Paragraphs (f)(2), (g), and (h) of this section apply only to folding, sliding, or hinged metal hatch covers or to those hatch covers
handled by cranes.
When hatch covers or pontoons are stowed on the weather deck abreast of hatches, they shall be
arranged in stable piles not closer to the hatch coaming than three feet (.91 cm). Exception: On the
working side of the hatch, hatch covers or pontoons may be spread one
high between the coaming and bulwark with no space between them,
provided the height of the hatch coaming is no less than 24 inches (.61
m). Under no circumstances shall hatch covers or pontoons be stacked
higher than the hatch coaming or bulwark on the working side of the
On seagoing vessels, hatch boards or similar covers removed
from the hatch beams in a section of partially opened hatch during
cargo handling, cleaning or other operations shall not be stowed on the
boards or covers left in place within that section.
Hatch beams shall be laid on their sides, or stood on edge close together and lashed. Exception: This paragraph (b) shall not
apply in cases where hatch beams are of such design that:
The width of the flange is 50 percent or more of the height of
the web; and
The flange rests flat on the deck when the hatch beam is stood
Strongbacks, hatch covers, and pontoons removed from hatch
openings and placed on the weather deck shall not obstruct clear fore-
and-aft or coaming-to-bulwark passageways and shall be lashed or
otherwise secured to prevent accidental dislodgement. Dunnage or other
suitable material shall be used under and between tiers of strongbacks
and pontoons to prevent them from sliding when stowed on steel decks.
Hatch covers unshipped in an intermediate deck shall be placed
at least three feet (.91 m) from the coaming or they shall be removed
to another deck. Strongbacks unshipped in an intermediate deck shall
not be placed closer than six inches (15.24 cm) from the coaming and,
if placed closer than three feet (.91 m), shall be secured so that they
cannot be tipped or dragged into a lower compartment. If such placement
or securement is not possible, strongbacks shall be removed to another
Any hatch beam or pontoon left in place next to an open hatch
section being worked shall be locked or otherwise secured, so that it
cannot be accidentally displaced. All portable, manually handled hatch
covers, including those bound together to make a larger cover, shall be
removed from any working section, and adjacent sections, unless
The roller hatch beam at the edge of the open section of the hatch shall be lashed or pinned back so
that it cannot be moved toward the open section.
Rolling, sectional or telescopic hatch covers of barges which open in a fore and aft direction shall
be secured against unintentional movement while in the open position.
Hinged or folding hatch covers normally stowed in an
approximately vertical position shall be positively secured when in the
upright position, unless the design of the system otherwise prevents
Hatches shall not be opened or closed while employees are in
the square of the hatch below.
All materials such as dunnage, lashings, twist locks, or
stacking cones shall be removed from the hatch cover or be secured to
prevent them from falling off the cover before the hatch cover is
When a hatch is to be covered, hatch covers or night tents
shall be used. Any covering that only partially covers the hatch, such
as alternate hatch covers or strips of dunnage, shall not be covered by
a tarpaulin. Exception: A tarpaulin may be used to cover an open or
partially open hatch to reduce dust emissions during bulk cargo loading
operations, if positive means are taken to prevent employees from
walking on the tarpaulin.
