2 2.0. DEFINITIONS OF TECHNICAL FIRE SAFETY TERMS USED 2.1. In fire safety reporting and specifications, the terms / words and associated meanings will be used: 'Shall' and 'Must' 'Will' 'Should' 'Provide' 'Approved' 'Suitable' Are Mandatory (you will do) Is Informative Is Advisory Means - supply, fix or Install Means - Approved in Writing Means - suitable in the opinion of the authority having jurisdiction 2.2. Various terms are used in fire safety guides and documentation because of their importance concerning the Means of Escape for existing buildings, are defined below. Access Room Accommodation Stairway Cavity Barrier Compartment Compartment Wall or Floor Dead-End Condition Distance of Travel Emergency Escape Lighting Final Exit Means - a room, which forms the only, escape route from an inner room (See Inner Room); Means - a stairway, which is provided for the convenience of occupant; in addition, to that or those required for escape purposes; Means - a construction provided to close a concealed space against penetration of smoke or flame, or provided to restrict the movement of smoke or flame within such a space; Is a part of the building separated from all other parts of the same building by fire resisting compartment walls and /or compartment floors; Means - a fire-resisting wall or floor used in the separation of one fire compartment from another; Means - an area from which escape is possible in one direction only; Means - the actual distance that a person needs to travel between any point in a building and the nearest storey exit; Means - that part of the emergency lighting system provided for use when the supply to the normal lighting fails so as to ensure that the Means of Escape can be safely and effectively used at all material times; Means - the termination of an escape route from a building giving direct access to a Place of Safety such as a street, passageway, walkway or open space, and sited to ensure that persons can disperse safely from the vicinity of the building and the effects of fire; Date Last Amended: Dec 15 2.

3 2.2. Continued: Fire Door Fire-Resisting (Fire Resistance) Fire Safety Engineering Fire / Smoke stopping Inner Room Means of Escape Members of the Public Place of Safety Protected Corridor Means - a door assembly which is designed to hold back fire and smoke for a designated period, and has been tested under the following: Notes: The conditions of test for door assemblies described in British Standard 476: Part 22; or, The conditions of test contained in the British Standard currently in force at the time of the bringing into use of the premises as a factory, office, shop or railway premises; or, The conditions of test in the British Standard currently in force at the time the door was manufactured; would satisfy the criteria for integrity for 20 minutes or for such longer periods, as may be specified in particular circumstances; 1. Normally, such doors should be positively self-closing; 2. Door assemblies with non-metallic leaves should be maintained in accordance with the provisions of British Standard 8214; Means - the ability of a component or the construction of a building to satisfy for a stated period of time some or all of the appropriate criteria specified in the relevant part of British Standard 476; Note - in existing premises, it may not be possible to define the fire resistance of some elements of structure, and a judgement will need to be made on whether the fire resistance is acceptable; Means - an approach, which takes into account the total fire safety package and sets a range of fire safety features against an assessment of the fire hazard and fire risk for the particular premises; Means - seals provided to close an imperfection of fit or design tolerance between elements or components to restrict the passage of fire, heat and smoke; Means - a room from which escape, is possible only by passing through an access room (Note: Inner Rooms are not permitted (travel from inner room to Access Room, only discharging to safety such as corridor etc.) ; Means - the structural means whereby a safe route is provided for persons to travel from any point in a building to a place of safety beyond the building without outside assistance; Guests - not being employed or studying at UCL; Means - place beyond the building in which a person is no longer in danger from fire Means - corridor, which is adequately protected from fire in adjoining accommodation by fire-resisting construction (usually to a minimum of 30 minutes Fire Resting Standard; Date Last Amended: Dec 15 3.

4 2.2. Continued: Protected Lobby Protected Route Protected Stairway Storey Exit Vision Panel (VP) Means - a fire-resisting enclosure providing access to a protected stairway via two sets of fire-resisting and self-closing doors, into which no rooms open, other than toilets or lifts; Means - a route having an adequate degree of protection from fire including walls (other than any part that is an external wall of a building), doors, partitions, ceilings and floors separating the route from the remainder of the building; Means - a stairway, which is adequately protected from fire in adjoining accommodation by fire-resisting construction and either discharges through a final exit or a protected route leading to a final exit; Means - an exit through which persons are no longer at immediate risk from the effect of fire and includes a final exit, an exit to a protected lobby or protected stairway (including an exit leading on to an external stairway), and an exit provided for Means of Escape through a compartment wall via which a final exit can be reached; Means - a fire resisting or plain glazed panel found in doors or partitions, placed there for safety to view an access room circulation traffic beyond the door; Date Last Amended: Dec 15 4.
