CRIME SCENE INVESTIGATION EXAMS SET 2025/2026
QUESTIONS WITH ANSWERS MARKED A+
✔✔"Relevant and Reliable" standard of Daubert - ✔✔Prior to acceptance of expert
testimony the jusdge must determine if the reasoning or methodolog underlying the
testimony is scientifically valid and can be applied to the facts at issue
✔✔Chain of custody - ✔✔usually referes to the documentation of the location of all
physical evidence at all times
✔✔Every action must be documented in what ways... - ✔✔notes, photographs,
sketches, and reports
✔✔The purpose of documentation is to - ✔✔create a permanent record of the condition
of the crime scene and the physical evidence
✔✔Four stages that must be completed during documentation include: - ✔✔1. taking
notes 2. videography 3. photography 4. sketching
✔✔Photo log indicates: - ✔✔time and date, roll number, camera settings, distane to the
subject, and a brief describtion.
✔✔ASLD - ✔✔American Society of Crime Lab Directors
✔✔Is the control included in final laboratory results? - ✔✔the control will be documented
and included in final laboratory results
✔✔PPE - ✔✔Personal Protective Equipment
✔✔SCBA - ✔✔Self-contained breathing apparatus
✔✔When establishing boundaries should they be smaller or larger? - ✔✔Always secure
a larger area and then reduce the area as additional information is determined
✔✔Cross contamination - ✔✔transfer of material between two or more sources of
physical evidence
✔✔Safety Measures - ✔✔*No eating, drinking, smoking, or using cell phones in the
crime scene
*Be alert for biological, chemical, environmental, or mechanical hazards
*Watch for sharp objects such as hypodermic needles, knives, razors, broken glass,
nails, exposed metal, or other objects
*Do not use the bathrooms at the crime scene
,*Never pick up broken glass with your hands. Use a brush and dust pan, tongs, forceps,
or tweezers and place the pieces in a secure container
*Place all syringes, needles, and other sharp objects in a puncture resistant container
with a biohazard waring label. Never recap or place covers such as erasers over
hypodermic needles.
*When searching confined spaces, use mirrors, flashlights, and other tools before
placing your hands in the space. Do not overlook the potential for poisonous spiders
and/or snakes in narrow or confined dark areas
*Always use caution in unknown environments. Exotic pets may pose a hazard-
poisonous snakes, scorpions, and spiders can startle the unsuspecting CSI
*Always wash your hands or other skin surfaces thoroughly and immediately if you
come in contact with any body fluid. The universal decontamination solution is a diluted
solution of bleach 1:10 or 70% isopropyl alcohol
✔✔Types of PPE - ✔✔Gloves, Tyvek suits, shoe covers, and eye and respiratory
protection are essential for ensuring personal safety.
✔✔OSHA - ✔✔Occupational Safety and Health Administration
✔✔Bloodborne pathogens - ✔✔are infectious disease causing microorganism that may
be found or transported in biological fluids. Treat all human blood and body fluids as
though they are potentially infectious.
✔✔Fluids other than blood that may contain pathogens include: - ✔✔urine, feces, tears,
sweat, nasal secretions, saliva, semen, vaginal secretions, breast milk, and vomitus.
Human body also contains cerebral spinal fluid as well as synovial (joints), Pleural
(chest), peritoneal (abdomen), amniotic and pericardial (heart) fluids that can carry
bloodborne pathogens.
✔✔Most common bloodborne pathogens - ✔✔Human Immunodeficiency Virus (HIV-
AIDS), Hepatitis, rabies, and sexually transmitted diseases.
✔✔Barrier protections include - ✔✔disposable gloves, lab coats or coveralls, and eye
and face protection.
✔✔Does PPE guarantee total protection from bloodborne pathogens - ✔✔PPE does not
reduce the hazard or guarantee total protection-it is used to minimize the exposure or
contact with potentially hazardous materials
✔✔Nitrile gloves - ✔✔Chemical resistant
✔✔When should you change gloves - ✔✔frequently to reduce the possibility of cross
contamination. Immediately if they become punctured or torn
, ✔✔A face mask must be used with what? - ✔✔with goggles or safety glasses-it does
not provide adequate protection if used alone
✔✔Most ccommon route of exxposure for most matterials that are health hazards?? -
✔✔Inhalation
✔✔Airborne contaminants may be - ✔✔dust, aerosol, smoke, vapor, gas, or fumes
✔✔A disposable dust/surgical mask will fillter what? - ✔✔will filter out large particulate
matter, but does not provide repiratory protection from chemical vapors or biological
contaminants.
✔✔What type of respirator is required for the CSI to work in a potentially contaminated
enviornment? - ✔✔Air purifying respirator (APR)
✔✔HEPA - ✔✔High-efficiency particulate air (HEPA) filter attached to the APR provides
additional protection as air is drawn through the filter by the wearer.
✔✔Indirect contamination of your face can occur how? - ✔✔Touching or rubbing your
face with contaminated gloves
✔✔Disposable lab coats or Tyvek coveralls provide protection against what? -
✔✔Biological contamination
✔✔Light sourcce eyewear must guard against what? - ✔✔The maximum operating
wavelength of the laser source
✔✔Cyanide has what odor? - ✔✔Almond ordor
✔✔Rotten eggg odor indicates? - ✔✔Hydrogen Sulfide. Hydrogen sulfide is more toxic
than hydrogen cyanide
✔✔HazCom - ✔✔Hazard communication
✔✔For HazCom yourr employers mmust - ✔✔1. Develop, implement, and maintain at
each workplace a written hazard communication program
2. Compile a list of every chemical that is in use with MSDSs on each
3. List the methods or procedures the employeee will perform that iincolves thhe use of
chemicals. Precautionary measures must be included in the Hazzcom program. Written
protocols must be establiished that ensure that appropriate emergenccy procedures are
in place in th event of an acciident.
✔✔HMIS - ✔✔Hazardous Materials Identification System-chemicals must be properly
labeled with appropriate hazard warnings labels
