Emergency Services & GIS

• Increased adoption of geospatial technologies by emergency services

• Highlights of various applications of GIS

Fire Literature

• 1710: 4.1.2.1 time objectives for call response

• 1710: 4.1.2.2-3 explanation of standard language– 90% of calls within 6 minute response

• 1 minute dispatch time (Alarm Processing)• 1 minute turnout time EMS, 80 seconds fire• 4 minute drive time

Fire Literature

• Fire Protection Handbook 20th edition volume 2 section 12 chapter 13: GIS for fire station locations and response protocols (AKA ESRI white paper)– Incident analysis– Travel time modeling– Importance of response time fire & EMS– Fire department total reflex time sequence

dispatch time, turnout time, response time, access time & setup time

– Reducing response times

Hot Spot Analysis

Measuring DistanceEuclidean Network

Response Times

• Calculate existing service areas

• Percent of coverage– Township 16.3 mi2

– 4 min 8.5 mi2 52%– 6 min 14.3 mi2 88%– 8 min 16 mi2 98%

ERZ Border Validation

• ERZ = emergency response zone

• Investigate border placement based on current assignment & response time

• Bright pink area (as determined by model) that needs closer examination

Fire Station Site Selection

• Specific aspects must be taken into consideration when selecting a location for a fire station site vs. situation– Response times– Historical call density/target hazards– Zoning/land use– Parcel size/topography– Projected population growth/zoning

Site Suitability Analysis

GeoWorld August 2009 - Beyond Mapping: Spatial Sensitivity Analysis Assesses Model Response

Site Suitability Analysis

• Site Suitability based on– Call density 40%– Population density 40%– Zoning 20%

• Run time model based on sites recommended with high suitability

Mutual Aid Necessity

POSITION ASSIGNMENT STAFFINGIncident Commander Coordinates all on scene operations

(Company Officers run command until ranking officer arrives) second serves as safety

2

Pump Operator Maintains water flow to attack crews and radio communications(For safety requirements can not be counted for backup)

2

Ventilation Removes heat, toxic gases and smoke improving victim survivability and safer environment for fire crews.

2

Primary Search Rapid discovery and removal from toxic environment insures highest possible chance for victim survivability without brain damage.

4

Fire Attack Two 1 ¾” Lines @ 125 gpm each for adequate water flow

4

EMS Renders immediate medical care torescued victims or injured firefighters

4

SUB TOTAL 18Rapid Intervention Team

(Rescues trapped/injured/lost firefighters) 4*

TOTAL 22

• Required number of tasks on the fire ground

• Necessity for certain apparatus types

• Specialty skills• Sequential vs.
