- Separated from...
- Separated by a complete compartment
or hold from...
- Separated longitudinally by an intervening
compartment or hold from...

25. Solid Bulk Materials : Hazards
Hazards associated with the shipment of
solid bulk material come under the following
main categories :
1- Structural damage due to improper
distribution of the cargo.
2- Loss or reduction of stability due to
a shift of cargo or cargo liquefying.
3- Chemical reaction.
Ships in Service Training Material
A-M CHAUVEL

26. Solid Bulk Materials : Hazards
The Solid Bulk Carrier Code makes the
following distinctions :
- Appendix A
Bulk materials which may liquefy.
- Appendix B
Bulk materials possessing chemical hazards.
- Appendix C
Bulk materials which are neither liable to
liquefy nor to possess chemical hazards.
Carriage of grain is regulated under the International Code for the Safe Carriage of Grain.

27. Solid Bulk Materials : Hazards
High Density Cargoes
Require careful distribution within prescribed
limits to prevent over-stressing.
Danger of over-stressing is particularly
relevant when the ship is moving at sea.
In port, careful consideration must be given
to the sequence of loading and the quantity
of materials loaded at each port as well for
the technique used for unloading.
Structure damage, unless discover in time,
may result in the loss of the ship.

28. Solid Bulk Materials : Hazards
Cargoes Liable to Liquefy
Increase of moisture content above the transportable
moisture limit may result of liquefaction.
Liquefaction of cargoes results in loss of the
ship stability and possible loss of the ship.
Cargoes which may liquefy must be kept
in a dry or nearly dry state.
The shipper should provide the information.
Sampling procedures are specified in the BC Code.

29. Solid Bulk Materials : Hazards
Cargoes Liable to Shift
BC Code makes a distinction between cohesive
and non-cohesive cargoes.
The measure of the danger of shifting to which
a non-cohesive cargo is subject is given in
its angle of response.
Trimming instructions are specified for cargoes
with an angle of response:
- Less than or equal to 30°.
- 30° to 35°.
- Greater than 35° = Greater care.

Are classified in the similar way to packaged
dangerous goods:
Class Flammable solids.
Class Substances liable to spontaneous
combustion.
Class Substances in contact with water
emit flammable gases.
Class Oxidizing substances.

33. Dust should be reduced to the minimum.
Solid Bulk Materials : Hazards
Solid Bulk Materials posing Dust Hazards
Dust is inherent to cargo operations with many
bulk materials.
Dust should be reduced to the minimum.
Precautions are necessary to minimize the risks
due to exposure to the residual dust of certain
materials carrier in bulk.
High standard of personal is required with use
of protective clothing and barrier creams
particularly in case of toxic materials.

34. Sampling and laboratory test procedures are specified in the BC Code.
Solid Bulk Materials : Hazards
Solid Bulk Materials posing Dust Hazards
Dust created by certain cargoes may constitute
an explosion hazard especially during :
- Cargo operations.
- Cleaning holds.
The risk can be minimized by :
- Ventilating spaces with dust-laden atmospheres.
- Hosing down rather than seeping.
Sampling and laboratory test procedures are specified in the BC Code.

35. Solid Bulk Materials : Hazards
Information for Ships
To assess the dangers for those on board,
a shipmaster must be provide with the
information essential to load and unload
the ship safely.
The shipper should provide the shipmaster with
appropriate certificates of test with details as :
- chemical hazards.
- flow moisture point.
- stowage factor.
- moisture content.
- angle of response, etc…

These team mates are helping a colleague get into a safety harness. Any worker performing tasks more than two meters above ground must wear a safety harness that is tied off to a solid object to catch the worker and protect against injury in case of a fall. SFV-10 - This version of the WV-10 work vest, using Ensolite® flotation foam
, has a slot in the back to facilitate wearing a fall restraint harness.
