producing actions may be made aboard
a vessel.
(b) Until an inspection has been made
to determine that such operation can
be undertaken with safety, no alterations, repairs, or other such operations involving riveting, welding,
burning, or like fire-producing actions
must be made:
(1) Within or on the boundaries of
cargo tanks which have been used to
carry combustible liquid or chemicals
in bulk;
(2) Within or on the boundaries of
fuel tanks; or,
(3) To pipe lines, heating coils,

(c) Such inspections must be made
and evidenced as follows:
(1) In ports or places in the United
States or its territories and possessions
the inspection must be made by a marine chemist certificated by the National Fire Protection Association.
However, if the services of such certified marine chemist are not reasonably available, the Officer in Charge,
Marine Inspection (OCMI), upon the
recommendation of the vessel owner
and his or her contractor or their representative, must select a person who,
in the case of an individual vessel,
must be authorized to make such inspection. If the inspection indicated
that such operations can be undertaken with safety, a certificate setting
forth the fact in writing and qualified
as may be required, must be issued by
the certified marine chemist or the authorized person before the work is
started. Such qualifications must include any requirements as may be
deemed necessary to maintain the safe
conditions in the spaces certified
throughout the operation and must include such additional tests and certifications as considered required. Such
qualifications and requirements must
include precautions necessary to eliminate or minimize hazards that may be
present from protective coatings or
residues from cargoes.
(2) When not in such a port or place,
and a marine chemist or such person
authorized by the OCMI, is not reasonably available, the inspection must be
made by the master or person in charge
that the vessel’s lifesaving and fire
suppression and detection equipment
complies with the applicable requirements of parts 141 and 142 of this subchapter and is in good working order.

(b) Each towing vessel must be capable of preventing all oil spills from
reaching the water during transfers by:
(1) Pre-closing the scuppers/freeing
ports, if the towing vessel is so
equipped;
(2) Using fixed or portable containment of sufficient capacity to contain
the most likely spill, if 33 CFR 155.320
does not apply; or
(3) Pre-deploying sorbent material on
the deck around vents and fills.
(c) No person may intentionally
drain oil or hazardous material into

be greater than 24 hours; and
(5) Be marked so that an individual
not familiar with the operation of the
specific survival craft has sufficient
guidance to utilize the craft for its intended use.
(c) Compliance options. A towing vessel must meet the applicable functional requirements. Compliance with
the functional requirements of paragraph (b) of this section may be met by
one of these two options:
(1) A towing vessel that meets the
prescriptive requirements of paragraph
(d) of this section will have complied
with the functional requirements; or
(2) If an owner or managing operator
chooses to meet the functional require-
ment through means other than as
specified in paragraph (c)(1) of this section, the means must be accepted by
the cognizant OCMI or, if the vessel
has a TSMS, then by a TPO and, in the
latter case, documented in the TSMS
applicable to the vessel. The design,
testing, and examination scheme for
meeting these functional requirements
must be included as part of the TSMS
applicable to the vessel.
(d) Prescriptive requirements. (1) Except as provided in paragraphs (d)(2)
through (4) of this section, each towing
vessel must carry the survival craft
specified in Table 141.305 of this section, as appropriate for the towing vessel, in an aggregate capacity to accommodate the total number of individuals
onboard.

forktrucks, etc., where the machinery
location can change) unless adequately
protected.
(4) Connections and terminations
must be suitable for the installed conductors, and must retain the original
electrical, mechanical, flame-retarding, and where necessary, fire-resisting
properties of the conductor. If twist-on
types of connectors are used, the connections must be made within an enclosure and the insulated cap of the
connector must be secured to prevent
loosening due to vibration. Twist-on
type of connectors may not be used for
making joints in cables, facilitating a
conductor splice, or extending the
length of a circuit.
(5) Each cable and wire must be installed so as to avoid or reduce interference with radio reception and compass indication.
(6) Each cable and wire must be protected from the weather.
