Approximately 80 volunteers work alongside career firefighters to provide emergency medical, fire and rescue services to Fairfax City and the immediate surrounding areas, including George Mason University.

Potential members have to move through four statuses before being recognized as a full member of the fire force: recognized, probationary, full and life. All candidates must complete orientation training, pass a physical exam, ride along with professional firefighters, finish firefighter or EMS qualification training, and complete 40 hours of training every year.

Additional auxiliary volunteers are needed for fundraising efforts and staffing events, like fire station bingo.
