“Fire stopping is a crucial passive fire protection measure used in buildings to prevent the spread of fire and smoke through openings or joints in fire-resistant walls, floors, and ceilings. Large projects, such as high-rise buildings or commercial complexes, require comprehensive fire stopping solutions to enhance fire safety and comply with building codes and regulations.
Fire stopping works by sealing or filling gaps and openings in fire-rated walls, floors, and other building elements. These gaps can occur due to the installation of various building services, such as electrical conduits, plumbing pipes, HVAC ducts, communication cables, and other penetrations. If these penetrations are not appropriately sealed, fire and smoke can pass through, compromising the integrity of the fire-resistant barriers and allowing the fire to spread rapidly.
Here’s how fire stopping works on building services in large projects:
Identifying penetrations: During the construction phase, contractors and fire safety experts identify all the openings and penetrations where building services pass through fire-rated barriers.
Fire-rated products selection: Fire stop systems typically consist of fire-resistant materials such as fire-rated sealants, firestop putty, firestop pillows, firestop collars, firestop boards, and other specialized devices. These materials are selected based on their fire resistance rating and suitability for specific penetrations.
Installation: Trained and certified fire stop installers or contractors apply the appropriate fire stop products to seal the gaps around the building services, ensuring they are securely protected against the spread of fire and smoke.
Testing and certification: Fire stopping systems usually undergo rigorous testing to ensure their effectiveness in containing fires. Various standards and certifications, such as those from organizations like Underwriters Laboratories (UL) or the International Firestop Council (IFC), are used to verify the performance of fire stop products.
Regular maintenance and inspection: After installation, regular maintenance and inspection of the fire stop systems are crucial to ensure their integrity over time. As buildings undergo modifications and renovations, it is essential to re-evaluate and update the fire stopping measures to maintain their effectiveness.
Properly implemented fire stopping in large projects enhances the building’s overall fire safety by compartmentalizing fire and smoke, giving occupants more time to evacuate safely and providing firefighters with better opportunities to control the fire’s spread. It also helps buildings comply with fire safety regulations and codes, reducing potential liabilities for the owners and stakeholders.”
