Hazard
Non-combustible materials. If involved in a fire, will greatly intensify the
burning of combustible materials. Although non-combustible, mixtures with combustible
material are easily ignited and may burn fiercely.
This cargo is hygroscopic and will cake if wet.
This cargo is harmful if swallowed.
Stowage and segregation
"Separated from" foodstuffs.
Hold cleanliness
Clean and dry as relevant to the hazards of the cargo.
Weather precautions
This cargo shall be kept as dry as practicable. This cargo shall not be
handled during precipitation. During handling of this cargo, all non-working hatches of
the cargo spaces into which this cargo is loaded, or to be loaded, shall be closed.
Loading
Appropriate measures shall be taken to prevent the cargo from contact with
combustible materials.
Trim in accordance with the relevant provisions required under sections 4
and 5 of this Code.
Precautions
Bilge wells shall be clean, dry and covered as appropriate, to prevent
ingress of the cargo. The master and officers are to note that the ship's fixed gas
fire-fighting installation will be ineffective on fires involving this cargo and that
applying copious amounts of water may be necessary.
Ventilation
The cargo spaces carrying this cargo shall not be ventilated during
voyage.
Carriage
No special requirements.
Discharge
Calcium nitrate is hygroscopic and may cake in overhangs, impairing safety
during discharge. If this cargo has hardened, it shall be trimmed to avoid the formation
of overhangs, as necessary.
Clean-up
No special requirements.
Emergency procedures
| Special emergency equipment to
be carried
|
| Protective clothing (gloves,
boots, coveralls and headgear). Self-contained breathing apparatus. Spray
nozzles.
|
| Emergency
procedures
|
| Wear protective clothing and
self-contained breathing apparatus.
|
| Emergency action in the event
of fire
|
| Use copious quantities of water,
which is best applied in the form of a spray to avoid disturbing the surface
of the material. The material may fuse or melt, in which condition
application of water may result in extensive scattering of the molten
materials. Exclusion of air or the use of CO2 will not control
the fire. Due consideration should be given to the stability of the ship due
to the effect of accumulated water.
