National EMS Education
Standard Competencies
Vehicle Extrication
• Safe vehicle extrication
• Use of simple hand tools
Introduction
• EMS departments
must be prepared
to respond to a
variety of special
rescue situations.
− Paramedics are
often first on the
scene.
Awareness
• All EMS providers require training in rescue
techniques.
− Focus of training is awareness.
− The paramedic’s function on-scene varies
depending on the company.
Awareness
• A technical rescue incident (TRI) is a
complex rescue incident.
• Three levels of TRI training:
− Awareness
− Operations
− Technician
Guidelines for Rescue
Operations
• Be safe.
• Follow orders.
• Work as a team.
• Think.
• Follow the golden rule of public service.
Steps of Special Rescue
• Preparation
• Access
• Response
• Disentanglement
• Arrival and scene
size-up
• Removal
• Stabilization of the
scene
• Transport
Preparation
• Train with other fire departments and
special rescue teams.
• Assess the following:
− Personnel and equipment
− Who will respond
− Familiarity with hazard area
Response
• If your department has its own TRI team, it
will respond.
− Often the rescue squad comes from an outside
agency.
− Contact utility companies as needed.
Arrival and Scene Size-Up
• Information received from initial dispatch
call is critical.
− Responders must:
• Identify/mitigate life-threatening hazards.
• Inform IC of special resources needed.
• Determine whether the situation is a search, rescue,
or recovery.
Stabilization of the Scene
• Be sure all hazards are identified.
• First arriving responder assumes command.
− Establish objectives.
− Coordinate resources.
− Unify command between agencies.
Stabilization of the Scene
• Three guidelines to follow:
− Approach the scene cautiously.
− Position apparatus properly.
− Assist specialized team members.
Stabilization of the Scene
• Emergency vehicles
− Safety is the primary consideration.
• Disrupting traffic creates a hazard.
• Emergency vehicles can act as a barrier.
• Use only essential warning lights.
Stabilization of the Scene
• Control zones
− An outer perimeter protects against public and
media; inner perimeter surrounds incident site
− Set up three control zones:
• Hot zone
• Warm zone
• Cold zone
Stabilization of the Scene

Gaining Access to the Patient
• Break tempered glass (cont’d).
− Wear proper PPE.
− First, lower the windows as far as possible.
− Aim for a low corner.
− Give other EMS personnel warning.
Gaining Access to the Patient
• Provide initial
medical care.
− Spine
immobilization
− Assessment and
management of the
ABCs
Disentangling the Patient
• Study the scene before taking action.
− The order of procedures will be determined by
the specifics of the incident.
− Main objective = maintain spinal alignment and
immobilization
Disentangling the Patient
• Air bag safety
− Identify
undeployed air
bags.
− Disable airbags by
disconnecting
power.
Disentangling the Patient
• Air bag safety (cont’d)
− Most vehicles contain an air bag.
− If the air bag has deployed, it is not a hazard.
− If it did not deploy, disconnect the battery.
− Some newer vehicles have a switch that allows
shutting off of the air bags.
Disentangling the Patient
• Air bag safety (cont’d)
− Do not place a hard object between the patient
and an undeployed air bag.
− Do not cut a steering wheel if the air bag has
not deployed.
− Never get in front of an undeployed air bag.
− Check for side-mounted air bags or curtains.
Disentangling the Patient
• Displacing the seat
− Relieves pressure
on the driver
− Gives rescuers
more room to work
− Try simple steps to
displace a seat.
Disentangling the Patient
• Removing the
windshield
− Allows for better
communication
− Remove in one
large piece.
− Essential before
removing the roof
Disentangling the Patient
• Removing the roof
− Increases space
for care and
disentanglement
− Protect the patient
and rescuers
inside the vehicle.
• Support the roof
when cutting posts.
Disentangling the Patient
• Displacing the
dash
− Use the dash roll
technique.
• Requires a
hydraulic cutter
and ram
− Must be done by a
trained rescuer

• Be aware of self-rescue techniques.
− Minimum PPE includes:
• Personal flotation device (PFD)
• Thermal protection
• Whistle
• If immersed in fast-moving water, adopt the
self-rescue position.
Water
• Cold water rescue
− Hypothermia can
quickly progress.
− Assume the heatescape-lessening
position (HELP).
− Patient may
survive underwater
due to the
mammalian diving
reflex.
Water
• Other water rescue
situations
− Special hazards of
surface water:
• Hydraulics
• “Strainers”
• Dams and
hydroelectric sites
Water
• Safe approach
− Wear appropriate PPE.

Spinal Injuries in Submersion
Incidents
• Suspect spinal injury if:
− Diving mishap or fall
− Unconscious patient with no information to rule
out neck injury
− Conscious patient reporting weakness,
paralysis, or numbness in arms and/or legs
− You have any other reason to suspect spinal
injury
Rope Rescue
• Types of rope rescue:
− Low-angle operations: slope of the ground is
less than 45°
− High-angle operations: slope of the ground is
greater than 45°
Rope Rescue
• Safe approach
− Set up equipment properly.
− Put distance between you and any loose
materials.

parking spot for the ambulance.
• Determine if there are injured patients or if
you are on stand-by.
Structure Fires
• Safe approach
− Stay with the ambulance.
− Remain present even after the fire is out.
• Unless transporting a patient or released by IC
Agricultural and Industrial
Rescue
• Visit local farms and industrial plants and
learn about:
− Equipment that is used
− How it operates
− How an operator can become entrapped
• Over time, protective shields and guards
may be damaged or removed.
Agricultural and Industrial
Rescue
• Safe approach
− Master cribbing.
− Take apart machines made of strong metal
(rather than cutting).
− Isolate the injury site.
Agricultural and Industrial
Rescue
• Safe approach (cont’d)
− Determine alternative methods of disentangling.
− Assess patient while rescue personnel plan
disentanglement.
− Be aware of differences in industrial and farm
settings.
Tactical Emergency Medical
Support
• Law enforcement
may call in the
SWAT team in
tactical situations.
− Tactical
paramedics
receive additional
training.

Tactical Emergency Medical
Support
• Tactical paramedics must be able to provide
medical care under adverse circumstances.
− Provide immediate medical care to persons who
become injured during an incident.
• Often before the scene is declared safe
Patient Care
• Many medical and trauma conditions are
assessed during the rescue process.
− Crush syndrome: Large muscle groups are
compressed for a prolonged period of time
• High-flow oxygen therapy or positive pressure
ventilations
• Administration of sodium bicarbonate, calcium
chloride, fluid bolus
Pain Management
• Use nonpharmacologic methods in the field
− Splinting
− Gentle handling
− Talking to patients
Medical Supplies

Summary
• “Rescue” means to deliver from danger or
imprisonment.
• The most difficult process in any rescue is
the coordination and balance of rescue and
treatment.
• A technical rescue incident (TRI) is a
complex rescue incident that requires
specially trained personnel and special
equipment.
Summary
• Technical rescue training occurs on three
levels: awareness, operations, and
technician.
• When assisting rescue team members:
−
−
−
−
Be safe.
Follow orders.
Work as a team.
Think.
− Follow the golden rule of public service.
Summary

Summary
• At a technical rescue incident, it is critically
important to slow down and properly
evaluate the situation.
• The first arriving officer at a rescue scene
should immediately assume command and
start using the incident management
system.
Summary
• Whenever possible, park emergency
vehicles in a manner that will ensure safety
and not disrupt traffic any more than
necessary.
• Accountability should be practiced at all
emergencies, no matter how small.
Summary
• Basket stretchers facilitate moving patients
to safety and can be used in a variety of
situations.
• Vehicle extrication is commonly necessary.
• There are many hazards associated with
alternative powered vehicles.
• You should have a thorough working
knowledge of the basic simple hand tools.
Summary
• Cribbing should be used regardless of the
position of the vehicle.
• Simple vehicle extrication techniques
include opening the door, breaking
tempered glass, and providing initial
medical care to the patients.
• During disentanglement, responders need
to be mindful of undeployed air bags.
Summary
• Many vehicle extrication techniques require
the use of specialized skills and training.
• A confined space is a location surrounded
by a structure that is not designed for
continuous occupancy.
• Confined spaces may have limited
ventilation to provide air circulation and
exchange.
Summary
• Trench rescues may become necessary
when earth is removed for placement of a
utility line or for other construction and the
sides of the excavation collapse.
• You should know how to properly don a
personal flotation device as well as how to
use the self-rescue position.
Summary
• Rope rescue incidents are divided into lowangle and high-angle operations.
• Wilderness search and rescue (SAR)
missions consist of two parts: looking for a
lost or overdue person and removing a
patient from a hostile environment.
• During lost person search and rescue, your
role is to stand by at the search base until
the lost person or people have been found.
Summary
• You should always stay with your
ambulance during a structure fire.
• If an incident develops into a tactical
situation, law enforcement agencies may
deploy use of specialized law enforcement
tactical units or the SWAT team.
• Pain control in rescue situations should take
the form of nonpharmacologic methods.
Summary
• A number of special patient packaging tools
are available to help extricate patients out of
their situation and up, down, or out to the
ambulance.
