and Health, Antimicrobial Biocide
Technology, Administrative Procedures, and others. Financial billing procedures are not
part of the standard's technical protocols .
Question 10: According to OSHA's Bloodborne Pathogens Standard, Universal
Precautions require that:
