Which rank is NOT part of the ascending order in the San Francisco Fire Department?

The role of Fire Safety Director is not part of the hierarchical structure or ranks within the San Francisco Fire Department. Instead, it is a specific position that focuses on fire safety and emergency preparedness within a building or facility, ensuring compliance with safety regulations and procedures. The ranks included in the ascending order, such as Chief of Department, Battalion Chief, and Assistant Chief, represent traditional leadership roles within the fire department, involving command, strategic planning, and operational management. These ranks define a clear chain of command necessary for effective fire service operations, while the Fire Safety Director role exists outside this chain, emphasizing safety oversight rather than direct departmental rank or command structure.
