Implementation of SOLAS II-1, Regulation 3-5
and MSC.1/Circ.1379
SOLAS Chapter II-1, Regulation 3-5“From 1 January 2011, for all ships, new installation of materials which contain asbestos shallbe prohibited.”
MSC.1/Circ.1379“In the context of this regulation, new installation of materials containing asbestos means any
new physical installation on board. Any material purchased prior to 1 January 2011 being
kept in the ship's store or in the shipyard for a ship under construction, should not be
permitted to be installed after 1 January 2011 as a working part.”
Unified Interpretations
SOLAS II-1, Regulation 3-5
1. Verification that “new installation of materials which contain asbestos” under SOLAS II-1/35 is not made on ships requires the Recognized Organization to review asbestos-freedeclarations and supporting documentation, for the structure, machinery, electricalinstallations and equipment covered by the SOLAS Convention, which is to be provided to theRecognized Organization by shipyards, repair yards, and equipment manufacturers taking
into account appendix 6 of the 2023 Guidelines for the development of the inventory ofhazardous materials (resolution MEPC.379(80)) for:-new construction (keel laid, or at a similar stage of construction, on or after 1 July2012);-conversions (contract date for the conversion or, in the absence of a contract, the dateon which the work identifiable with the specific conversion begins) on or after 1 July2012;

NOTES:
1. This Unified Interpretation is to be uniformly implemented by IACS Societies not later
than 1 July 2012.
2. Revision 1 of this Unified Interpretation is to be uniformly implemented by IACS
Societies not later than 1 July 2013.
3. Revision 2 of this Unified Interpretation is to be uniformly implemented by IACS
Societies on ships not later than 1 January 2025.

MSC.1/Circ.1379
2. The phrase “new installation of materials containing asbestos”1 in MSC.1/Circ.1379:-means that material used (i.e., repaired, replaced, maintained or added) as a working
part of the ship as per Annex 1 which is installed on or after 1 July 2012 is required tobe documented with an asbestos-free declaration. The Administration or RecognizedOrganization shall review this documentation, in consultation with the Company’s
nominated person responsible to control asbestos containing material onboard as per
the Safety Management System in accordance with the Guidelines for maintenance andmonitoring of on-board material containing asbestos (MSC/Circ.1045), during annual
safety construction and safety equipment surveys; and-does not preclude the stowage of material which contains asbestos onboard (e.g.,spare parts existing on board as of 1 July 2012).

3. The phrase “should not be permitted to be installed after 1 January 2011 as a working part”
in MSC.1/Circ.1379 means that replacement, maintenance or addition of materials whichcontain asbestos used for the structure, machinery, electrical installations and equipment
covered by the SOLAS Convention is prohibited.

1"Materials containing asbestos" means that asbestos is present in the product/material above the thresholdvalue stipulated in row A-1 of the table A of appendix 1 of resolution MEPC.379(80).
