2013 REVISION CYCLE
A SUMMARY OF THE CHANGES
There were about 110 suggested changes proposed
to 306, the most in recent memory.
The committee initially spent two full days
reviewing each proposal in January and another full
day in September reviewing 49 comments on the
initial proposals.
As we go through the major changes in this presentation you
will begin to notice a shift in 306 to enable it to provide
direction for spaces which are not cargo tanks and are not
adjacent to cargo tanks.
This presentation will not cover every change, only the major
ones.
SCOPE
Modified scope to show 306 can be applied to other spaces within the
shipyard (Log 69, pg 4)
1.1.5 This standard applies specifically to those spaces on vessels that are
subject to concentrations of combustible gas, flammable and toxic liquids,
vapors, gases, and chemicals as here-in after described. This standard is
also applicable in those spaces on vessels that might not contain sufficient
oxygen to permit safe entry. This standard shall also apply may also be
applied other spaces aboard vessels to ensure, and promote safe working
conditions.
1.1.5.1 When requested the Marine Chemist shall apply this standard to
other spaces to ensure and promote safe working conditions. (Log 104, 96,
99. pg 4,14,60)
1.1.6 This standard applies to land-side confined spaces, whether stationary
or mobile, underground and above ground storage tanks, or other hollow
structures throughout a shipyard such as tank trucks, railroad tank cars,
power plant fuel tanks, storage tanks, dip and laundry tanks, vaults, tunnels
or other spaces that may contain dangerous atmospheres located within the
boundaries of a shipyard or ship repair facility.
Governmental Regulations
Removed wording stating that the standard cannot supersede governmental regulations. OSHA
stated that a NFPA standard can exceed minimum governmental regulations if the committee
feels it enhances worker safety (Log72 Pg 5)
1.4* Governmental Regulations. Nothing in this standard shall be construed as superseding
existing requirements of any governmental or local authority. The intent of this standard is to
assist those using it to meet minimum governmental safety objectives. Attention of owners,
repairers, and Marine Chemists is directed to the rules and regulations for tank vessels in 46 CFR
35, "Operations," and other rules and regulations for vessel inspection of the United States Coast
Guard and the Occupational Safety and Health Administration Standards (OSHA) of the United
States Department of Labor, in 29 CFR 1915, which prescribe an inspection prior to making
repairs involving hot work and prior to entering spaces where oxygen deficiency can exist. Those
standards provide, under the conditions stated therein, for inspection by a Marine Chemist
certificated by the National Fire Protection Association or, alternatively, for inspection by certain
other persons.
A.1.4 All applicable regulations, requirements, and standards should be consulted. Some of the
requirements in this standard might exceed differ from minimum governmental regulations to
better protect personnel and property.
Adjacent Spaces
Changed Definition
3.3.1 Adjacent Spaces. Those spaces in all directions from subject
space, including all points of contact, corners, diagonals, decks, tank
tops, and bulkheads, and including areas affected by hot work,
where slag, products of combustion, and sparks would be expected
to fall or accumulate. (Current wording)
3.3.1 Adjacent Spaces. Those spaces in all directions from subject
space, including all points of contact, corners, diagonals, decks, tank
tops, and bulkheads. Pipelines are not adjacent spaces and are
considered Not Safe for Hot Work unless noted on the Marine
Chemist Certificate. (ROC 306-3, pg. 2)
(This definition reverts back to a point of contact definition,
addressing areas affected by hot work has been moved to 4.2.2.)
Revised Hot Work Definition
3.4.2* Hot Work. Any activity involving any of the following:
(A) Riveting, welding, burning, the use of powder actuated tools or similar
fire producing operations, or,
(B) Any operation that raises the temperature of the work piece equal to or
greater than 204°C (400°F). or higher.
(C)*Grinding, drilling, abrasive blasting, the activation of non-intrinsically
safe or non-explosion-proof equipment or similar operations, in the presence
of or against accumulations of readily combustible materials, or flammable or
combustible liquids gasses or their vapors when the atmosphere exceeds 10
percent of the LEL.
(Log 102 pg 16)(Changed in ROC 306-6 pg 5)
A.3.4.2.(C) Grinding, drilling, abrasive blasting, or similar spark-producing
operations should always be considered hot work when conducted in the
presence of accumulations of flammable gases, flammable or combustible
liquids, their vapors or accumulations of other common combustible
materials. (ROP 306-106 pg 60)
Changes to Calibration Wording
4.2.1.1* The accuracy and sampling integrity of all instruments used by the
Marine Chemist shall be verified before each day's use. by using with a known
concentration of test gases in a manner consistent with the manufacturer's
recommendations.
4.2.1.2 Calibration of sensors shall be verified using a known concentration of
test gas. in a manner consistent with the manufacturer's recommendations.
4.2.1.2 3 A record of verification of accuracy or calibration This record of
calibration shall be maintained for at least 3 months.
A.4.2.1.1 It is recognized that in limited circumstances the marine chemist
may not be able to transport compressed calibration gas by air. In these
limited cases the chemist shall should make every attempt to verify the
accuracy of their instruments prior to use. (Logs 75 and 76 Pg. 18)
Marine Chemist Determinations
4.2.2 The Marine Chemist's determinations shall include a visual inspection and tests of the spaces
to be certified, and for repair or alterations involving hot work, all adjacent cargo tanks, spaces
adjacent to cargo tanks, and other adjacent spaces containing or having contained flammable or
combustible cargo, fuels, or oils spaces and other spaces/areas that may be affected by the hot
work are treated in accordance with 4.3.4(4) and 4.3.4(5). The inspection shall include spaces or
areas where products of hot work such as sparks, slag or embers can act as ignition sources.
The determinations also shall include the following:
(1) The three previous cargo loadings
(2) Nature and extent of the work
(3) Starting time and duration of the work
(4) Tests of cargo and vent lines at manifolds and accessible openings associated with the scope of
work on or in the compartments concerned
(5) Verification that pipelines that could release hazardous materials into spaces that will be
certified for entry and/or hot work ATMOSPHERE SAFE FOR WORKERS or SAFE FOR
HOT WORK are either disconnected, blanked off, or otherwise blocked by a positive method, or
the valves are positioned and tagged in such a manner to prevent, or by written notice restrict,
operation
(6) Tests of cargo heating coils.
(7) In spaces which are not cargo tanks or are not adjacent to cargo tanks the Marine Chemist
shall carry out tests to determine the atmospheric or fire hazards that may exist within each
affected compartment or space, and any adjacent spaces which may be affected by hot work,
ensuring compliance with the minimum applicable requirements prior to issuing a Certificate.
(ROP 306-29 pg. 20. ROC Pg 8 Log 18)
4.3.1(3)* Any toxic chemicals in the atmosphere
associated with cargo, fuel, tank coatings,
inerting mediums, adjacent spaces, or
fumigants are within permissible
concentrations at the time of inspection.
NO CHANGE TO TOXICITY DIRECTION
(ROC 306-14 Log 30 pg. 13)
If a PEL and a TLV exist for a substance does 306
require the CMC to use the lower of the two?
If there is no PEL listed does but there is a TLV, does
306 require the CMC to use the TLV?
If there is no PEL does 306 require the CMC to make
any measurement at all?
What is the definition of "permissible
concentrations"
ASFW Change 4.3.1.(4)
4.3.1* ATMOSPHERE SAFE FOR WORKERS requires that in the

Certificate shall be written legibly. If ink stamps are used,
all copies of the Certificate shall be stamped and legible.
(Log 33, pg 40)(This was changed back to its
initial wording during the ROC review.)
Preparation of Certificates
4.4.3* Such qualifications and requirements shall include precautions, including
protective equipment and devices, necessary to eliminate or minimize hazards that
could be present from protective coatings or residues from cargoes. These
qualifications also shall include limitations or restrictions, if any, on the areas where
work is to be done. (Current wording)
4.4.3 Such qualifications and requirements shall include precautions, including
protective equipment and devices, necessary to eliminate or minimize hazards that
could be present from combustibles, protective coatings or residues from cargoes.
These qualifications shall include limitations or restrictions, if any, on the areas where
work is to be done and shall be listed on the certificate.
A.4.4.3 If there is no additional statement regarding the scope of the work on the
Certificate, any hot work or cold work can proceed as indicated by the standard
safety designation. If all types of work cannot be conducted safely under a standard
safety designation, then the authorized work or prohibited work should be listed on
the Certificate. (Log 82, pg. 41) (Deleted Annex Section)
Obtaining the Certificate
4.61 (D) Only one requestor will be listed on
the certificate. The requester is responsible
for providing a complete statement of the
scope of the work at the time of the Marine
Chemist’s inspection… (ROC Log 36, pg.30)
Maintaining the Certificate 4.6.2
4.6.2(3)*Unless otherwise stated on the Certificate, all spaces including adjacent spaces
documented on the .Marine Chemist Certificate shall be reinspected daily, or more often as
necessary, by the shipyard competent person in support of work prior to entry or
recommencement of work.
4.6.2(3)* Unless otherwise stated on the Certificate, certified spaces including spaces
adjacent to hot work, where work is being done shall be re-inspected daily, or more often as
necessary, by the shipyard competent person, prior to entry or external hot work.
(5) (4) It is the responsibility of the Certificate requester, vessel owner, or their
representative to ensure that the prescribed work is carried out at the original location
within the facility for which the Certificate was issued, unless movement is authorized
within that facility by the Marine Chemist on the Certificate. If movement is authorized
within the facility, a reinspection shall be performed by a competent person. The Marine
Chemist shall include on the Certificate the nature of any tests to be performed after the
move is complete and prior to beginning work.
(6) (5) The calibration of all instruments used by a competent person to maintain a Marine
Chemist’s Certificate shall be verified by either the competent person, another qualified
individual, or metrology laboratory, before each day’s use by using a known concentration
of test gas in a manner consistent with the manufacturer’s recommendations. A record shall
be maintained for at least 3 months.
(4) (6) Certificates not maintained according to the requirements in 4.6.2(1) through (5)
shall be void.
Log 30 pg. 45 Log 83 pg 44
Annex to 4.6.2(3)
A.4.6.2(3) The Marine Chemist can recognize a facility's procedures and infrastructure used to
minimize risk and hazards to people and equipment through engineering controls supplemented
by administrative controls. As an example, mechanical exhaust ventilation for the space has been
installed and will operate continuously. OSHA, in 29 CFR 1915.13, notes that the frequency of
retesting the atmospheric conditions of a space should be a function of several factors, including
temperature, work in the tank, period of time elapsed, unattended tanks, work breaks, or
ballasting. This section allows the rotation of work away from spaces that have been certified and
worked in or on, but where work has been suspended due to schedule requirements. It requires
the shipyard competent person (if not the Marine Chemist) to reinspect and establish that safe
conditions remain in certified spaces and applicable adjacent spaces before work resumes in or on
such spaces. Vessel or shipyard management must always be aware however. that any suspension
of work in or on a confined or enclosed space constitutes a time for significant potential
accumulation of hazards. and careful and documented reinspection before reentry and
resumption of work is a strict necessity and requirement.
The intent of this wording is to clarify that spaces listed on the Marine Chemist Certificate do not
need to be tested by the competent person unless work is being done on or in a space. For
example, spaces on a certificate do not need to be tested and inspected on a weekend if no work
or entry is taking place. However, nothing shall prevent a competent person from testing more
frequently than the minimum.
Log 83 pg 45, Log 30 pg 46, Log 98 pg 65
Preparing Vessels
5.1.1 All cargo pumps, cargo lines, inert gas
lines, crude oil wash lines, piped cargo fireextinguishing lines, vapor control and recovery
lines and vent lines to the spaces involved in the
scope of work shall have been flushed with
water, blown with air or inerted.
ROP 306-75. pg. 46
25 Foot Rule
5.8* Vessel Fuel Oil Tanks. No hot work shall be permitted immediately
adjacent to any vessel's fuel oil tanks unless the work has been authorized by
the Marine Chemist.
A.5.8 Vessel or other Fuel Oil Tanks. On dry cargo vessels, miscellaneous
vessels, passenger vessels, and shipyard employment land-side operations no
hot work shall be permitted adjacent to any vessel's or other fuel oil tanks
unless the work has been authorized by the Marine Chemist. When the
adjacent space contains flammable or combustible liquids with a flash point at
or below 150 degrees-Fahrenheit, or flammable gasses and the distance
between such spaces and the hot work is greater than 25 feet, then a
competent person can visually inspect and test the space (if the hot work is 25
feet or closer to the adjacent space containing such flammables, then a Marine
Chemist must certify the hot work.)
(Log 88 Pg 52)
6.3.4 All tanks, confined spaces, and machinery compartments
in which internal repairs or alterations are to be undertaken
shall be cleaned to comply with the requirements of either
4.3.1 or 4.3.3. For repair or alteration involving hot work,
these spaces shall meet the requirements of 4.3.4 or 4.3.6 or
5.1.3 and adjacent compartments shall be cleaned to meet the
requirements of 4.3.4 or 4.3.6 or 5.1.3 or shall be permitted to
be inerted to meet the requirements of 4.3.8. The adjacent
spaces shall be permitted to be secured in accordance with the
Marine Chemist’s requirements and acknowledged on the
Certificate.
Exception: Spaces covered by 5.1.3, Section 5.8, and 6.3.3.
