What Is a Fire Rated Door?
The fire rated door is a construction element designed to resist fire during a certain period of time. The fire resistance is determined by a test of an entire doorset comprising of the door leaf(s), frame, hinges, seals, locks and door closer.
Types of Fire Rated Doors
Depending on the characteristics and purposes, fire rated doors can be divided into a variety of categories: steel fire rated doors that are appropriate for offices, factories, warehouses, commercial buildings and other purposes due to their high-quality construction; fire rated glass doors that allow to gain the maximum amount of natural lighting and visibility while protecting in case of fire if properly installed as a complete fire doorset; single and double-leaf fire doors that can be applied in different sites with various opening size requirements; fire rated sliding doors that can be installed in certain commercial and industrial buildings provided a project-specific evaluation has been conducted.
Key Features of Fire Rated Doors
It is vital to ensure the construction and material of a fire doorset is appropriate for its purpose. Fire rated doors should possess high-performance features and be equipped with fire resistant core (in case of steel fire doors), proper seals and hinges, durable frame and reliable hardware. Apart from that, it is crucial to ensure the fire doorset is provided with the appropriate fire rating.
Benefits of Fire Rated Doors
They can prevent the fire from spreading from one zone to another. In addition, they can protect the building's means of egress and facilitate the safe evacuation of people. Moreover, the fire rated doors can be a reliable solution for a wide range of commercial and industrial buildings.
Applications of Fire Rated Doors
Fire rated doors can be applied in hospitals, hotels, offices, shopping malls, schools, factories, warehouses, housing societies and other structures. They are primarily installed in staircases, corridors, switchgear rooms, service rooms and other critical sites and zones requiring separation and smoke containment. Thus, it is vital to choose the right category of fire rated doors considering the special features and requirements of a building.
Important Things to Check Before Buying a Fire Rated Door
While selecting a fire rated door, it is essential to focus on such criteria as fire rating, materials and design, certificates and approvals, size, hardware, and price. There is a wide variety of materials and constructions of fire rated doors; hence, it is essential to pick an appropriate option considering the purpose, number of leaves and other unique requirements. Besides, it is crucial to pay attention to the certificates and approvals provided by a manufacturer and check the accompanying documentation. The size of a door is another vital criterion which should be considered in accordance with the size of an opening and a specific project. Additionally, it is essential to evaluate the quality of hardware (hinges, locks, seals, door closer). The last criterion is the price: it is vital not to compromise on the quality of a fire doorset.
Safety Standards and Requirements
All fire rated doors in India should meet the applicable statutory and regulatory requirements of a specific project. According to the National Building Code and the concerned Fire Authority, the Indian Standard IS 3614:2021 governs the requirements for fire doors and door sets. In order to ensure the required level of safety, it is essential to examine the fire rating of a door and check all the necessary certificates and approvals provided by a manufacturer.
Maintenance and Best Practices
This is important to perform a visual inspection of a fire rated door regularly in order to ensure it is operational. It is vital to check all hardware and seals for any damages or deformation. The clear opening of a doorway should not be obstructed in order to ensure a fast and safe evacuation in case of fire. In addition, never keep a fire door open unless it is a door with an automatic closing mechanism certified to resist fire for the required period of time. It is essential to avoid any unauthorized works or interventions that could compromise the fire protection performance of a door.
Common Mistakes to Avoid
When choosing a fire rated door, many buyers make common mistakes that may result in the failure of a door to protect a building in case of fire. The most common mistakes are: buying a door with unproven fire rating and without proper certification; paying attention to the aesthetic appeal and price rather than functional performance and fire protection; improper installation; not following the maintenance schedule; and unauthorized modifications.
