Fire safety engineering concerning evacuation from buildings CFPA-EGuidelineNo19:2023F 600 0 CFPAEUROPE? Fire Safety |Security |Natural Hazards
The CFPA Europe develops and publishes mon guidelines about fire safety security and natural hazards with the aim to achieve similar interpretation and to give examples of acceptable solutions concepts and models. The aim is to facilitate and support fire protection security and protection against natural hazards across Europe and the whole world. Today fire safety security and protection against natural hazards form an integralpart ofamodern strategy for survival sustainability， and petitiveness.Therefore the market imposes new demands for quality. These Guidelines are intended for all interested parties and the public. Interested parties includes plant owners insurers rescue services consultants safety panies and the like so that in the course of their work they may be able to help manage risk in society. The Guidelines reflect best practice developed by the national members of CFPA Europe.Where these Guidelines and national requirements conflict national requirements shall apply. This Guideline has been piled by the Guidelines Commission and is adopted by the members of CFPA Europe.

GUIDELINENo19:2023F 1Introduction Saving human life is the most important objective in fire protection processes. Proper evacuation plans are essential to reach this objective. Two methods can be considered: The first is the prescriptive method which deals with the occupancy size and number of exits together with the maximum length of the escape routes; evacuation. The first method is based on three main points: density of people; flow of people; length and width of evacuation routes. time. 2Scope The main scope of this guideline is to supply valid support for the evacuation strategy to allow any kind of occupants anywhere within the structure to be able to evacuate to a place of safety. 3Definitions Actions: Actions which may affect the pliance of the works with the essential requirements mechanical chemical biological thermal and electro-magnetic agents. and property by detecting fire extinguishing fire removing smoke and hot gases or any bination of these functions. Alarm: Sudden attention or action for protection of persons or property (ISO 8201 1987). concentration of toxic bustion gases that seriously endanger life safety in a certain time. Design fire scenario: A design fire scenario is a subsystem of all possible fire scenarios and represents the most probable or onerous of them. The Design fire scenarios are specific fire scenarios on which an analysis of performance will be conducted. to a final exit. Available safe egress time (ASET): Calculated time available between ignition of a fire and the time at which tenability criteria are exceeded in a specific space in a building. CFPA-E*-GUIDELINES
5GUIDELINENo19:2023F Escape time: Calculated time from the ignition until the time at which all the occupants of a specified part of a building are able to reach place of safety. Evacuation time: In relation to the orderly movement of persons to a place of safety in case of fire or other emergency this is the interval between the time of a warning of fire being transmitted to the occupants and the time at which all of the occupants are able to reach a place of safety safety. Exit signs: Signs which clearly indicate an exit. Fire: A process of a not controlled bustion characterized by emission of heat acpanied by smoke and / or flame. Fire alarm installation: Combination of ponents whose purpose is to give an audible and / or visible and / or other perceptible alarm of fire. The system may also initiate other ancillary actions. Fire alarm alarm of fire: Warning of a fire originated by a person or by an automatic device Fire rescue team: Public or private organization with the aim of safeguarding life and fighting fires. Fire partment: An enclosed space in a building that is separated from other parts of the same building by enclosing construction having a specified period of fire resistance within which a fire can be contained (or from which a fire can be excluded) without spreading to (or from) another part of the building. changes acpanying a fire. Fire door: A door or shutter which together with its frame and furniture as installed in a building when closed is capable of meeting specified performance criteria concerning the resistance to fire. Fire exposure: Thermal actions affecting the product. Fire hazard: The potential to lose a life (or injury) and / or damage a property by fire. time the required load bearing function integrity and / or thermal insulation specified in the standard fire resistance test. installations for means of escape suppression and firefighting equipment.
