Fire doors must be used in walls which form the compartmentation of the premises – specific areas within the building that are constructed to be fire-resistant. These may be individual rooms, but could also contain multiple rooms or might be vertical risers and lift shafts.
First, the codes aim to provide life safety, ensuring occupants have a safe path of egress in the event of a fire. As such, fire-rated doors are commonly found at points of egress to create evacuation pathways through entrances, exits, lobbies and stairwells.
A fire door is always required in buildings other than dwellings, such as offices, factories, etc. In these cases, access to protected corridors which are used as a means of escape must be protected from fire by the use of fire doors.
Do I need a fire-rated door HDB? Fire-rated main doors are provided where required under the Fire Code, such as the units where the main doors are within 3 meters of the lift lobby or staircase. If your HDB is located within 3 meters of the lift lobby or staircase then you need a 30 minutes fire-rated door.
Fire-rated doors, or doors that are made to withstand heat, smoke and fire, are required for many commercial buildings. Beyond that requirement, a business may want to invest in fire-rated doors for the safety of everyone and the protection of property.
However, building regulations do not state that a kitchen door needs to be a fire door. That said, many households prefer to install a fire door leading to the kitchen to provide a greater degree of protection against fires.
Doors leading from the property into the garage must be fire doors for safety reasons, protecting the entire property should a fire erupt in the garage. Other areas to consider installing fire doors are kitchens, downstairs landings/hallways and utility rooms.
The IRC requires the door between the house and the attached garage to be a minimum of 1 3/8 inches thick – either a solid wood door, a solid or honeycomb-core steel door, or a 20-minute fire door.
Staircases are escape routes as well, and usually all rooms need a 30-minute separation – in other words fire doors – around them on the ground floor. The only way an escape route could lead through a kitchen is if you have a mist system installed, or sprinklers.
If you manage a property, it's important to get the right sprinkler system in place, though you will also need to consider fire alarms, fire doors and signage. There are also special sprinkler systems available for vulnerable or older people - find out more on the sprinklers for carers and social workers page.
b) NFPA 80 – Fire door assemblies (doors, frames and hardware) are designed and tested to withstand smoke, flames and hot gases during a fire. The standard that addresses the requirements for fire door assemblies in depth is NFPA 80 – Standard for Fire Doors and Other Opening Protectives.
Shaft enclosures must have 90-minute doors for a 2-hour wall, and 60-minute doors for a 1-hour wall. Fire barriers and fire partitions that are rated for 1 hour or 1/2 hour may have 45-minute or 20-minute fire door assemblies, depending on where the walls are located within a building.
however, it is generally accepted that a bathroom/cloakroom poses a low fire risk and therefore the door need not be a fire door.
Any new build or home renovation that has three or more floors must have fire doors fitted to every habitable room that leads from a stairwell. This applies to loft conversions where an extra floor has been added to a two-storey home. Any door leading from your home into an integral garage must be a fire door.
Rooms housing transfer switches, transformers, panelboards, and switchboards associated with an emergency system require a 2-hour fire rating unless the room is fully protected by an approved automatic fire protection system. NFPA 70-2023 (National Electrical Code) section 700.10(D)(3)
Garages shall be served by at least one side-hinged door not less than 2 feet 6 inches (760 mm) in width and 6 feet 8 inches (2032 mm) in height.
Any domestic dwelling that is three storeys high or over must have fire doors installed. All doors between habitable rooms and stairwells must be fire doors. If there is an internal garage or a converted loft, these areas also need to have fire doors installed as entryways to the house.
Fire doors are required to be fitted with either a jamb closer or an overhead door closer: The door, frame and furniture together must be capable of providing • a minimum of 30 minutes fire and smoke resistance. The door needs to be fitted with special plastic seals that swell up with heat, called intumescent strips.
Other than the entry into the attached garage door, you're likely required to install fire-rated doors in multi-story houses with rooms that connect to the stairwell. Again, check your local building codes so you won't have to correct any mistakes.
Muddy footprints, paw prints and piles of dirty clothes are not what your kitchen is for. That's why any utility room you build should (wherever possible) feature an external door. Then, when your kids, or whoever else for that matter, come traipsing in they can take off their dirty clothes, shoes, etc.
If it is a new clean utility room, then it must be 1-hour fire-rated and be protected with sprinklers.
For those occupancies with capacities of 50 or more people, two separate and remote exits are required. Exit doors must open outward with the path of travel and door openings shall have a minimum of 32 inches in clear width. Emergency lights are required to illuminate the path of egress.
Fire doors are designed to stop the spread of both: flames and smoke. Fire-rated doors help slow or prevent the spread of both fire and smoke, but they are not designed to be completely fireproof. These doors will eventually burn through in a fire.
