Passive Fire Protection FAQs

Fire Doors

The use of fire door assemblies within buildings is regulated by the National Construction Code of Australia which references the Australian Standard AS1905.1: 2005.

This standard outlines requirements for fire doors, including the type and size of door required for each application.

It also outlines testing requirements for fire doors, including both destructive and non-destructive testing (NDT).

For example, the AS1905.1: 2005 states that all fire doors must be tested to ensure they meet the requirements set out in this standard.

The standard states that if a door fails a test then it must be repaired or replaced before it can be used again.

Fire doors are important because they keep fire or smoke in the room or ‘compartment’ in which it started. They stop it from spreading to other areas of the building. Fire doors are an integral part of any building’s passive fire protection system.

They are designed to be strong and durable enough to withstand high temperatures, to prevent flames and smoke from entering other areas of the building. This means that if a fire starts in one area, it won’t spread through the entire building unless there are gaps in the fire door system.

The most common type of fire door is made from solid timber panels with a metal frame, but there are also other types including glass and metal doors which can be used to provide more visibility into a room while still meeting safety requirements.

Fire doors are a crucial part of any building’s fire safety system. They provide an important barrier between the interior and exterior of a building, helping to prevent the spread of fire and smoke.

Fire doors are usually thicker than a standard door and most have a solid core of variable material. The construction of fire doors varies depending on the manufacturer. But, the critical part is that it is tested and certified to withstand fire for at least 30 minutes. Manufacturers must have the design of their fire doors and frames tested together as a set at an approved fire door testing centre. Then they must be considered for certification. When certification is approved, every fire door set constructed to the same design specifications by that manufacturer will be fixed with a label. The label identifies the manufacturer, date of manufacture and fire rating. This label can usually be found on the top edge of the door.

Fire doors are not fireproof. They’re fire-resistant. Fire doors are designed to delay a fire in breaking through from anything from 30 minutes to hours and hours, allowing firefighters to reach the location.

Class 1 fire doors can withstand temperatures of up to 1200°C for at least 30 minutes before they begin to give way. Class 2 can withstand temperatures of up to 600°C for at least one hour, and Class 3 can resist temperatures of up to 450°C for at least two hours.

Fire doors aren’t completely impenetrable—they have been known to fail under the pressure of an intense blaze—but they do provide an extra layer of protection between you and the flames outside.

Fire doors are designed to keep the heat and smoke from a fire contained to one area of a building. Fire doors and their frames are usually tested to hold back fire for 30 minutes or 60 minutes. This means that even if there’s a serious blaze in your building, the fire door will keep it from spreading. The ability of your fire door to withstand fire is dependent on it being properly installed with the correct seals and fire rated hardware including fire door closers.

The condition of your fire door, especially one that’s in regular use could deteriorate over time. Check your fire doors regularly and ensure any fire door maintenance is attended to promptly. Fire door inspections can help to identify non-compliant fire doors.

Fire doors can have a rating greater than 60 minutes but these are not required in most situations.

Fire doors are a crucial part of your building’s fire protection system. If your fire door does not close properly, it can compromise the integrity of the entire system and leave you vulnerable to fire damage.

Most fire doors in Australia need to be checked every six months. This includes all types of fire doors, including both manual and automatic doors.

Fire doors are a legal requirement in all non-domestic properties, such as businesses, commercial premises, and public buildings. They are also required in residential flats and houses of multiple occupancy.

Fire doors are designed to prevent the spread of fire between rooms. They can be either manually operated or automatically activated by heat sensors or smoke detectors. Fire doors are made from a variety of materials including metal, wood, glass and plastic. The most common type of fire door is a solid panel door with a self-closing hinge mechanism (known as a “panic bar”) that allows users to exit quickly in an emergency situation without having to open the door manually first.

Fire doors must be fitted with an approved self-closing device if they open into a corridor where there is no other means of escape from the building or room they’re installed within.

The National Construction Code sets out the requirements for fire doors. The purpose of these doors is to stop the spread of fire from one part of a building to another, or from one building to another. Fire doors must be able to resist a temperature rise for at least 30 minutes. They must also be able to withstand the force of a fire hose being used on them for at least 15 minutes (and not break under any circumstances).

Fire doors must be fitted with fire rated hinges, locks and hardware. They are not made out of a special type of paint, and can be painted using regular decorative paint or varnish without damaging their performance.

Avoid using heat or chemical paint strippers if the intumescent seals are in place. Also avoid painting over any hinges, hardware or seals.

Fire doors must be fitted by a competent individual. You should ensure that the person fitting your fire doors has had the relevant training to do so. Whatever the rating of a fire door, if it is badly fitted, it may not withstand a fire for any more than 5 minutes. There are legal requirements and specifications as set out by building regulations governing the installation of fire doors. (see National Construction Code of Australia) The gap between the fire door and frame, for example, should be between 2 and 4mm. These specifications can be difficult to meet unless installation is by someone with experience and joinery skills.

The following are some of the most common mistakes made during installation:

1) Improperly sized hinges – hinges must fit tightly into their mortises without leaving gaps where they meet;

2) Improperly sized lockset – locksets should also be properly fitted;

3) Excessive gap between door and frame – gaps should be no greater than 4mm all around when closed;

4) Lack of self-closing mechanism – this reduces risk of spreading flames from room to room by closing automatically after being opened by occupants in an emergency;

5) Lack of smoke seals at base of door or around bottom edge of glass panels with glass doors

Compartmentation

Fire barriers, firewalls, fire partitions, and smoke barriers are all included in compartmentation. Compartmentation is one of the most effective ways to prevent fires from spreading through a building.

Fire barriers are walls with no openings that separate areas where fires may occur from the rest of the building. Firewalls are similar to fire barriers except they also have a ceiling. Fire partitions are walls that divide rooms and do not have any openings. Smoke barriers are similar to firewalls except they separate areas where there could be smoke from other parts of the building. Smoke barriers may or may not include ceilings.

Compartmentation is important because it helps prevent fires from spreading throughout a building by preventing them from entering other areas through openings in walls, floors, and ceilings.

Fire partitions are a type of fire-resistant wall that is used to separate rooms in a building. Fire-resistant walls are designed to prevent the spread of fire, and they are usually made from metal or concrete. Fire partitions can be made from any number of materials, however, including brick, stone, concrete block, or metal studs.

Fire partitions are typically found in larger buildings, such as warehouses or factories. They are also commonly used in multi-story residential buildings. In some cases, fire partition walls may be required by law for certain types of structures or businesses.

Fire barriers are materials that delay the spread of fire and smoke. Fire barriers are used to separate areas of different fire risks, and they can be used in any application where there is a risk that a fire may spread between two spaces.

Fire barriers are usually made from non-combustible materials such as metal or concrete, which help to prevent fires from spreading by restricting the flow of oxygen and limiting the amount of fuel available to feed the flames. They can also be made from other materials that retard heat transfer, such as mineral wool insulation or gypsum wallboard (drywall).

In addition to preventing fires from spreading, fire barriers also protect people from injury by limiting their exposure to smoke and heat.

Firewalls are designed to be fire-resistant, but they are also designed to sub-divide buildings such that if collapse occurs on one side, this will not affect the other side. They can also be used to eliminate the need for sprinklers, as a trade-off.

A firewall is a wall that divides a building into two or more sections and which is constructed with materials that are capable of withstanding fire for a specified period of time without causing structural collapse. Firewalls may be required by building codes or ordinances, but they are not required by fire code regulations and are often used as an alternative when building codes require sprinklers or smoke alarms in high-rise buildings.

Smoke barriers are designed to prevent smoke from spreading from one room to the next. The idea is to keep smoke from entering your home and getting trapped in the attic or basement, where it can cause serious damage to your property.

Smoke barriers can be made of many different materials, but the most common types include:

-Glass blocks

-Insulated glass panels

-Metal doors with glass panes

Fire-resistant glass is a type of glass that is used in the fabrication of fire-resistance rated windows in walls or fire doors. Fire-resistant glass uses multi-layer intumescent technology or wire mesh embedded within the glass to resist the spread of heat and flames through a window or door. Fire-resistant glass is typically used for applications where there is a potential for exposure to extreme heat, such as in high-rise buildings. It can also be used on doors that are exposed to high heat from an open flame, such as those found in kitchens or laboratories. Fire-resistant glass should not be confused with tempered glass, which is designed to shatter into small pieces when exposed to high temperatures so it does not pose a hazard to occupants.

Fire-resistant glass is typically fabricated with one or more layers of intumescent material sandwiched between two panes of clear or tinted float glass. The intumescent layers expand when exposed to high temperatures, preventing flames from traveling through the glass and into occupied spaces.

Occupancy separations are barriers that separate parts of a building where different uses are on each side. For instance, apartments might be on one side and stores on the other side of an occupancy separation.

Occupancy separations are usually escalator enclosures, elevator shafts, stairways, and fire-rated corridors. They can also include fire walls and smoke barriers. The separation must comply with the NCC as well.

A closure is a firestop device that is used to prevent the spread of fire from one compartment to another. It can be any type of barrier, including fire doors and fire dampers. They are usually installed in walls or ceilings as a permanent solution for separating spaces.

Firestops have been designed to provide different levels of protection. For example, fire barriers provide complete separation between two compartments, while fire partitions are designed for only partial separation. Fire stops are typically categorized according to their location within a building: vertical or horizontal. Vertical fire stops include floor-ceiling assemblies and walls; horizontal fire stops include floors, roofs and exterior walls.

Some building codes identify closures (fire dampers) as being treated identically to closures.

Fire dampers are a type of fire protection device that are used to control the flow of air in a building.

Fire dampers can be installed in a variety of places, including ducts and shafts, as well as at the ends of corridors and stairwells. They help prevent the spread of fire by restricting the flow of air through these spaces.

 

FIRESTOPPING MATERIALS

Fire stopping materials are used to prevent the spread of fire and smoke between floors, walls, and ceiling cavities. There are several different types of fire stop materials, each with its own advantages.

Firestop systems include:

– Foam sealants

– Firestop doors

– Firestop barriers

– Firestopping systems

fire stopping

Cable coating (application of fire retardants, which are either endothermic or intumescent, to reduce flame-spread and smoke development of combustible cable-jacketing) is a process that provides a protective barrier between the combustible insulation and the non-combustible jacket, which reduces the potential for charring and initiates the intumescent reaction. The endothermic reaction occurs when fire retardant chemicals are mixed with water in a hydrolysis reaction. This reaction converts the water into steam, which cools the surrounding air temperature and lowers the combustion rate.

The intumescent reaction involves char formation within the insulation and jacketing materials, which creates an insulating char layer between the fire retardant chemicals and flame source. This char layer serves as an insulator that prevents heat transfer from occurring through both sides of the material without melting. The char layer also forms a barrier against oxygen supply for burning in order to prevent further thermal degradation of cables or wires inside of them (such as PVC insulation).

Structural fire protection guards are essential structural components (such as structural steel and joint systems) from the effects of fire. They provide physical barriers that keep fires from spreading and protect people who may be in danger.

Structural fire protection guards can be made of any material, including metals and plastics. The most common material used is steel, but other materials such as fiberglass are also used. These materials are chosen based on factors such as cost, availability, strength, durability and maintenance requirements.

The spray fireproofing is a thin coating of intumescent or endothermic paints, fibrous or cementitious plasters applied to keep substrates such as structural steel, electrical or mechanical services, valves, liquefied petroleum gas (LPG) vessels, vessel skirts, bulkheads or decks below either 140 °C for electrical items or ca. 500 °C for structural steel elements to maintain operability of the item to be protected.

The main purpose of spray fireproofing is to reduce heat transfer by radiation and convection between the substrate and the surrounding atmosphere. This can be achieved by applying a layer of material with high thermal insulating capacity (for example rockwool). The layer must be thick enough so that it does not burn through before the temperature in the substrate reaches an ignition temperature.

Fireproofing cladding is used in a variety of applications, including on the outside of buildings and ships.

Materials for such cladding include perlite, vermiculite, calcium silicate, gypsum, intumescent epoxy, Durasteel (cellulose-fibre reinforced concrete and punched sheet-metal bonded composite panels), sprayed concrete and sprayed polyurethane foam.

Sprayed concrete is often used for fireproofing purposes because it can be applied quickly and easily over existing surfaces. It does not require any special preparation before application since it hardens within minutes after being applied to the surface. This makes it ideal for use in areas where there are no available surfaces on which to apply other types of fireproofing cladding.

Polyurethane foam is another popular type of fireproofing cladding that can be applied over existing surfaces or directly onto walls or ceilings. It offers excellent thermal insulation properties as well as being very strong and durable when exposed to high temperatures such as those produced by fires.

The fire safety systems in a building are designed to protect the building and its occupants from fire, smoke and other hazards. Fire detection and alarm systems are essential components of these systems.

In order to ensure that a fire alarm system will function properly in the event of a fire, an assessment should be made of the various parts of the system to determine their suitability for use in a fire situation. This would include checking that all cables are rated for use in a fire environment and not subject to degradation when exposed to high temperatures. It is also important that all electrical equipment installed within the building is suitable for use in a potentially flammable environment (e.g., heat-resistant).

Enclosures (boxes or wraps made of fireproofing materials, including fire-resistive wraps and tapes to protect speciality valves and other items deemed to require protection against fire and heat—an analogy for this would be a safe) or the provision of circuit integrity measures to keep electrical cables operational during an accidental fire.

Firestop pillows are passive fire protection items used for firestopping holes to achieve fireproofing. The various kinds of firestop pillows are intended to slow the spread of fire. They are often used to meet fire-resistance ratings in conduits that need frequent access. These systems can be customized to any application, and there are several types available including:

– Drywall firestop pillow: This material is used in new construction or when walls require repair. These pillows prevent smoke and flames from spreading through open spaces by creating a barrier between two different materials.

– Rubberized fiberglass pillow: This type of pillow is made from fiberglass cloth covered with rubber coating. It provides excellent thermal performance, good ductility and high resistance to impact. It is also resistant to corrosion due to its impermeability properties. It can be installed quickly because it does not require any special tools or equipment for installation purposes, making it ideal for emergency situations such as fires or floods where time is limited due to structural damage caused by these events which might result in loss of life if left unchecked!

Passive fire protection provides a vital service in keeping you safe.

Passive fire protection like fire stop products and fire doors are invisible, silent and discreet. However, their very nature is to protect the people and structures from the destructive consequences of a fire. This makes passive fire protection one of the most important components in any facility’s safety efforts.
