For high-traffic openings, firestop materials should generally be re-enterable. This characteristic is essential because high-traffic areas often require frequent access for maintenance, upgrades, or other modifications. Re-enterable materials allow for effective sealing against fire, smoke, and other hazards while also enabling future alterations without compromising the fire-resistive properties of the installation.

When firestop systems are designed to be re-enterable, they can accommodate changes in the infrastructure without needing a complete replacement, ensuring ongoing safety and compliance with fire codes. This flexibility is crucial for systems in buildings that are subject to continuous change or have high usage, allowing both safety and practicality to be maintained.
