The Importance of Crime
Scene Evidence Preservation
• It is important for first responders to preserve
evidence so that investigators can identify and
successfully prosecute the guilty parties.
Operational Level
7–54
Guidelines for
Preserving Evidence
• Unless you must touch something, DON’T.
• Avoid disturbing areas not directly involved in
rescue activities.
• Remember what the scene looked like upon
first arrival as well as details about the
progression of the incident.
(1 of 3)
Operational Level
7–55
Guidelines for
Preserving Evidence
• Document your observations as quickly as you
can.
• Take photographs and videos of the scene as
soon as possible.
• When you must touch or move something,
remember what you did. In your report,
document where it was and where you put it. If
you can, photograph it before you do anything.
• Minimize the number of people working in the
area, if possible.
(2 of 3)
Operational Level
7–56
Guidelines for
Preserving Evidence
• Leave fatalities and their surroundings
undisturbed.
• Identify witnesses, victims, and the presence of
evidence.
• Preserve potentially transient physical evidence
(e.g., evidence present on victims, evidence
that may be compromised by weather
conditions such as chemical residue, body
fluids, or footprints).
(3 of 3)
Operational Level
7–57
Biological Attack Incidents
• Many people are potentially at risk
– Traditional first responders who transport ill
patients to medical facilities
– Health care workers who care for patients in
hospitals, residential facilities, outpatient settings,
at home, or elsewhere
– Laboratory personnel handling clinical specimens
– Health department staff who visit patients in or out
of health care facilities while conducting outbreak
assessment or control measures
(1 of 3)
Operational Level
7–58
Biological Attack Incidents
• First responders and others involved in patient
transport should take additional precautions.
– Run the ambulance ventilation system on its
highest setting using outside air circulation, which
will minimize air changes in the vehicle.
– For diseases that are transmitted by respiratory
transmission, the patient should wear a surgical
mask, disposable respirator, or, if needed for
respiratory support, an oxygen mask that does not
exhaust to ambient air.
(2 of 3)
Operational Level
7–59
Biological Attack Incidents
• First responders and others involved in patient
transport should take additional precautions.
– Responders transporting patients with different
diseases may require different levels of worker
respiratory protection.
(3 of 3)
Operational Level
7–60
Nuclear/Radiological Incidents
• Use radiation and contamination survey
instruments to determine radiation levels.
• Use the principles of time, distance, and
shielding to protect against radiation exposure.
• Stay away from ground zero. Enter the
surrounding area only to save lives, and only if
wearing appropriate PPE. Radiation levels may
be very high in these areas.
• Establish control zones like other incidents.
(1 of 4)
Operational Level
7–61
Nuclear/Radiological Incidents
• Isolate, evacuate, and/or shelter the public in
place as appropriate.
• Wear respiratory protection to reduce the dose
from inhalation of radioactive dust.
• Wear PPE. Standard firefighting gear or easily
removed outer clothing is sufficient to protect
from alpha and beta radiation, but it may not
protect against other environmental hazards.
(2 of 4)
Operational Level
7–62
Nuclear/Radiological Incidents
• Avoid skin contact with radioactive dust. Protect
open wounds or abrasions from radioactive
contamination by covering them.
• Do not eat, drink, chew, or smoke while
exposed to potentially radioactive dust or
smoke. When it is absolutely necessary to drink
water, drink from a canteen or other closed
container.
(3 of 4)
Operational Level
7–63
Nuclear/Radiological Incidents
• Remember that physical injuries are more
serious than radioactive contamination. Deal
with life-threatening conventional injuries first.
• Decontaminate.
(4 of 4)
Operational Level
7–64
Incendiary Incidents
• Only specially trained personnel should handle
incendiary devices discovered prior to ignition.
• If it is suspected that an incendiary device
started the fire, proper handling of potential
evidence is critical for crime scene
preservation.
Operational Level
7–65
Chemical Agent Incidents
• Expect at least a 5:1 ratio of unaffected to affected
•
•
•
•
casualties.
Decontaminate victims as soon as possible.
Disrobe victims from head to toe to decontaminate
successfully. The more clothing that can be removed,
the better.
Flush with water; generally this is the best mass
decontamination method.
Decontaminate after a known exposure to liquid
chemical agent as soon as possible to avoid serious
effects.
Operational Level
7–66
Chemical Agent Decontamination
Disrobing
Showering
Operational Level
