Abbreviation for Fire Hose Reel

This includes all of the non-service elements of a building such as the roof, walls, glazing and floor, that impact upon the building’s thermal performance. The fabric may impact upon a building’s thermal performance through its insulating ability, or through its thermal inertia or thermal capacitance, which is the ability to slow energy flow and so delay or reduce the transfer of heat.

Fall Prevention                                          

  • Anchorage - An anchorage point for a fall injury prevention system. It is the means for attaching a lanyard, lifeline or other components to a secure point.
  • Arrest Force - The force imposed upon the worker and the anchorage point, the moment the fall-arrest system stops the fall, measured in kilonewtons (kN).
  • Body Containment Devices - Designed to contain the body of a falling worker and to distribute forces resulting from an arrested fall to minimise the likelihood of injury. They consist of a full body harness (parachute type) together with associated components such as a lanyard and personal energy absorber. Harnesses can be used for restraint systems and work positioning systems according to relevant sections in AS/NZS 1891.1 and AS/NSZ 1891.4.
  • Droplines - Vertical lifelines.
  • Double or Triple Action Device - A self-closing hook or karabiner with a keeper latch which will automatically close and remain closed until manually opened. These units have a minimum of at least two distinct and deliberate consecutive actions to manually open them.
  • Fall-Arrest System - An assembly of interconnected components comprising a harness connected to an anchorage point or anchorage system, either directly or by means of a lanyard, lanyard assembly or pole strap, and whose purpose is to arrest a fall in accordance with the principles and requirements of AS/NZS 1891.4.
  • Fall-Restraint System - A system of anchors, static lines, guard rails etc, designed to prevent a person from reaching the position where a fall may be possible.
  • Fall-Arrest Devices - There are three types:
    Type 1 fall-arrester device (includes rope and rail grabs) – this is a fall-arrest device that travels along an anchorage line and, when loaded, locks to the line. The user is connected via a short lanyard to the activating lever, which locks the device in the event of a fall. A typical use of a Type 1 device is as a ladder fall-arrest system, using a rigid rail or a flexible line attached to the ladder.
    Type 2 and Type 3 fall-arrest device (also known as an inertia reel or self-retracting lifeline) – this is a fall-arrest device from which a spring loaded anchorage line pays out, and which locks when loaded and releases when the load is removed. When incorporating a retrieval winch, it becomes a Type 3 fall-arrest device.
  • Fall Indicator - A visual indicator that shows that the fall-arrest system or device has been used to arrest a fall.
  • Fall Injury Prevention System - A system designed to arrest a person’s fall from one level at a workplace to another and minimise the risk of injury or harm to a person who falls from one level at a workplace to another.
  • Free Fall - Any fall or part of a fall where the person suffering the fall is under the unrestrained influence of gravity over any fall distance, either vertically or on a slope on which it is not possible to walk without the assistance of a handrail or hand line. The maximum allowed free fall is 2 metres.
  • Inertia Reel (also known as a self-retracting lanyard or fall-arrest block) - A mechanical device that arrests a fall by locking onto a dropline and at the same time allows freedom of movement.
  • Job Safety Analysis (JSA) - These are a means of setting out the ways that hazards associated with a task will be managed on a site and the work methods that will be used. They are usually a standardised form produced by an association, employer or State Government agency. Refer to Appendix 4.
  • Karabiners - These are metal types of connectors that can be attached to anchorage points. They come in a variety of sizes, shapes and locking mechanisms to suit various applications and provide the most convenient type of connector as they can be easily attached and detached. They should be self-closing and self- or manual-locking and capable of being opened only by at least two consecutive deliberate manual actions.
  • Lanyard - A line usually used as part of a lanyard assembly to connect a harness to an anchorage point or static line in situations where there is risk of a fall.
  • Lanyard Assembly - An assembly of a lanyard and a personal energy absorber.
  • Locking Traveller (Horizontal) - A travelling anchorage. It has a walking sprocket device that connects the user to a static line system allowing the user to travel the entire length of the line without having to unclip and re-clip when passing the line supports.
  • Locking Traveller (Incline) - Arrests falls on surfaces up to an angle of 30 degrees.
  • Personal Energy Absorber (deceleration device) - An attachment designed to reduce the deceleration force imposed by a suddenly arrested fall. A personal energy absorber is designed to be used with a fallarrest harness and lanyard.
  • Restraint Line - The line securing workers to a point of anchorage and is used to prevent a person from reaching a point from which he or she could fall.
  • Safety Factor - This factor accounts for complex and variable dynamic forces and unknowns, such as rope ageing, metal fatigue, abrasion, bending and structure contact. It can, for example, be used to work out: - the ratio of the ultimate strength of the material to the permissible stress; - the ratio between the weakest link in the system compared to the maximum expected static load; or - the minimum breaking load and the safe working load.
  • Static Line - Is a horizontal or substantially horizontal line to which a lanyard may be attached and which is designed to arrest a free fall.
  • Total Fall Distance - The total distance a person is likely to fall during both the free and restrained parts of a fall and includes the maximum dynamic extension of all supporting components.

Fire Compartment                                     
The total space of a building or any part of a building separated from the remainder by fire barriers (walls, floors) with openings adequately protected. A fire compartment contains walls, floors and the like creating a compartment (or “box”) of any shape used to limit the spread of fire to another compartment or part of a building. Example; If any floor has an opening for an open stairway or escalator, a fire could spread through the opening—that floor would not form the boundary of a fire compartment. If there are no distinct fire barriers erected, then the whole building forms a fire compartment. If an Alternative Solution is used, the building elements used to form a fire compartment must have appropriate fire separation from the remainder of the building as determined by fire engineering principles. Sole-occupancy units are not generally regarded as fire compartments.

Fire Door

A building unsafe in case of fire because it will burn easily or because it lacks adequate exits or fire escapes.

Fire Wall                                                    
A solid wall of masonry, capable of resisting fire a specified period of time. Fire walls separate fire compartments. To avoid the spread of fire to another part of the building, a fire wall must extend from the fire-rated floor of a storey to the underside of the fire-rated floor above, or to a non-combustible roof covering. A “fire-resisting” wall is not necessarily a “fire wall”. A fire wall can sometimes be an external wall.

Fire-Isolated Passageway                        
A corridor, hallway or the like, of fire-resisting construction, which provides egress to or from a fire-isolated stairway or fire-isolated ramp or to a road or open space. A fire-isolated passageway protects people within a passageway from fire while evacuating. The whole passageway must be fire-protected from a fire outside the passage, including the floor, walls, ceiling, roof, any doors or other openings.

A stairway within a fire-resisting shaft and includes the floor and roof or top enclosing structure.

Fire-Resistance Level                              
(FRL) The grading periods in minutes for the following criteria: (a) Structural adequacy; (b) Integrity; and (c) Insulation, and are expressed in that order. Note: A dash means that there is no requirement for that criterion. For example, -/60/60 means there is no requirement for an FRL for structural adequacy.

Applies to fire-resisting building elements, including structural members and non-load bearing components, such as cladding, doors, windows and the like.

Fire-Source Feature                                  
A possible fire source external to the building from which a fire could spread to the building. A fire-source feature includes the far side of the road, and the side or rear boundary of an allotment. It also includes the far side of lakes, rivers and the like where the construction of buildings is unlikely. These represent the worst-case scenario for the spread of fire from another building. Even if a building on an adjacent allotment is set back from a boundary, the NCC assumes it could be demolished and another building constructed on the boundary.  Note that the term “fire-source feature” does not necessarily apply to a building, it relates to a potential source of fire. That potential may be realised in the future construction of a building. For this reason, the fire-source feature is not simply a line on the ground, nor a point at the top of a building; it is a continuous plane rising above that line or point.In this sense: a line drawn out horizontally from a building to a fire-source feature will hit that feature; and form a 90º angle with a line drawn down from the point at which it hits the fire-source feature to the ground, or the top of the adjoining building. However, some Deemed-to-Satisfy Provisions of the NCC limit the height above a building at which the fire-source feature remains active.

Frequency can be measured on a scale in units of Hertz (Hz). Higher frequency sound is generated by sources such as tire squeals or speech. Low frequency sound is generated by sources such as music subwoofers or truck engines. Low frequency sound is more difficult to control or reduce than high frequency sound and requires specialized design and construction.
