According to the International Fire Code (IFC) 2021, when specific fire safety requirements are not explicitly provided for in the code, the responsibility to determine the applicable requirements falls upon the Fire Code Official.

Reference from the IFC (2021):

IFC Section 104.1 – General Authority and Responsibilities:

This section explicitly grants the Fire Code Official the authority to interpret the code and determine the necessary safety measures in cases where the code does not provide specific guidance.

It states: "The fire code official is hereby authorized to enforce the provisions of this code and shall have the authority to render interpretations of the code and to adopt policies and procedures in order to clarify the application of its provisions."

IFC Section 104.9 – Alternative Materials and Methods:

This section further supports the authority of the Fire Code Official by allowing them to approve alternative fire safety measures when strict compliance with the code is not feasible.

Why Other Options Are Incorrect?

A. City Manager:

The city manager is responsible for administrative and operational management but does not have the authority to interpret or enforce fire code requirements.

B. Legal Counsel:

Legal counsel provides legal advice but does not have jurisdiction over fire safety code enforcement.

C. Board of Appeals:

The board of appeals reviews disputes and interpretations made by the Fire Code Official, but they do not have primary responsibility for determining applicable fire safety requirements.

Final Conclusion:

The Fire Code Official is the designated authority responsible for interpreting and applying fire safety requirements in situations where the International Fire Code (IFC) does not explicitly provide specific provisions.
