It shall be the policy of the WestCom Emergency Communications Center to adhere to the Medical Priority Dispatch System when utilizing EMS resources in response to medical calls for service.




3.1 Requests for medical service(s) will be interrogated as outlined in SOP #602, Fire Incident Interrogation.  


3.2 An EMS response shall also be initiated anytime a qualified requesting party determines the need for an ambulance response, regardless of whether detailed patient information can be provided.  Qualified requesting parties would be police officers, firefighters or EMT’s from WestCom agencies or surrounding agencies.  This does not include staff members from health care clinics or doctor’s offices.  With any request for EMS services, the responsible fire department should be dispatched along with the ambulance unless the request meets the criteria for “Ambulance Only Dispatch”.


3.3 EMS units are recommended by the CAD system any time an incident is entered using the proper type code.


3.4 EMS units will be dispatched, monitored and have pertinent times recorded using the same procedures established for fire units as outlined in SOP #603, Fire Dispatching Procedures.


3.5 Requests for an Additional Ambulance Unit:


Additional ambulance units may be requested by EMS, fire or police personnel.  Upon receipt of such a request, the next due ambulance unit will be dispatched and the on scene commander notified with information.


3.6 Self Initiated Responses:


EMS may respond on a still alarm.  An incident may be reported directly to EMS quarters or a walk-in patient may have arrived at the EMS quarters.  The dispatcher shall create an incident, ensuring the address is verified through the CAD system.  


3.7 Chief Officer Notifications:


The Fire / EMS Supervisor(s) or equivalent will be contacted and advised anytime the following situations occur:


3.7.1 Any Multiple Casualty Incident (MCI).
