This document has the general title Fixed fire-fighti
18、ng systems Condensed aerosol extinguishing systems and will consist of the following parts: Part 1: Requirements and test methods for components; Part 2: Design, installation and maintenance. PD CEN/TR 15276-1:2009CEN/TR 15276-1:2009 (E) 5 Introduction It has been assumed in the preparation of this
19、document that the execution of its provisions is entrusted to appropriately qualified and experienced people in the specification, design, installation, testing, approval, inspection, operation and maintenance of systems and equipment, for whose guidance it has been prepared, and who can be expected
20、 to exercise a duty of care to avoid unnecessary release of extinguishant. Product certification: Users of this document are advised to consider the desirability of independent certification of product conformity with this document based on testing and continuing surveillance, which may be coupled w
21、ith assessment of manufacturer quality systems against EN ISO 9001. Fire-fighting systems covered in this document are designed to provide a supply of fixed condensed aerosol extinguishing medium to extinguish fire. The requirements of this document are made in the light of the best technical data k
22、nown to the working group at the time of writing but, since a wide field is covered, it has been impracticable to consider every possible factor or circumstance that might affect implementation of the requirements. It is important that the fire protection of a building or plant be considered as a wh
23、ole. Aerosol extinguishant systems form only a part, though an important part, of the available facilities, but it should not be assumed that their adoption necessarily removes the need to consider supplementary measures, such as the provision of portable fire extinguishers or other mobile appliance
24、s for first aid or emergency use, or to deal with special hazards. Aerosol extinguishants have been recognized as effective media for the extinction of Class A fires (solid surface burning fires) and Class B and Class C fires according to EN 2, but it should not be forgotten, in the planning of comp
25、rehensive schemes, that there may be hazards for which these mediums are not suitable, or that in certain circumstances or situations there may be dangers in their use requiring special precautions. Advice on these matters can be obtained from the appropriate manufacturer of the aerosol generators o
26、r the extinguishing system. Information may also be sought from the appropriate fire authority, the health and safety authorities and insurers. In addition, reference should be made as necessary to other national standards and statutory regulations. It is essential that fire-fighting equipment be ca
27、refully maintained to ensure instant readiness when required. Routine maintenance is liable to be overlooked or given insufficient attention by the owner of the system. It is, however, neglected at peril to the lives of occupants of the premises and at the risk of crippling financial loss. The impor
28、tance of maintenance cannot be too highly emphasised. Condensed aerosol may contain traces of toxic substances like those produced by a fire, and will obscure vision like smoke from fire. PD CEN/TR 15276-1:2009CEN/TR 15276-1:2009 (E) 6 1 Scope This document specifies requirements, describes test met
29、hods for condensed aerosol extinguishing components and covers solely condensed aerosols. This document is not intended to indicate approval of the extinguishants listed herein by the appropriate authorities, as other extinguishants may be equally acceptable. This document is intended as a standard
30、covering solely condensed aerosol. The condensed aerosol generator typically consists of the following main components: a) solid aerosol-forming compound; b) cooling mechanism; c) ignition device(s); d) end plate discharge outlet(s); e) housing; f) mounting bracket. This document does not cover disp
31、ersed aerosols. This document requires, as a precaution, that the room is evacuated and sealed off whenever a generator is activated. Precautions include evacuation of the proximity area, criteria for re-entering and other safeguards as stated in Clause 5 of CEN/TR 15276-2:2009. 2 Normative referenc
