Basic Life Support (BLS) and Fire Response Time Exclusions:
Response times calculations do not include incidents that are handled at the fire station (i.e. "walk-ins"), and do not include incidents where the response time is over 12 minutes.

Advanced Life Support (ALS) Response Time Exclusions:
Response times calculations do not include incidents that are handled at the fire station (i.e. "walk-ins"), and do not include incidents where the response time is over 15 minutes.

Excluding these records gives a more accurate picture of how long it takes a company to leave the station and arrive at the emergency.  Both situations - walk-ins and response times of over 12 minutes, or 15 minutes in the case of ALS, make up less than 2% of all responses.
