The internal customer base for a fire and emergency service organization is made up of employees and members of the organization; the external customer base is composed of:

• A. 70 percent volunteer and 30 percent career firefighters
• B. Apparatus, equipment, and supply manufacturers and suppliers
• C. Centralized and decentralized fire and emergency services organizations
• D. Members of the general population within the service area who are beneficiaries of the services provided

Answer: (D)

The fundamental idea here is who the fire department serves outside of its own staff. Internal customers are the people who work for or with the department, while external customers are those who benefit from its services.

External customers are the members of the general population living or working in the service area who rely on the department’s work—people who are beneficiaries of fire suppression, rescue, medical responses, prevention efforts, and safety education. This makes the general population within the service area the correct external customer group.

The other options don’t fit the concept of customers: staffing mix talks about who makes up the workforce, vendors are suppliers, and organizational structure describes how the agency is organized rather than who it serves.
