Which of the following are the three primary types of firestop systems?

The correct answer identifies the three primary types of firestop systems as penetration firestop systems, joint firestop systems, and perimeter fire containment systems.

Penetration firestop systems are designed to seal openings and joints in fire-resistance-rated walls and floors where pipes, ducts, or cables penetrate, thereby preventing the passage of fire and smoke through these openings.

Joint firestop systems are specifically used to create seals at the joints between building elements, such as walls and floors. These systems play a crucial role in maintaining the integrity of fire-rated assemblies by minimizing the potential spread of flames and hot gases across these joints.

Perimeter fire containment systems are critical in managing the spread of fire and smoke at the perimeter of floor areas in multi-story buildings. They typically involve the use of fire-rated materials to safeguard the edges of floors and ceilings against fire.

Together, these systems are fundamental to effective firestop strategies, ensuring that fire is contained within designated areas and limiting its ability to spread throughout a building. Understanding these primary types enables professionals to implement suitable firestop solutions in accordance with safety regulations and standards.
