Hazard
No special hazards.
This cargo is non-combustible or has a low fire risk except when cargo
contains swarf (fine metal turnings liable to spontaneous combustion) refer to the entry
for FERROUS METAL BORINGS, SHAVINGS, TURNINGS or CUTTINGS UN 2793 in this Code.
Stowage and segregation
No special requirements.
Hold cleanliness
No special requirements.
Weather precautions
This cargo shall be kept as dry as practicable before loading, during
loading and during voyage. This cargo shall not be loaded during precipitation. During
loading of this cargo, all non-working hatches of the cargo spaces to which this cargo
is loaded, or to be loaded, shall be closed.
Loading
Refer to the appendix to this schedule.
Precautions
Refer to the appendix to this schedule.
Ventilation
Surface ventilation only, either natural or mechanical, shall be conducted,
as necessary, during the voyage for this cargo.
Carriage
Bilges in the cargo spaces carrying this cargo shall not be pumped unless
absolutely necessary. Bilgewater of this cargo may contain a certain amount of dirt and
oil from old machinery. Refer to the appendix to this individual schedule.
Discharge
When this cargo is discharged by magnet or spider grab:
- .1 the deck and deck machineries shall be protected from falling cargo; and
- .2 damages to the ship shall be checked, after the completion of discharge.
Clean-up
Prior to cleaning up the cargo spaces for this cargo, the crew shall be
informed of danger due to broken glass and sharp edges. Prior to washing out the
residues of this cargo, any oil spillages shall be cleaned from the tank tops and the
bilge wells of the cargo spaces for this cargo.
APPENDIX - SCRAP METAL
Handling of this cargo varies from magnets to spider grabs, depending usually on the
size of material. This cargo may include articles from the size of car bodies to fine
metal turnings (swarf). The weight of individual pieces will also vary greatly, ranging
from heavy machinery to tin cans.
Loading
Before loading, the cargo spaces shall be prepared as per general loading practice and
any areas liable to be damaged by falling cargo shall be protected with dunnage. This
includes decks and coamings in way of the material's path to the cargo spaces. Removing
the ship's side rails may be advisable.
A layer of this cargo shall be carefully placed over the tank top in the square to
cushion any fall out. Magnet and grab drivers shall be instructed not to release their
loads too high above the pile.
The usual method of loading is to form a pile along the ship's centre line and use the
slope to roll material into the ends and sides. Every effort must be made to work the
wings and ends to evenly distribute the weight. If this is not done, the light
high-volume pieces will roll to the wings and the small heavy pieces will concentrate in
the square.
When pumping the bilge wells, the master shall be aware that a certain amount of dirt
and oil can be expected from old machinery. Broken glass and sharp jagged edges may be
present and care shall be taken by personnel working near scrap.
Before hatches are closed, the cargo spaces shall be checked that no sharp projections
could pierce the ship's side.
