What should be verified during the installation of a firestop system?

Verifying the correct materials during the installation of a firestop system is crucial for ensuring the system's effectiveness. Firestop systems are designed to prevent the spread of fire, smoke, and toxic gases through penetrations and openings in fire-resistance-rated walls and floors. The materials used must meet specific standards and certifications that align with the fire rating requirements of the construction.

Using the wrong materials can compromise the integrity of the firestop, leading to potential failure in a fire situation. For instance, materials need to be specifically rated for the type of construction and the particular installation scenario, as some materials may not have the necessary fire-resistance characteristics. Thus, confirming that the correct materials are used protects the safety of the building and its occupants.

The other aspects—such as installation speed, cost, and appearance—while important for different reasons, do not directly impact the firestop system's ability to perform its critical function of fire containment.
