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.
In other circumstances, particularly when there is an urgent market requirement for such documents, a
technical committee may decide to publish other types of document:
— an ISO Publicly Available Specification (ISO/PAS) represents an agreement between technical experts in
an ISO working group and is accepted for publication if it is approved by more than 50 % of the members
of the parent committee casting a vote;
— an ISO Technical Specification (ISO/TS) represents an agreement between the members of a technical
committee and is accepted for publication if it is approved by 2/3 of the members of the committee casting
a vote.
An ISO/PAS or ISO/TS is reviewed after three years in order to decide whether it will be confirmed for a
further three years, revised to become an International Standard, or withdrawn. If the ISO/PAS or ISO/TS is
confirmed, it is reviewed again after a further three years, at which time it must either be transformed into an
International Standard or be withdrawn.
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.

2.10
wetting agent
water, or water to which surfactant has been added (to increase the ability of the liquid to penetrate), that is
applied to ACM to suppress dust emission during removal
3 Work categorization (grade) to minimize asbestos emissions and exposure during
ship recycling
In order to minimize the generation of asbestos dust and potential worker exposure during ship recycling
operations, the ship recycling facility's competent person shall determine the appropriate work grade in
accordance with Table 1, and shall determine corresponding working procedures in accordance with the
methodologies given in Table 2.
Since the difficulty of performing a task can be estimated by the type and manner of use of ACM, three work
grades have been established accordingly. See Table 1.
Table 1 — Work grading
Work grade Description
Work for removal of sprayed-on asbestos, which requires strict measures to minimize emission of
1 asbestos to environment and exposure of worker to asbestos such as thermal system insulation
or surfacing ACM
Work for removal of ACM except sprayed-on asbestos for thermal insulation for main and
2
auxiliary engines, thermal insulation for other pipes and armouring materials subjected to heat
Work for removal of ACM except sprayed-on asbestos used in accommodation and service
3 spaces; walls (ceilings, floorings and linings) and moulded seal materials for devices or piping
a
(joint sheets, gaskets, gland packing, packing and linings)
As factors such as workload, the working environment, and methodologies may vary, the competent person shall
periodically review tasks for asbestos abatement both before and during operations to determine if the work grade should
be amended.
The user shall ensure compliance with the national requirements.
a
When ACM is cut by power-tool, the work shall be categorized in work grade 2.

4 Preliminary check for asbestos-containing materials
In order to determine whether asbestos is used in the ship on which work is to be performed, the competent
person shall check
⎯ the inventory, and
⎯ the related documents and diagrams.
Equipment, systems or areas that are specified as free of asbestos need not be handled in the same way as
ACMs.
5 Planning removal of ACM
5.1 General
Prior to removal of ACM a written plan in accordance with 5.2 to 5.7 shall be made.
5.2 Operational overview
The operational overview shall specify the title of the operation, work period, details of the operation
(separately by area) and layout of work site indicated on the plan of the ship.
The overview shall specify the equipment, system or areas in which ACMs are used (based on the check
specified in Clause 4) and the work procedure summary for removal of ACM for each work grade. Additionally,
a layout for the removal zone shall be made giving dimensions and the precise location of work sites and
decontamination zones (in the case of work grade 1), negative-pressure dust collectors (in the case of work
grade 1) and the asbestos-containing waste storage.
The user shall ensure compliance with the national requirements.
Regardless of the work grade, removal of asbestos containing material should be conducted, to the maximum
extent practicable, prior to the removal of other hazardous materials or deconstruction of the vessel itself.
5.3 Organizational chart for managing asbestos removal
An organizational chart to manage asbestos removal shall be made. Especially when directly engaged in ACM
removal operations, the employer should attach the document of authorization to perform ACM removal to the
chart if necessary.
Documents showing that workers have completed the necessary training and have undergone medical
checkups for the specified operations shall be attached to the organizational chart.
5.4 Operating schedule
For items related to the operating schedule, see the removal procedure specified in Clause 6. The schedule
should indicate the number of days required for each operation.
5.5 Removal written plan
The removal written plan shall provide information in accordance with the removal procedure specified in
Clause 6, in addition to the information required by 5.5.1 and 5.5.2.

---------------------- Page: 7 ----------------------
ISO/PAS 30007:2010(E)
5.5.1 Equipment, tools and protective measures
The written plan shall contain a list of equipment and tools needed for removal.
The list shall specify the types and quantities of personal protective equipment required for each job (or task)
performed, including but not limited to respirators and protective clothing.
The manufacturers, product names and quantities of wetting agent shall be specified.
5.5.2 Layout of the decontamination zone
The written plan shall incorporate a layout and structural diagram of the decontamination zone [equipment
room (change room), shower area, and clean room] and other illustrations that illustrate operational specifics,
such as the location of the negative-pressure dust collector.
5.6 Asbestos monitoring plan
If asbestos monitoring (atmosphere, working environment, water, and soil) is required in accordance with
national law, there shall be a written plan to specify measuring cycles, locations, methods and designated
persons or organization.
5.7 Waste disposal plan
The waste disposal plan shall specify methods for storage, transport, and final disposal of removed ACM. The
plan shall also specify the estimated quantity of the ACM wastes.
6 Work procedures for each work grade
6.1 General
Operations for each grade shall be performed in accordance with the procedures specified in Table 2. For
additional information see 6.2 to 6.4.
6.2 Work grade 1
6.2.1 General
Asbestos removal operations of work grade 1 shall be carried out as specified in 6.2.2 to 6.2.7.
6.2.2 Preparation for work
Preparation of tools, material and equipment shall be conducted in accordance with the asbestos-removal
plan specified in Clause 5, before starting the asbestos removal operation.
