8、nternational Organization for Standardization) is a worldwide federation of national standards bodies (ISO member bodies). The work of preparing International Standards is normally carried out through ISO technical committees. Each member body interested in a subject for which a technical committee

9、has been established has the right to be represented on that committee. International organizations, governmental and non-governmental, in liaison with ISO, also take part in the work. ISO collaborates closely with the International Electrotechnical Commission (IEC) on all matters of electrotechnica

10、l standardization. International Standards are drafted in accordance with the rules given in the ISO/IEC Directives, Part 2. The main task of technical committees is to prepare International Standards. Draft International Standards adopted by the technical committees are circulated to the member bod

11、ies for voting. Publication as an International Standard requires approval by at least 75 % of the member bodies casting a vote. Attention is drawn to the possibility that some of the elements of this document may be the subject of patent rights. ISO shall not be held responsible for identifying any

12、 or all such patent rights. ISO 23269-2 was prepared by Technic al Committee ISO/TC 8, Ships and marine technology, Subcommittee SC 1, Lifesaving and fire protection. ISO 23269 consists of the following parts, under the general title Ships and marine technology Breathing apparatus for ships: Part 1:

13、 Emergency escape breathing devices (EEBD) for shipboard use Part 2: Self-contained breathing apparatus for shipboard firefighters Part 3: Self-contained breathing apparatus (safety equipment) required by the IMO IBC and IGC Codes Part 4: Self-contained breathing apparatus for emergency escape requi

14、red by the IMO IBC and IGC Codes ISO 23269-2:2011(E)iv ISO 2011 All rights reservedIntroduction Chapter II-2 of the International Convention of Safety of Life at Sea 1974 (SOLAS 74), as amended, requires carriage by ships of breathing devices for firefighting purposes. The International Maritime Org

15、anization (IMO) International Code for Fire Safety Systems (FSS Code) specifies basic performance requirements for these devices. However, neither SOLAS 74 nor the FSS Code provides specifications in sufficient detail to ensure an adequate level of safety for users. This part of ISO 23269 provides d

16、etailed technical specifications for shipboard breathing apparatus, to supplement the basic requirements in the FSS Code. It takes into account existing European standards for firefighters outfits for use by professional firefighters, such as EN 136 and E N 137. However, it also takes into account t

17、hat ships crews are generally not professional firefighters, and require a more user-friendly ensemble than that specified in the EN standards.

18、2: Self-contained breathing apparatus for shipboard firefighters 1 Scope This part of ISO 23269 specifies self-contained breathing apparatus for firefighters on board ships, which are required to be carried on ships by Part C (Suppression of Fire) of chapter II-2 of the 1974 International Convention

19、 of Safety of Life at Sea (SOLAS 74), as amended, and chapter 3 of the International Code for Fire Safety Systems (FSS Code). Although the breathing apparatus manufactured in accordance with this part of ISO 23269 are intended for use in fighting small to medium magnitude fires before the operation

20、of any installed fixed firefighting systems, they are not intended or suitable for direct entry into flames. 2 Normative references The following referenced documents are indispensable for the application of this document.

26、thing device which connects the wearers respiratory tract to the other parts of the device and isolates the respiratory tract from ambient atmosphere 3.3 visor part of the facepiece which meets the field of vision requirement of this part of ISO 23269 and can in addition provide eye protection 3.4 c

27、avity space between the visor and the inner mask adjacent to the face seal 4 General design requirements Breathing devices shall comply with the following requirements and be tested in accordance with Clauses 5 a n d 7. 4.1 Breathing apparatus shall be of the self-contained compressed air-operated t

28、ype for which the volume of air contained in the cylinders shall be at least 1 200 l. 4.2 The breathing apparatus shall be of simple and reliable construction and as compact as possible. The design of the breathing apparatus shall be such as to allow its reliable inspection. 4.3 The breathing appara

29、tus shall be sufficiently robust to withstand the rough usage it is likely to receive in service. 4.4 The breathing apparatus shall be designed so that there are no protruding parts likely to be caught on projections in narrow passages. 4.5 The finish of any part of the breathing apparatus likely to
