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 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 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 23269-3 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: 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 required by the IMO IBC and IGC
Codes

Introduction
The IMO IBC Code (for bulk chemicals) and the IMO IGC Code (for gas carriers) developed by the
International Maritime Organization require that self-contained breathing apparatus (safety equipment) be
carried on board chemical tankers and gas carrier ships. However, these Codes do not technically specify the
details of such apparatus; such a specification is necessary to provide a sufficient safety level for users.

INTERNATIONAL STANDARD ISO 23269-3:2011(E)

Ships and marine technology — Breathing apparatus for
ships —
Part 3:
Self-contained breathing apparatus (safety equipment) required
by the IMO IBC and IGC Codes
1 Scope
This part of ISO 23269 provides performance specifications of the self-contained air-breathing apparatus
(SCBA) (not using stored oxygen) required by the IMO IBC Code (for bulk chemicals) and the IMO IGC Code
(for gas carriers) developed by the International Maritime Organization.
The breathing apparatus manufactured in accordance with this part of ISO 23269 constitutes an element of
the set of safety equipment which permits personnel to enter a gas-filled compartment and perform work there.
The breathing apparatus is not intended for use in fighting fires or suitable for entry into flames.
