The dataset describes multiple observations for each 911 phone call that requires San Francisco Fire Department assistance. Each row contains information describing a particular emergency response to an unexpected or dangerous occurrence. Information included are: call type, time, location, neighborhood, response unit, etc.

Fire Calls-For-Service includes all fire units responses to calls. Each record includes the call number, incident number, address, unit identifier, call type, and disposition. All relevant time intervals are also included. Because this dataset is based on responses, and since most calls involved multiple units, there are multiple records for each call number. Addresses are associated with a block number, intersection or call box, not a specific address.
