Search and Rescue
In a disaster, CERT teams assist with light search & rescueA team may be assigned to search
a particular building or area
LIGHT search & rescue = certHeavy rescue (collapsed building)
done by USAR professionals

People trapped after a disaster can survive hours or even days
The more quickly they are rescued the better their chance of survival

Search and Rescue Operations
1. Search Assess damage/size-up situation Locate victims. Document location.
2. Rescue Extricate victims Triage/stabilize Move victims Mark location as searched

Objectives Of Search And Rescue
• Rescue greatest number in shortest amount of time
• Rescue lightly trapped victims first
• Always protect rescuer safety
![Page 6: Search and Rescue Operations](https://reader034.vdocuments.mx/reader034/viewer/2022042703/56816912550346895de02cd9/html5/thumbnails/6.jpg)
Decision To Attempt Rescue
Risk involved to the rescuerMost important
person is rescuer!
Greatest good for greatest number of people

Assess Damage
• Three levels of damage• Light damage• Moderate damage• Major damage
![Page 10: Search and Rescue Operations](https://reader034.vdocuments.mx/reader034/viewer/2022042703/56816912550346895de02cd9/html5/thumbnails/10.jpg)
• LIGHT DAMAGE YES• MODERATE DAMAGE Cautiously• HEAVY DAMAGE NO

MODERATE DAMAGE Substantial damage in many
areasMultiple visible cracks in wallsSubstantial damage to interior
such asmany toppled furnishings, fallen ceilings

Wood Frame: light damage to masonry/chimneys
Pre-1940: House may slide off foundation
Hillside: ground failure and considerable damage
Single-Family Dwellings

![Page 36: Search and Rescue Operations](https://reader034.vdocuments.mx/reader034/viewer/2022042703/56816912550346895de02cd9/html5/thumbnails/36.jpg)
Listen Carefully3
• Stop periodically to listen for taps, movement or voices

Triangulate4
• Use flashlights to point towards victim sounds

Document Results7
Keep complete records both of removed victims and of victims who remain trapped or dead.
If you don’t document it It didn’t get
done!

Rescue Operations
Primary Functions:Creating a safe rescue environment
Lift objects out of the wayUse tools to remove objectsRemove debris
Triaging or stabilizing victimsRemoving victims
![Page 43: Search and Rescue Operations](https://reader034.vdocuments.mx/reader034/viewer/2022042703/56816912550346895de02cd9/html5/thumbnails/43.jpg)
Creating A Safe Environment• Maintain rescuer safety
• Triage in lightly damaged buildings
• Stabilize and evacuate victims quickly from moderately damaged buildings
Note: Never attempt a rescue from a stuck elevator

Removing Victims
Types of victim removal include ...• Self-removal or assist
• Lifts and drags
Allow victims to extricatethemselves when possible.
![Page 45: Search and Rescue Operations](https://reader034.vdocuments.mx/reader034/viewer/2022042703/56816912550346895de02cd9/html5/thumbnails/45.jpg)
Extrication MethodDepends upon ...
• General stability of immediate environment
• Number of rescuers available
• Strength and ability of rescuers
• Condition of victim
![Page 46: Search and Rescue Operations](https://reader034.vdocuments.mx/reader034/viewer/2022042703/56816912550346895de02cd9/html5/thumbnails/46.jpg)
Lifting/Cribbing
“Lifting” using a lever to lift an object.
“Cribbing” using boards, blocks etc. to stabilize something we have lifted
“Box Cribbing” arranging boards in a box configuration to stabilize heavy objects

Patient Carries
Assist a lightly injured person to walk
REMEMBER: Let the walking
wounded walk!

Patient Carries
Use a blanket to drag a victim
![Page 53: Search and Rescue Operations](https://reader034.vdocuments.mx/reader034/viewer/2022042703/56816912550346895de02cd9/html5/thumbnails/53.jpg)

Two Person Carry
This helps the rescuers maintain good control over the patient

Using the Evacu-Trac ChairThe Evacu-Trac brake is normally on. To descend the stairs, release the brake by slowly squeezing the brake lever. Descent speed can be slowed by reducing pressure on this lever. A governor limits the maximum descent speed to about 3' per second, allowing even a small attendant to safely transport heavier riders.
![Page 56: Search and Rescue Operations](https://reader034.vdocuments.mx/reader034/viewer/2022042703/56816912550346895de02cd9/html5/thumbnails/56.jpg)
Using the Evacu-Trac Chair
On stairs, the tracks securely grip the stair noses and control the descent speed regardless of the stair covering. On flat surfaces, Evacu-Trac can be pushed on its wheels as easily as a stroller. This features allows the user to be transported to an area clear of the emergency rather than to an area of refuge.
