When is Fire Stopping Required?

In an era where fire safety and building codes have become increasingly stringent, ensuring the protection of life and property from the devastating effects of fires has taken centre stage. Among the various measures employed to prevent the spread of flames, smoke, and toxic gases within buildings, fire-stopping stands as a crucial defence mechanism. In this article, we’re going to find out when fire-stopping is required and why it’s so important.

Firstly, Why is Fire Stopping Required?


Fire stopping is a crucial aspect of building safety and plays a significant role in preventing the spread of fire within a structure. It involves the use of various materials and techniques to seal gaps and openings in fire-rated assemblies, ensuring that fire, smoke, and toxic gases cannot pass through. By creating effective fire barriers, fire stopping helps to contain fires within specific areas, giving occupants more time to evacuate and allowing firefighters to tackle the blaze more effectively.


Instances Where Fire Stopping is Required


There are several instances where fire stopping is required to meet building codes and regulations. These instances include:


Membrane Penetrations


Membrane penetrations occur when pipes, cables, conduits, or other services pass through fire-rated walls or floors. These penetrations create openings that can potentially compromise the fire resistance of the assembly. Fire stopping is necessary to seal these penetrations using fire-resistant materials, such as intumescent sealants or collars, to maintain the integrity of the fire-rated barrier.


Through Penetrations


Through penetrations refer to openings that allow the passage of pipes, ducts, or electrical conduits that penetrate fire-rated walls, floors, or ceilings. These penetrations can create pathways for fire and smoke to spread between compartments. Fire stopping is required to seal these penetrations with appropriate fire-rated materials, such as fire-rated putty, fire-resistant foam, or firestop collars, to prevent the spread of fire and smoke.


Blank Openings


Blank openings are spaces left intentionally or unintentionally in fire-rated walls or floors during construction or renovation. These openings can compromise the fire resistance of the structure, allowing the rapid spread of fire and smoke. Fire stopping is essential to seal these blank openings using fire-rated materials, such as fire-rated boards, mineral wool, or firestop caulks, to restore the fire resistance of the assembly.


Fire-Rated Construction Joints


Fire-rated construction joints are areas where two or more fire-rated assemblies meet, such as the junction between walls and floors or walls and ceilings. These joints can create vulnerabilities in the fire resistance of the building if not properly sealed. Fire stopping ensures these joints are adequately protected using fire-rated sealants, fire-resistant gaskets, or firestop pillows to maintain the integrity of the fire barriers.


Perimeter Containments


Perimeter containments are external walls or facades of a building that may require fire stopping to prevent the spread of fire from one compartment to another. These containments are crucial in high-rise buildings or structures located close to each other. Fire stopping measures, such as fire-rated cladding systems, fire-resistant barriers, or firestop coatings, are employed to enhance the fire resistance of these exteriors and inhibit the vertical or horizontal spread of fire.


Professional Fire Stopping Installation & Maintenance


Given the critical role fire stopping plays in protecting lives and property, it is crucial to ensure that fire stopping installations and maintenance are carried out by qualified professionals. Improperly installed or poorly maintained fire stopping systems can render them ineffective, compromising the overall fire safety of a building.


Companies, like ourselves here at Ark Fire Protection, specialise in professional fire stopping services, providing expertise in fire barrier installations, inspections, and maintenance. Our engineers are well-versed in local building codes and regulations and have the knowledge and experience to identify potential fire stopping deficiencies and rectify them effectively.


During the installation process, skilled technicians employ industry-approved methods to seal penetrations, close blank openings, and reinforce construction joints. They use high-quality fire-rated materials and follow manufacturer guidelines to achieve reliable and long-lasting fire barriers.


Regular Maintenance and Inspections


Regular maintenance and inspections are equally crucial to ensure ongoing fire safety. Ark Fire Protection provides scheduled maintenance programs to assess the condition of fire barriers, identify any signs of damage or deterioration, and promptly address them. This proactive approach helps prevent potential fire hazards and ensures that fire stopping systems remain in optimal working condition.


In addition to installation and maintenance, professional fire stopping services also offer consulting and compliance assistance. They stay updated with the latest building codes and regulations, providing guidance to building owners and managers on how to meet the required fire safety standards.


In Summary


Fire stopping is an essential aspect of building safety, aiming to prevent the spread of fire, smoke, and toxic gases. Employing professional fire stopping services ensures that installations are carried out correctly, and regular maintenance is performed to uphold the effectiveness of fire barriers.
