The penetration may or may not contain a firestop system. An F rating shall be based upon flame occurrence on the unexposed surface, while the T rating shall be based upon the temperature rise as well as flame occurrence on the unexposed side of the firestop system. Penetration firestopping systems and fire resistive joint systems are a passive means of fire protection. It also helps track the status of firestop installations and generate reports with critical firestop system and contractor status information. Firestops prevent unprotected horizontal and vertical penetrations in a fire-resistance- rated wall or floor assemblies, which can diminish the fire-resistance ratings of these structures and are the leading cause of rapid and erratic spreading of smoke and fire.

The biggest issue with these systems is that they are proprietary to each manufacturer, but large facilities tend to have firetop systems by a number of different manufacturers. It also helps track the status of firestop installations and generate reports with critical firestop system and contractor status information.
