Fire safety is a critical aspect of any building’s design and maintenance in India. Among the various fire safety measures, the proper installation of fire doors is hugely important. These specialized doors act as barriers against the spread of fire and smoke, giving occupants much-needed time to evacuate. Understanding how long fire doors last, their different ratings, and the norms governing them in India is vital for ensuring that your building has the correct fire safety measures in place. In this article, our experts will talk you through everything you need to know about fire doors according to Indian norms so you can make an informed decision when it comes to your premises.

What Are the Different Fire Door Ratings?

In India, fire doors are classified based on their ability to withstand fire for a specific duration of time. They are rated as follows:

  • FD30: Provides 30 minutes of fire resistance
  • FD60: Provides 60 minutes of fire resistance
  • FD90: Provides 90 minutes of fire resistance
  • FD120: Provides 120 minutes of fire resistance

Each rating indicates the length of time the door can contain a fire and smoke, preventing it from spreading to other areas. These ratings play an important role in determining which fire doors are most suitable for different buildings, taking into account any potential fire hazards and the time required for occupants to exit safely.

Indian Standards for Fire Doors

In India, fire doors must comply with the Bureau of Indian Standards (BIS) specifications. The relevant standards include:

  • IS 3614-1: Specification for fire check doors, Part 1: Methods of test.
  • IS 3614-2: Specification for fire check doors, Part 2: Details of construction.

These standards provide guidelines on the construction, performance, and testing of fire doors to ensure they meet the necessary fire resistance requirements.

What Is the Importance of Fire Doors?

The importance of fire doors cannot be emphasized enough, as they play a vital role in fire safety strategies. In the event of a fire, the main objective is to protect the property and the lives of those inside. Fire doors serve this purpose in various types of buildings, including shops, offices, schools, and factories.

Fire Doors in Commercial and Educational Settings

In offices, schools, hotels, and other commercial settings, fire doors are strategically placed to create fire-resistant compartments throughout the building. This helps to prevent the fire from spreading, giving occupants sufficient time to evacuate.

Fire Doors in Industrial Facilities

Industrial environments often deal with higher fire risks due to the hazardous materials and processes they encounter regularly. Fire doors with higher ratings, such as FD90 or FD120, are commonly used in such settings to provide extended protection, allowing more time for emergency services to arrive.

Monitoring and Maintenance of Fire Doors

Over time, general wear and tear and improper maintenance can cause the condition of the fire doors to deteriorate. To ensure their continued effectiveness and protection, regular inspections and maintenance are essential so fire doors remain fully functional and comply with safety standards.

Replacement of Fire Doors

Timely replacement of fire doors is also essential if they are damaged beyond repair, do not close properly, or fail to meet safety regulations during inspections. It’s also worth bearing in mind that renovations or updates in fire safety regulations might lead to the installation of new fire doors or the upgrading of existing ones.


By understanding the importance of fire doors, their ratings, and the necessity for regular maintenance and timely replacement according to Indian norms, you can ensure that your building remains safe and compliant with fire safety regulations. This not only protects your property but also ensures the safety of all occupants in the event of a fire.
