Which code often governs firestop installations in the US?

The International Building Code (IBC) is often the governing document for firestop installations in the United States. The IBC establishes comprehensive regulations for building safety and addresses various aspects of construction, including fire safety measures. Firestop systems are critical for containing fire and smoke within a building, and they must comply with the structural and safety requirements outlined in the IBC. This code provides specific guidelines regarding the materials, methods, and installation practices that must be followed to ensure that firestop systems are effective and compliant with safety standards.

While other codes like the National Fire Protection Association (NFPA) documents and the International Fire Code (IFC) also provide important information related to fire safety, the IBC is specifically focused on the construction and design of buildings, making it the primary reference for firestop installations.
