A) Begin cleanup immediately to minimize health risks.
B) Secure the area and restrict access to authorized
personnel only.
C) Evaluate personal protective equipment (PPE)
requirements.
D) Document the scene with photographs for insurance
purposes.
Correct Answer: C
Rationale: The safety of the technician is paramount.
Evaluating PPE ensures that the technician is protected
from potential hazards before beginning the cleanup
process.
2. In the event of discovering an unknown liquid substance
at a crime scene, what is the recommended procedure?
A) Collect a sample for laboratory analysis.
B) Neutralize the substance using a universal absorbent.
C) Dilute the substance with water and mop it up.
D) Isolate the area and consult a hazardous materials
expert.
Correct Answer: D
Rationale: Isolating the area and consulting an expert
ensures proper identification and safe handling of
potentially hazardous materials.
3. According to the ANSI/IICRC S540 Standard, which of
the following is NOT a consideration when establishing a

A) Using double-bagged, biohazard-labeled containers.
B) Securing containers in an upright position during
transport.
C) Compressing waste bags to save space in the

against safety protocols.
7. In accordance with the ANSI/IICRC S540 Standard, what
is the minimum recommended procedure for cleaning a
non-porous surface contaminated with blood?
A) Wiping the surface with a cloth dampened with
disinfectant.
B) Applying an enzymatic cleaner and rinsing with water.
C) Using an EPA-registered disinfectant and following the
