Us r search terms and procedures

US&R Search Terms and Procedures

Relevant victim location information

Relevant Victim Location Information

  • Building use

    • Type of occupancy

    • Expected number of occupants

  • Time of day and day of week

  • Type of collapse

  • Associated hazards

  • Possible victim locations

Sources of information

Sources of Information

  • Pre-incident site plan

  • Size-up and reconnaissance information

  • Verbal reports

    • Rescued victims, co-workers, witnesses, relatives

  • Contractors and building engineers

Types of us r search

Types of US&R Search

  • Hasty Search (Primary Search)

    • Rapid assessment

    • Assists in size-up

    • Helps determine priorities

  • Extensive/Grid Search (Secondary Search)

    • Thorough systematic search

    • Redundant search

    • Verification of victim location with alternate resources

    • Confirms “exact” victim location

Us r search categories

US&R Search Categories

  • Categories

    • Physical search

    • US&R canine search

    • Technical search

  • Effectiveness of various categories of search types

Physical search

Physical Search

  • Deployment of personnel for physical search

  • Advantages

    • Resources readily available

    • No high tech equipment/procedures needed

    • Can use volunteers

    • Visual sighting provides victim location verification

Physical search1

Physical Search

  • Disadvantages

    • Only for surface victims

    • Best during only daylight hours

    • Dangerous for search personnel

    • May miss some victims

Hailing system procedures

Hailing System Procedures

  • Surround search site with personnel

  • Call for silence

  • Personnel call out one by one – use clockwise rotation

  • After each call out, ALL personnel listen for response and point to direction of sound

  • Triangulate on victim location – may have multiple “fixes”

Hailing system

Hailing System

  • Advantages

    • Resources readily available

    • No high tech equipment/procedures needed

    • Triangulates on victim location

    • Can be used day or night with relative safety

Hailing system1

Hailing System

  • Disadvantages

    • Effectiveness diminishes after time due to victims decreasing ability to respond

    • Additional search tactics may be needed to pinpoint the exact location of the victim

    • May not locate all victims in collapse

Physical search procedures

Physical Search Procedures

  • Organize personnel to search area

    • Requires team leader

    • Establish good communications with IC

    • Use buddy system

  • Use building plans to plot progress and direct teams

  • Use hailing procedure if appropriate

  • Use proper search marking procedures

  • Enter if structure is sound

Physical search options

Physical Search Options

  • Search in organized manner

  • Don’t skip any rooms unless areas is unsafe

    • Small Rooms or areas

      • “Go right - stay right” method

    • Large rooms or areas

      • Line - search method

Contact with victims

Contact with Victims

  • Encourage victims not to give up

  • Explain situation

  • Assess victim position, entrapment and medical condition

  • “Interview” victim about other occupants

  • Leave rescuer(s) with victim if safe

  • Continue search until all victims are accounted for

  • Report to IC with findings

Us r canine search

US&R Canine Search

  • Specially trained and certified canine and handler teams

    • Caution using other non-certified canines form PD or wilderness environment

    • Possible harm to handler, victims or canines to trained for urban collapse environments

Canine search

Canine Search

  • Advantages

    • Can cover large areas in a short time span

    • Used for both Hasty and Extended grid searches

    • Can detect deeply buried victims who are able to or not able to respond themselves

    • Can differentiate between live or dead victims

Canine search1

Canine Search

  • Disadvantages

    • Very limited number or available teams

    • Can be temperamental

    • Canines affected by weather and physical condition

    • Additional search modes may have to be used to confirm victim location

Technical search

Technical Search

  • Three primary types

    • Electronic listening devices

    • Visual search devices

    • Other electronic devices

  • Requires trained users

  • Expensive

  • Some instruments very delicate

Listening devices

Listening Devices

  • Advantages

    • Very sensitive to deeply buried victims

    • Can cover large areas and pinpoint location of victims

    • Less sophisticated devices may be used by public works departments

Listening devices1

Listening Devices

  • Disadvantages

    • Usefulness of device diminishes with victims condition

    • Best when ambient noise is low

    • Should be used with hailing method

    • Does not locate all victims

Visual search devices

Visual Search Devices

  • Video and Optical

  • Advantages

    • Provides conclusive verification of victim location

    • Some devices can access openings ¼ inch wide and extend up to 10 feet deep

    • Flexible

    • Doesn’t require verification

Visual search devices1

Visual Search Devices

  • Disadvantages

    • Requires skilled operator

    • Limited field and depth of view

    • Limited reach

    • Does not locate call possible victims

Other search devices

Other Search Devices

  • Thermal sensing devices

    • Can see through smoke but not walls or even heavy dust

  • Infrared and UV sensing devices

    • Sees light radiation

    • Used for covert surveillances – not for US&R

  • Electromagnetic wave detection – Radar

    • Can detect heartbeat and respirations through 10 feet of concrete and steel debris
