Fire emergencies and disasters have claimed lots of lives, property and the environment in the long run.
112 fire incidences have been recorded by the Nyeri Fire Department with 51% occurring in the Nyeri CBD.
Causes of the severe loses include;
Road congestion due to poor town planning
Poor roads
Poor building layout
Inadequate fire fighting facilities e. g fire hydrants, fire extinguishers
Unstrategically placed fire fighting facilities hence not easily accessed.
Poor public awareness on how to immediately respond to such
occurrences. GIS and mapping can address the challenges and reduce the
losses from fire disasters14/09/2015 2
General;- To create a GIS for fire disaster management
planning and emergency response system in Nyeri Municipality
Specific;- To map the existing fire station and external
fire hydrants within Nyeri Municipality. To establish suitable locations for new fire
hydrants and fire stations in Nyeri Municipality.
To determine the optimum route to be used by the various response teams to and from a simulated emergency site.

a) Parameters used in this analysis were nearness to markets, schools, factories, existing fire hydrants, roads and water mains
b) Map showing proposed fire hydrants sites locations
14/09/2015 9
Parameters used were nearness to roads, existing fire stations, market centers, towns , population and slope
Slope analysis was carried out to ensure that the additional fire station sites were placed on areas that have a slope of less than 12%.14/09/2015 10
The additional fire station sites were found to be in Kiganjo town and Mutathiini Sub-location.
a) Fire Stations To Incident Routes b) Closest Fire Station to Incident Route

a) This shows the areas in terms of sub-locations that the respective fire stations can cover in 3 minutes, with the fire engines moving at a maximum speed of 112Km/hr.

b) ArcGIS Online Platform was used in this to show various layers for fire emergency response that were uploaded.
Conclusion
The existing fire stations and existing external fire hydrants have been successfully mapped and a geodatabase of them created.
Analysis of suitable sites of additional fire stations and external fire hydrants was carried out.
Optimum route to be used by various emergency response teams were analyzed and displayed.
Recommendations
Interactive GIS maps should be prepared to enhance real time emergency response.
Records of fire drilling exercises conducted in various areas in Nyeri Municipality should be updated on fire department geodatabase and maps of such shown.
Fire prone areas should also be exhaustively mapped and updated.
External fire hydrants should have proper signage.
