Yes, internal fire doors generally need to be self-closing. This is because self-closing mechanisms ensure that the doors automatically close after being opened, thus helping to contain the spread of fire and smoke within a building to protect occupants and property.
So let’s look at the request more closely
Yes, internal fire doors generally need to be self-closing. This is because self-closing mechanisms play a crucial role in fire safety within buildings. When a fire breaks out, these mechanisms ensure that the doors automatically close after being opened, helping to contain the spread of fire and smoke. This not only protects the occupants of the building but also helps prevent the fire from spreading to other areas, potentially saving lives and minimizing property damage.
Self-closing fire doors are designed with special mechanisms that enable them to close automatically once they are opened and released. One common mechanism used is a door closer, which is typically installed at the top of the door and controls its closing speed and strength. The functionality of these mechanisms is vital as they ensure that the fire doors remain closed, even if someone forgets to close them manually.
The use of self-closing fire doors is regulated by various building codes and fire safety regulations worldwide. For example, in many countries, the installation of self-closing fire doors is required in commercial buildings, public spaces, and residential properties. These regulations are in place to ensure the safety of occupants and to meet the necessary fire safety standards.
Failing to install self-closing mechanisms on fire doors can have severe consequences. Without these mechanisms, fire doors may be left open, allowing fire and smoke to spread rapidly throughout a building. This can hinder evacuation efforts and increase the risk of injuries or fatalities. Additionally, it may also result in the fire spreading to adjacent areas, causing significant damage to property.
To highlight the importance of self-closing fire doors, Albert Einstein once said, “In the middle of difficulty lies opportunity.” This quote signifies that amidst challenging situations, there is an opportunity to take action and make a positive change. In the case of fire safety, installing self-closing fire doors presents an opportunity to protect lives and property from the devastating effects of fire.
Interesting facts about fire doors and their self-closing mechanisms:
- Self-closing mechanisms for fire doors can be mechanical or hydraulic, providing different types of closing strengths and speeds.
- Fire doors are typically made of fire-resistant materials, such as steel or other composite materials, to prevent the spread of fire.
- Some self-closing mechanisms use electromagnetic devices to hold the door open temporarily, releasing it once triggered by a fire alarm or smoke detection system.
- Fire doors equipped with self-closing mechanisms are commonly used in high-rise buildings, hospitals, schools, and industrial facilities.
- The effectiveness of self-closing fire doors is often tested and certified by independent organizations to ensure compliance with fire safety standards.
Table: Comparison between mechanical and hydraulic self-closing mechanisms
| Mechanism Type | Benefits | Limitations |
|---|---|---|
| Mechanical | – Simple and cost-effective | – Limited adjustability of closing speed |
| Self-Closing | – Provide reliable closing | – May require more force to open the door |
| Mechanism | action | |
| —————— | —————————- | ——————————————— |
| Hydraulic | – Adjustable closing speed | – More complex installation and maintenance |
| Self-Closing | – Smooth and controlled | requirements |
| Mechanism | closing action | |

In conclusion, self-closing mechanisms are essential for internal fire doors as they aid in containing the spread of fire and smoke, protecting lives and property. Building regulations and fire safety standards emphasize the importance of installing self-closing fire doors. By ensuring these mechanisms are in place, we can effectively enhance fire safety and reduce the risk of fire-related tragedies. Remember, as Franklin D. Roosevelt famously said, “We cannot always build the future for our youth, but we can build our youth for the future.” Therefore, let us prioritize fire safety and implement necessary measures, such as self-closing fire doors, to build a safer future for all.
Video response to your question
This video provides a step-by-step guide on how to adjust a self-closing door hinge. The presenter demonstrates removing and reinserting the hinge pin, adjusting the tension, and testing the door’s closing strength. They also suggest making further adjustments by moving the hinge pins as needed. The presenter emphasizes the importance of properly inserting the pin to prevent it from sliding out. The specific placement of the hinges may vary, but the presenter suggests adjusting them from either the top or bottom.

In ‘residential’ type buildings (care homes, hotels, student accommodation etc.), all fire doors should be fitted with a self-closing device, other than those providing access to cleaner cupboards, plant and other high fire risk spaces and service risers, which should be kept closed and generally locked when not in
In most residential settings, a fire door is legally required to be self closing. This means that they have a fire door closer fitted to the top of the door, to ensure they are closed at all times – which is vitally important in the event of a fire.
The Inquiry recommended (Recommendations 33.29 (a) and (b)) that the owner and manager of every residential building containing separate dwellings carry out an urgent inspection of all fire doors to ensure compliance with current legislative standards and that regular (no less than every three months) checks be carried out to ensure all fire doors are fitted with an effective self-closing device which is in working order.
Most internal fire doors are kept shut at all times thanks to a self-closing mechanism, and even in instances where a fire door needs to be held open, that same functionality is still found.
Closers: Fire rated doors must be self-closing. Either a listed spring hinge or closer is required at all fire rated openings. Hold Open Devices: Mechanical or manual hold open devices are not permitted for use in rated assemblies. Restricting a door from closing negates its ability to perform as a protective barrier.
Closures – Fire doors should always be fully closed and not wedged open – instances of fire doors being held open were found in the Bronx fire in New York in early 2022, and were also reported to contribute to the spread of fire in Grenfell Tower in 2017.
Rule #1 – A fire door must be SELF-CLOSING. I read somewhere recently that the biggest problem with fire doors is that people prop them open or deactivate the door closer. I have no source for this information so consider it hearsay, but I can tell you that I see this ALL the time.
Fire doors are fitted with self-closing devices so that if a fire breaks out, they close and will perform as intended.
All fire doors should have self-closing arms or door closers and clearly marked for an easy exit.
The service door between an attached garage and a house must be self-closing as a protection against fire.
Traditionally fire doors should automatically close, but there are a couple of approved fire door retainers that can be used to keep them open.
All fire doors must have the fixings to self-close, either all the time with a door closer, or via magnetic or similar catches that will release when the fire alarm is sounded.
#0602-2018 requires R-1* and R-2** occupancies to have self-closing doors where doors provide access to interior corridors or stairs. Building owners have until July 31, 2021 to comply with this requirement, and failure to maintain self-closing doors results in a Class C “Immediately Hazardous” violation which must be corrected within 21 days.
