Ships and marine technology — Breathing apparatus for ships — Part 1: Emergency escape breathing devices (EEBD) for shipboard use

ISO 23269-1:2008 provides performance specifications for emergency escape breathing devices (EEBD) required by regulation in Part D of chapter II-2 of the 1974 International Convention for the Safety of Life at Sea (SOLAS), as amended in 2000, and chapter 3 of the IMO International Code for Fire Safety Systems (FSS Code). These devices are intended to supply air or oxygen needed to escape from accommodation and machinery spaces with a hazardous atmosphere. They are not intended for use in fighting fires, entering oxygen-deficient voids or tanks, or to be worn by fire-fighters.

Foreword

ISO (the International 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 has been

established has the right to be represented on that committee. International organisations, 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 electrotechnical 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 bodies 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 or all such patent rights.

ISO 23269-1 was prepared by Technical 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: Emergency escape breathing devices (EEBD) for shipboard use
⎯ Part 2: Breathing apparatus for shipboard firefighters

⎯ Part 3: Self-contained breathing apparatus (safety equipment) required for IMO IBC and IGC Codes

⎯ Part 4: Self-contained breathing apparatus for emergency escape required by the IMO IBC and IGC

ISO 23269-1:2008(E)
Introduction

The amendments of 2000 to Chapter II-2 of the 1974 International Convention for the Safety of Life at Sea

(SOLAS), which entered into force 1 July 2002, made the carriage of emergency escape breathing devices

(EEBD) mandatory on SOLAS ships. SOLAS and the related mandatory International Code for Fire Safety

Systems (FSS Code) prescribe basic performance requirements for EEBD. This part of ISO 23269 provides

more detailed requirements to ensure an adequate level of safety for users of these devices.

4.1 System design and performance

4.1.1 The EEBD shall have a minimum duration of service of 10 min under the conditions specified in 6.1.

4.1.2 The EEBD shall include a hood or full facepiece, as appropriate, to protect the eyes, nose and mouth.

Hoods and facepieces shall be constructed of flame resistant materials and include a clear window for viewing.

4.1.3 The EEBD shall be designed so that there are no protruding parts or sharp edges likely to be caught

on projections in narrow passages or that may hurt the wearer.

4.1.4 The EEBD shall be designed to ensure its full function in any orientation of the EEBD.

4.1.5 If the EEBD is equipped with a compressed air/gas cylinder, it shall be equipped with a reliable and

continuous means to show that the cylinder is fully charged and ready for use, without the necessity of

activating the EEBD.
4.1.6 The EEBD shall be capable of being carried hands-free.

4.1.7 A pressure indicator incorporating a suitable blow-out release shall be provided, such that in the event

of an explosion or fracture of the pressure indicator, the release shall be away from the wearer. The blow-out

release shall be protected from dirt and mechanical damages.

ISO 23269-1:2008(E)

4.1.8 If a window is incorporated in the pressure indicator, it shall be of non-splintering clear material.

4.1.9 The pressure indicator shall not contain oil.

4.1.10 The relief valve for the breathing bag of a closed circuit oxygen type device, if provided, shall be

designed so as to function properly in any orientation in the bag and be protected from dirt and mechanical

damages.

4.1.11 In the case of oxygen generated chemically, the EEBD shall be designed so as to prevent such

chemical from entering the wearer’s respiratory tract, and to ensure that saliva or condensate shall not

interfere with the function of the device or cause any harmful effect to the wearer.

4.1.12 The EEBD shall be designed so as to prevent inadvertent activation.

4.1.13 Dummy devices and components that are intended exclusively for training shall not be

interchangeable with operational devices or components, and shall be manufactured and marked in such a

way that they are clearly distinguishable from and cannot be inadvertently confused with operational devices.

4.1.14 Parts attached to the EEBD shall be firmly fixed so that they do not detach easily.

4.1.15 Compressed air/gas cylinders and their valves shall comply with appropriate national regulations.

4.1.16 Breathing hoses, if fitted, shall be flexible and non-kinking.

4.1.17 The air or gas provided in the cylinder shall be clean, dry, and free of contaminants. Compressed air

or oxygen shall comply with appropriate national or international standards for breathing air.

NOTE EN 12021 and EN 13794 are typical suitable standards for this purpose.

4.1.18 An EEBD shall withstand anticipated shock, when tested in accordance with the drop and shock tests

specified in Clause 5.5.

4.1.19 Where the EEBD is intended for storage in machinery spaces, a suitable container or cover such as a

box, bag or case shall be provided to prevent contamination (e.g. by oil, mist, or dust).

4.2 Facepiece and hood requirements

4.2.1 The finish of any part likely to be in contact with the wearer shall be free from sharp edges and burrs.

4.2.2 All components shall be able to be donned or removed with ease.

4.2.3 Transparent components shall not distort vision to the extent to affect the movement of the wearer.

4.2.4 The connection between the breathing apparatus and the facepiece or hood may be achieved by

either a permanent, special or thread type connector.

4.2.5 Dismountable connections shall be readily connected and secured, preferably by hand, and any

means of sealing used between components (e.g. O-rings or gaskets) shall be retained in position when the

connection(s) is (are) disconnected.

4.2.6 A mouthpiece, if fitted, shall facilitate reliable sealing and it shall not be possible to inadvertently block

the breathing circuit when the device is in operation. The mouthpiece shall be fitted with an adjustable or self-

adjusting harness if it is likely that an undue load is exerted on the wearer’s mouth otherwise.

4.2.7 A nose clip, if fitted, shall provide an airtight seal of the nose. It shall be flexibly attached to the

mouthpiece assembly such that, when fitting the mouthpiece, the wearer’s attention is automatically drawn to

the nose clip.

5 Resistance to environmental damage
5.1 General

5.1.1 The tests in 5.2 to 5.5 shall be conducted in the specified sequence with four sample EEBDs. After

each of the tests, each EEBD shall be visually inspected, and shall not break or develop deformation,

corrosion, or any other defects which may render it unsuitable for use.

5.1.2 At the completion of the test sequence, four of the sample EEBDs shall then be evaluated and tested

against the requirements of Clause 6, 6.8 excluded.
5.2 High temperature, high humidity test

Each sample EEBD shall be subjected to a temperature of (65 ± 2) °C in an atmosphere with relative humidity

of not less than 90 % for at least 48 h, and then left in an environment of 20 °C to 25 °C with a relative

humidity of (65 ± 10) % for at least 48 h.
5.3 Temperature cycling test

Each sample EEBD shall be subjected to a temperature of (−30 ± 2) °C for at least 8 h, and then to a

temperature of (65 ± 2) °C for at least 8 h, the cycle to be repeated 10 times.
5.4 Resonance and vibration tests

Each EEBD shall be subjected to the resonance tests specified in Table 1, followed by the vibration tests as

specified in Table 1.
